THE CONSTANT ESCAPEMENT AT A GLANCE

A true technical revolution that stunned connoisseurs when some prototypes of the innovative mechanism were first presented, the Constant Escapement is now integrated into the movements driving the new models of Girard-Perregaux’s Haute Horlogerie collection. It has taken five years of research and development in virtually unexplored territory to consolidate and ensure the reliability of this significant step in watchmaking history.

The name, in addition to being a nod to one of the Maison's historical figures, Constant Girard-Perregaux, also refers to a holy grail in mechanical watchmaking that has perplexed watchmakers since the dawn of time: the constant force. Keeping true to its innovative vision, the brand decided to try using a quite novel approach to achieve it.

The concept presented on that occasion in the form of a functional mechanism was breathtaking, promising and poetic: the design was lightweight and graceful. However, the goal was far from being the result of art for art's sake, this was a new and convincing answer to the age-old preoccupation in watchmaking: the precision and regularity of a mechanical watch. 
 
To get an idea of what is at stake and truly understand the importance of this innovation, it is worth recalling a few basic notions. The heart of a mechanical watch is ruled by the regulating organ, which manages the flow rate of the energy received from the barrel to drive the gear train and the rotation speed of the hands. The classic image is that of a faucet managing the flow of water.

The main factor is not so much the speed of the beats of this heart, the chosen frequency, but their regularity. The dance can be three in a bar or four in a bar, or even a thousand; but the essential thing is that it keeps the beat over time.

All sorts of systems had been dreamed up before the famous Swiss lever escapement was presented in wristwatches, and became more or less standard. Yet it suffers from one drawback: it can only give back the energy it receives from the barrel, which diminishes with time. This energy, which defines its timekeeping accuracy, is too fast to start with, and finishes like a machine running out of steam. A curve, the curse and the bane of watchmakers, illustrates the phenomenon: the curve of the amplitude, or angular displacement of a sprung balance wheel or a pendulum, which lessens towards the end of the run.

The principle of a constant force escapement is that whatever the energy supplied by the barrel, the escapement returns a constant energy to the regulator (balance wheel). To achieve this, they had the brilliant idea of integrating an intermediate device into the escapement, consisting of an extremely thin blade that stores the energy up to an invariable threshold bordering on instability, and then transmits it all instantaneously, before recommencing the cycle.

The inspiration came from an experiment, which anyone can repeat by holding a train ticket vertically between thumb and forefinger, bending it to form a C or an open round bracket. If you then apply pressure from the side you will feel resistance until the moment when the card snaps to the other side to mirror its former shape, and close the round bracket. Try it with a business card, it works every time.

The phenomenon of instability is known as buckling, which is the passage from a state of compression to one of bending. Spring specialists thus speak of buckled blades. Here, the silicon blade measures a quarter of a hair's thickness and plays the role of a microaccumulator of energy. This blade is flexed to a point as close as possible to its unstable state, and only needs an infinitesimal quantity of energy a micro-impulse given by the balance wheel (less perturbing than in a lever escapement) for it to snap from one state to the other, and in the process, to push the balance wheel forward, compensating for the variable energy of the barrel and liberating the same quantity of energy every time. 

Unlike other systems that propose a constant force averaged over time, this is an authentic constant force escapement, as the force is instantaneous and continuous. And indeed, it is quite measurable using laboratory testing methods. Drawback: it can only give back the energy it receives from the barrel, which diminishes with time. This energy, which defines its timekeeping accuracy, is too fast to start with, and finishes like a machine running out of steam. A curve, the curse and the bane of watchmakers, illustrates the phenomenon: the curve of the amplitude, or angular displacement of a sprung balance wheel or a pendulum, which lessens towards the end of the run.

The phenomenon of instability is known as buckling, which is the passage from a state of compression to one of bending. Spring specialists thus speak of buckled blades. Here, the silicon blade measures one sixth of a hair's thickness and plays the role of a micro-accumulator of energy. This blade is flexed to a point as close as possible to its unstable state, and only needs an infinitesimal quantity of energy a micro-impulse given by the balance wheel (less perturbing than in a lever escapement) for it to snap from one state to the other, and in the process, to push the balance wheel forward, compensating for the variable energy of the barrel and liberating the same quantity of energy every time.

