The SIO – Italian School of Watchmaking was founded by Locman in 2006 with the intention of establishing a research centre and constant monitoring the quality of their watches. Over the years, SIO has certified and also developed the mechanisms of its major collections, partnering with companies for special projects.

Marco Mantovani, LOCMANSpa chairman, says: “We were able to develop a completely reliable, sturdy self-winding module. Our engineers also focused on the rotor weights so as to optimise the bidirectional winding stored by the self-winding mechanism for an average of up to about 50 hours.”
The oscillating weight is enhanced with a bright yellow shade and personalised with the LOCMAN ITALY logo. The calibre reference – SIO/DPch 88 – is indicated on the movement mainplate.

After upgrading the Montecristo’s movement, the SIO engineers went one step further and also revisited the design, giving it some extra competitive edge. The dial features sunray-pattern enamelling, the minute counter is placed at 3 o’clock and the small seconds subdial at 9 o’clock, while the tachometric scale – absent in the quartz version – appears around the inner bezel ring of this model.

The AISI 316L steel and titanium case is made of exclusively non-allergenic materials usually found in surgical instruments, and is topped by a flat glass with a special sapphire treatment to give the material a hardness comparable to that of natural sapphire as well as an exponential increase in its transparency. Tested waterresistant to 10 atmospheres, the Montecristo Crono case is attached to the silicon or hi-tech Lorica strap by the distinctive triple-bar lugs.

------------------------------------------- History
LOCMANwas founded in 1986 by Marco Mantovani. In 1997, LOCMAN decided to
give up producing watches for other brands and to launch its first
own-name line of original models. LOCMAN aims to occupy a niche market with products featuring innovative
designs, but distinguished by high-quality craftsmanship and
refinement, in order to meet the demands of a category of consumers
looking for original, exclusive and trendy products.
Thanks to the Linea Sport in 1999 and to the DIAMOND-Alluminio models
in 2000, which featured a tonneau-shaped aluminium case with a
non-allergenic strap in Lorica, timepieces by Locman Italy have become
cult models featuring a striking blend of ambition and casual
confidence that have earned them favour among the greatest international
celebrities.
Today,
the LOCMAN group is one of the major players in the Italian watch
industry. The mother company is LOCMAN Spa, which has headquarters in
Tuscany, on the island of Elba, and a network of offices spread
between Florence, Milan and New York.
The heart of LOCMAN watches beats in Elba, where ideas are born and
technical and commercial strategies are developed. The other production
phases take place in Milan, within the Genesi industrial facility,
considered to be the most efficient and modern laboratory in the
Italian watch business. Meanwhile, the communication strategy and
relations with the mass media are handled by Marchio Giallo, the Locman
Group’s in-house advertising agency.
Arnold & Son Unveils the World’s First True Beat Seconds and Chronograph Wristwatch: the Instrument CTB
With rich British heritage and unparalleled style, Arnold & Son never ceases to amaze and delight watch lovers with its deft blend of respected watchmaking tradition, visionary ingenuity and untiring commitment to excellence. A grand example of the brand’s unflagging Haute Horlogerie prowess can be found in the all new CTB – a world premiere.
The CTB joins Arnold & Son’s Instrument Collection – and, like every other model from Arnold & Son, features an in-house mechanical movement. This line is inspired by the timepieces produced during the second part of John Arnold’s life when he and his son, John Roger, dedicated themselves to the quest for absolute precision (thereby establishing themselves as official suppliers to the Royal Navy).
Click on themouse wheelto seethe large size ... BIG FOTO
Underscoring its continued commitment to forward-thinking precision, Arnold & Son’s watchmaking experts masterfully rose to challenge of creating a World’s First in a wristwatch: a chronograph with a central true beat seconds hand. The magnificent CTB represents the brand’s second chronograph and blends the iconic Instrument Collection complication of a true beat seconds, while at the same time remaining true to the line’s optic code of superb legibility. This aesthetic direction has been achieved by incorporating a central true beat seconds hand and a central chronograph seconds hand – both on the same axis but with different jumping intervals. A huge technical challenge to have both functions operating from the centre, Arnold & Son’s unique invention is protected by two patents.
Click on themouse wheelto seethe large size ... BIG FOTO
Sometimes referred to as a dead beat seconds, the true beat seconds is a precision function wherein the seconds beat incrementally as opposed to sweeping along the dial – allowing for more accurate reading. To accomplish this function in and of itself is no easy feat. However, Arnold & Son has taken the idea to new heights by incorporating the true beat seconds on the same axis as the chronograph seconds hand. The result, when the continually running chronograph hand is started, is visually amazing. It gives the impression that it can catch up to the true beat seconds hand, but this never happens since the true beat seconds hand jumps away each second in a delightful and entrancing game of cat and mouse.
The A&S7103 calibre is a proprietary mechanical self-winding movement with column-wheel operated chronograph. The movement is configured to give optimum balance and beauty to the dial, with off-centered hour and minutes at 12 o’clock, big central true beat seconds and central chronographs seconds, and 60-minutes chronograph indicator at 6 o’clock. The 31-jewel movement beats at 28,800 vibrations per hour and offers more than 50 hours of power reserve. This world’s-first timepiece also offers the efficiency of bi-directional winding thanks to ceramic ball bearings.
Click on themouse wheelto seethe large size ... BIG FOTO
Each movement is NAC grey treated and meticulously completed in Haute Horlogerie finishing with hand-chamfered bridges with polished edges, fine circular graining and Côtes de Genève rayonnantes, brushed and skeletonised rotor, and screws with bevelled and mirror-polished heads. The 44 mm stainless steel timepiece is offered with a light-grey and silvery opaline dial. The dial has a complex multi-level structure with at least three different finishes that offer breathtaking depth and dimension.