Unlike other systems that propose a constant force averaged over time, this is an authentic constant force escapement, as the force is instantaneous and continuous. And indeed, it is quite measurable using laboratory testing methods.

The designers chose a symmetrical double construction. This was not for aesthetic reasons, but to balance the forces at the center of the balance wheel and avoid a concentration of constraints at that point in order to ensure totally unencumbered rotation.

The blade is formed in one piece with the frame which holds it by both ends and plays a decisive role in the very precise locking of the point of contact for the micro-impulse which will make it snap over. The relatively simple principle brings with it the need for absolute precision to put it into practice, which would have been impossible before the use of silicon and the arrival of new part manufacturing techniques, such as deep reactive ion etching (DRIE). The partnership with the CSEM (Swiss Electronics and Micro-engineering Centre) in Neuchâtel, Switzerland was decisive. Watchmaking experts and physicists carried out complex calculations to determine the characteristics of the blade, and the many factors governing the buckling point. In the end, the structure of the device incorporating the blade is monolithic. It is held in virtual levitation and undergoes no friction except at the moment of the impulse and the flexing of the blade. The energy of the blade is directly transmitted  back to the balance wheel.

Since the blade is the key element of the Constant Escapement, its natural vibration governed the choice of frequency: it will be 3 Hz (21,600 vibrations per hour) for the magic to work. But the future remains open, and tests have already been carried out at other frequencies. In any case, the challenge here is not about high frequencies.

The two escapement wheels look nothing like those found in a lever escapement. They have three teeth for a frequency of 3 Hz, and would need four for 4 Hz. The movement was designed to run for several days with a linear power reserve indicator on the dial, demonstrating the efficiency of this escapement in the long run. The energy is supplied by two barrels coupled in parallel (a new patented design): the cover and the ratchet are a single piece to maximize the thickness available and each drum contains two springs stacked in series. Two other patents have been filed: one for the blade naturally, filed back in 2008, the other for the incorporation of limit stops in a flexible system.

While silicon was the material of choice for its ideal properties in the design and manufacture of the blade, it may be replaced by other materials for escapement wheels, while the movement blanks are in brass coated in black PVD for a contemporary look. The movement's aesthetic is meant to be technical, three-dimensional, but also to give a nod to tradition, with references to the brand's icons such as its famous three Bridges, laid out in a fresh way on its dial side, while on the back there are two arrow bridges.

To cap it all, this revolutionary movement looks ahead to after sales servicing right from the drawing board stage: the whole of the escapement is a module and can be handled by a specialized watchmaker.

Meccaniche Veloci - Chrono Driver














Meccaniche Veloci - Chrono Driver NEW



                            BASELWORLD 2013: ALL SET FOR THE CHRONO DRIVER
                                  Meccaniche Veloci to present its new timepiece


Vicenza, March 2013 – Preparations for the forthcoming edition of Baselworld are underway at Meccaniche Veloci. The star of the show will be the new Chrono Driver, a modern take on the legendary “driver’s watch” worn by many of motorsport’s heroes.
The Chrono Driver, just like other timepieces in the “driver’s watch” category, is highly dynamic. Its case, which is supported by a titanium or carbon frame, is able to change angles so that the time can be read without losing grip on the wheel for even a moment.
As lovers of speed and motors shouldn’t need to sacrifice beauty, the latest “Motored by Italian Passion” creation is not just a performance timepiece but is also eye-catching. As with all Meccaniche Veloci watches, the Chrono Driver combines Italian design and Swiss-made precision movements ensuring a perfect unison of stunning aesthetics and exact time keeping.

Drivers Watch - background
Speeding around racetracks in the pursuit of time, there is no space for distractions. In the early 1900s, the leading racing drivers knew this and chose what was called a “driver’s watch”, a timepiece that could be worn on the side of the wrist. In 1937, the Gruen Watch Company launched the first Ristside driver’s watch as Bernd Rosemeyer at the wheel of a Union Type C set the new world land speed record over a mile at 406km/h and Tazio Nuvolari celebrated victory on the circuit of Milan in his Alfa Romeo 12 C-36.

BREVA - GENIE 01 Limited Edition








BREVA - Génie 01 Limited Edition NEW

Profile of Breva founder, Vincent Dupontreué

Breva founder Vincent Dupontreué was born just outside Paris in 1977. He had a precocious entrepreneurial spirit that had him making and selling bracelets on the beach in Corsica during holidays when just 11 years old and at 13 building and selling skateboard ramps with his brother. A job working in a bespoke men’s clothing store at 18 led, a few years later, to the position of sales manager at Ermenegildo Zegna. Vincent quickly decided he wanted to run his own boutique and when that wasn’t a possibility – he was still only 22 years old – he set up his own fashion brand, called ‘Vincent Dupontreué’..


After seven successful years Vincent sold his fashion brand, did an MBA in Lausanne, Switzerland, and ran an art gallery for a couple of years.

On his 33rd birthday in 2010, a desire for a nice watch ignited his entrepreneurial spirit once again and he decided to launch his own high-end Swiss brand. A beautiful weekend on Lake Como in Northern Italy provided both the inspiration for the name, Breva –  ‘La Breva’ is a warm southern wind contributing to the agreeably mild micro-climate around Lake Como – and the idea of creating a mechanical timepiece that forecast the weather.

In 2013, after three years of research and development, led by Jean-François Mojon/Chronode to his specifications, Vincent launched the Génie 01.

Génie 01 by Breva
It’s sunny on your wrist no matter the weather!

The Breva Génie 01 is the world’s first wristwatch with time, altimeter, barometer – for forecasting the weather – and power reserve indications provided by a fully mechanical movement, much of which is on display through the open dial and display back. The proprietary movement of the Génie 01 was developed exclusively for Breva by Jean-François Mojon/Chronode. 
A dial side tour reveals a plethora of easy-to-read indications to keep the wearer fully informed about current time, altitude, remaining power in the mainspring, and a weather forecasting barometer.

Click on the mouse wheel to see the large size BIG FOTO ....
 


















Hours and minutes are displayed on a semi-transparent smoky-sapphire sub dial at 8 o’clock, with small seconds below 12 o’clock. A scale displaying altitude arcs around the top perimeter of the ‘dial’. Barometric pressure is indicated on a second semi-transparent smoky-sapphire sub dial at 2 o’clock, with icons providing scientifically based forecasts of likely weather conditions to come.

Click on the mouse wheel to see the large size BIG FOTO ....





























A 65-hour power reserve indicator at 4 o’clock is instantly recognizable thanks to its engraved compass rose – an icon found throughout Génie 01. At 6 o’clock, an anaerobic capsule measuring air pressure dominates the lower section, with another identical anaerobic capsule underneath it to maximize sensitivity to the slightest change in air pressure.

Three dual-purpose crowns on the case band provide power to, and allow setting of, the proprietary Breva movement. On the left at 9 o’clock, a two-position crown is dedicated to winding the watch and setting the time. On the top right at 2 o’clock, a knurled exterior ring adjusts the barometric pressure scale, while an inner pusher adjusts the position of the altitude indication.

Click on the mouse wheel to see the large size BIG FOTO ....




























At 4 o’clock, a second crown on the right has a knurled locking ring that rotates 90° to lock/unlock an air valve. When unlocked, the valve opens and allows a small amount of air to equalize air pressure inside the case with the exterior air pressure. Longevity and reliability of the timepiece are maximized by means of an osmotic Teflon membrane that filters any moisture from any air before it enters the movement. Just above the crown, a red indicator on the dial marked ‘SEALED' warns when the valve is unlocked.

Click on the mouse wheel to see the large size BIG FOTO ....


















The technological and visual feast continues through to the back of Génie 01. A circular scale engraved around the perimeter of the caseback provides a scale providing correlations between altitude and air pressure, as the altitude affects air pressure as well as the weather.

Click on the mouse wheel to see the large size BIG FOTO ....















 


Through the sapphire crystal display back, it is the vibrantly oscillating balance wheel that first catches the eye; however a more carefully inspection unveils yet more of the beautifully finished movement. When winding the movement you can see compass roses rotating on the cap of the mainspring barrel.

The name ‘Breva’ is inspired by ‘La Breva’, a warm southern wind that contributes to the agreeably mild microclimate around Lake Como in northern Italy. Breva Watches breathes a refreshing breeze through the often-stuffy world of Swiss haute horlogerie.

Génie 01 is a limited edition of 55 pieces in white gold and 55 pieces in 4N pink gold.



The anaerobic barometer and altimeter in the Génie 01 

A barometer is an instrument for measuring air pressure, first invented by Evangelista Toricelli, a pupil of Galileo, in 1643. There are two main types of barometer: a mercury barometer, in which the pressure of the air forces a small column of mercury up a tube (similar to a mercury thermometer); and the anaerobic barometer, in which one or more aneroid capsules (aneroid means ‘without air’) expand/contract with changing air pressure.
The barometer and altimeter (air pressure changes with both altitude and weather conditions) measure air pressure with two small aneroid capsules stacked one above the other – the top one being clearly visible on the dial side at 5 o’clock.
Click on the mouse wheel to see the large size BIG FOTO ....



















The aneroid capsules in the Génie 01 were especially developed to Breva's specifications to optimise their precision and use in a wristwatch.  The capsules are made from a special non-magnetic memory-metal (Breva patented invention), which is lighter and stronger than aluminium and has twice the ductility of steel. The capsules are exposed for long durations to high temperature and pure oxygen to maximise thermal conductivity and oxidation resistance.
A clearly visible lever rests on top of the aneroid capsules and transmits the combined height of the capsules through a complex system of gears and racks to the altimeter indication and the barometer. The gearing for these two displays has been carefully calculated as the scale of changing air pressure due to altitude variations is quite different to weather variations.
The attitude display reads from -300 to +5,300 metres, while the barometric display ranges between 973 and 1053 hectopascals (hPa). In a nod to the original method of measuring air pressure in inches of Mercury, an inner scale of the barometer is marked mmHg: Hg being the atomic name for Mercury (Hg from the Greek hydrargyrum meaning ‘silver water’).

The Génie 01 barometer 
 Before using or adjusting the barometer, air pressure inside the movement should be equalised with the exterior air pressure using the valve at 4 o’clock.

Click on the mouse wheel to see the large size BIG FOTO ....




















What is important in using air pressure to forecast the weather is the recent change in pressure, rather than the pressure itself. Rising pressure indicates good weather coming, falling pressure is a sign of inclement weather ahead. The faster the pressure changes and/or the larger the change, the more extreme – good or bad – the coming weather is likely to be.

After equalising the interior air pressure, the barometer dial is rotated so that the hand points through the centre of ‘météo’ (French for weather forecast) to 1013 hPa, which is the standard (not necessarily actual) air pressure at sea level. Over the next hours – assuming no change in altitude – the hand might remain in place, indicating no change; move toward lower pressure, suggesting a possible deterioration in the weather; or move towards higher pressure, suggesting sunny weather coming on its way. Slow/small movement suggests minor changes, while fast and/or large movement forecasts more extreme weather ahead.

The Génie 01 altimeter
Before using or adjusting the 5,300m/17,000' altimeter, air pressure inside the movement should be equalised with the exterior air pressure valve at 4 o’clock.
Click on the mouse wheel to see the large size BIG FOTO ....



















Because air pressure can vary throughout the day (due to weather changes) the altimeter should be regularly set at a known altitude to ensure accurate results. As the hand is directly linked to the air pressure, the pusher at 2 o’clock moves the altitude dial (rather than the hand) left or right to synchronise the correct altitude with the indicator hand.

Air pressure and weather forecasting

Air pressure is caused by the gases in the atmosphere – mainly nitrogen (N2) and oxygen (O2) – pushing in all directions (think of gas in a balloon). These gases may be relatively light, but there are a lot of them in the atmosphere stretching approximately 24 kilometres (15 miles) above our heads. Air density/pressure varies due to: temperature – hotter air is less dense so floats above cool air; altitude: the closer air is to the planet’s surface – the more gravity packs its molecules together so increases its density; and humidity.
Why clouds float
Paradoxically water vapour molecules H2O – two hydrogen (lightest matter in the universe) plus one oxygen – are actually lighter than air molecules, which are approximately 80% N2 (two nitrogen atoms) and 20% O2 (two oxygen atoms). That’s one – though not the only one – of the reasons clouds float! Note that liquid water is much heavier than water vapour, which is why it rains.
Winds
Because of the earth’s rotation, angle, sun striking half the surface, oceans and ice caps, the air temperature – and air pressure – varies throughout the day, the seasons and the years. These variations cause colder and hotter regions in the atmosphere. Colder regions are denser than warmer regions so have higher pressure. High pressure moves towards low pressure (prick a balloon and the gas rushes out, not in) causing wind.
Wind moving from high pressure to low pressure are between a rock (earth’s surface) and a hard (high-pressure) place, so there is nowhere for all that incoming air to go. Nowhere to go… except UP! 
Extreme weather
When the air pressure drops very low, massive amounts of air are forced upwards so fast that they spin to form whirlwinds, tornadoes, cyclones and hurricanes. Note that cyclones and hurricanes are similar phenomenon but spin in different directions due to the Coriolis effect: cyclones rotate anti-clockwise in the southern hemisphere, hurricanes clockwise in the north.
Water spinning down the plug
However, while the Coriolis effect influences light air over thousands of kilometres, despite widespread belief it is far too weak to influence the direction small amounts of relatively heavy water spin down the plughole. That’s just an urban myth!
Come rain or hail
So in areas of relatively low pressure, air generally rises up. And as it rises, the air cools and the molecules of water it contains condense into water vapour that eventually forms white fluffy clouds. However, if the air pressure is low enough, the winds will be stronger so the incoming air will rise even higher where the lower temperature of the air can no longer support the ever denser water molecules, so they precipitate into rain, snow or even freeze as hail.
Changes
But predicting the weather isn’t quite that simple because it isn’t the actual air pressure that forecasts the weather – knowing the air pressure just tells you what you can learn by looking out the window, i.e. what the weather is now, not what’s coming. It is the change in air pressure that indicates what weather is coming, rather than the actual pressure itself.

Da Vindice - Vindex Tourbillon



















Da Vindice - Vindex Tourbillon NEW Basel 2013



HISTORY

It all began in Ancient Rome, where freedom fighter Giulio Vindice initiated the rebellion against the Emperor Nero, leading an extraordinary lineage of family history that will forever resonate. Freedom of expression, creativity, research and discovery; a family tradition that is clearly preserved centuries later through descendant Cosimo Vindice, founder of Haute Horlogerie brand Da Vindice Genève.
Born and raised in Switzerland, Cosimo Vindice grew up in the heart of the watch making world, which graciously formed his knowledge and helped him develop an expertise in this realm that he became so passionate about - and to him, passion is everything.

Tradition, heritage and respect will always play key roles in the development of future Da Vindice timepieces, alongside modernism.

A combination of creativity, technique, and spirit of innovation defines the essence of Da Vindice and its first Vindex Collection. The Vindex « Tourbillon-Barometer », a limited edition timepiece that was unveiled as a world premier "Grand Complication" in 2010 at the prestigious Grand-Prix d'Horlogerie in Geneva, is fitted with a unique complication: an aneroid barometer.

The Vindex Collection’s Tourbillon Barometer features a mechanical automatic-winding movement, endowed with a central tourbillon and an aneroid barometer. Despite its mechanical complexity, the Tourbillon Barometer ensures water resistance to 3 ATM.
While the barometer was first introduced around the year 1840 and contributed to the birth of meteorology, Da Vindice revisits this instrument bringing to bear its new position at the heart of a timekeeper. The type of barometer used in this watch is an aneroid barometer. The atmospheric pressure is managed in a capsule, known as a « Vidie Capsule », hermetically sealed with the air partially removed from it. The walls of the capsule are held apart by a spring. Small changes in atmospheric pressure cause the capsule to expand or contract, and a mechanical system can amplify the movements resulting from the changes in pressure to make them visible on the dial.
The empty zone influencing the aneroid capsule is placed at 10 o’clock, this way the watch is more reactive to ambient air than to body temperature.