The Breva Génie 02 Air combines the stunning sophistication of a beautifully crafted mechanical timepiece with the practicality of a fully functional, high-performance altimeter. Whether your passion is paragliding, flying, skydiving, hang gliding, mountain climbing, skiing, or simply enjoying the fresh air and stunning views that high altitudes offer, the Génie 02 Air is the perfect companion.
The black titanium case of the Génie 02 Air offers a subtle but stunning backdrop to the high-legibility hands and markers, ensuring that essential information, i.e. time and altitude, is easily visible at a glance.
The superbly finished proprietary movement, much of which can be fully appreciated through the open dial and display back, was developed exclusively for Breva by award-winning movement constructor Jean-François Mojon (Chronode). The Génie 02 Air is 100% Swiss-made, from inception to realization.
The dial side of the timepiece is dominated by a sub-dial at 8 o'clock displaying hours and minutes, and the precision altimeter sub-dial at 2 o'clock displaying meters (or feet). Arcing around the top of the dial is the large-scale altitude indicator, which displays up to 5,000 meters (or 16,400 feet), with small seconds below. At 4 o'clock, an indicator is revealed when the air valve is open or closed (it must be open to indicate the altitude). Below is the 65-hour power reserve indicator.
In pride of place at the bottom of the dial is one of two aneroid capsules measuring air pressure (from which the altitude is derived), with a high-precision arm multiplying by 200 the expansion and contraction of the capsules and relaying the air pressure to the two altitude indications.
Click on themouse wheelto seethe large size ... BIGFOTO
Three chevron-engraved crowns wind, set, adjust, and operate the functions of the Génie 02:
9 o'clock: a two-position crown both winds the movement and sets the time.
2 o'clock: a screw down crown rotates both the altitude's precision-scale and large-scale to adjust for variations in air pressure, which affects altitude readings.
4 o'clock: a screw down crown either seals air out of the movement or allows it in (for altitude function). Longevity and reliability of the timepiece are maximized by means of an osmotic Teflon membrane that filters any moisture and humidity from air before it enters the movement. Just above the crown, a red band on the dial marked “SEALED” warns when the valve is unlocked.
Click on themouse wheelto seethe large size ... BIGFOTO
Turning the Génie 02 Air over allows the complexity of beautifully finished 415-component movement to be more fully appreciated. The movement is framed by the code names of many of the world's airports, engraved around the perimeter of the caseback along with their altitudes above sea level: GVA430M, HND6M; SYD9M; JFK/LHR24M; SIN7M; DXB19M; HKG9M; LAX38M; GYD3M; CDG119M; BCT4M; CVF2008M; OLB37M; IBZ6M; MIA2M; KUL22M; LTT18M; CGK10M; BGI52M. How many of these airports do you recognize?
Winding the movement makes the rotation of the mainspring barrel cap visible.
The Génie 02 Air is a limited edition of 55 pieces in titanium G5 and is available with calibrations in either meters or feet.

Génie 02 Air Details
High performance mechanical altimeter: paradoxically, an altimeter doesn't really measure altitude at all: it measures air pressure. In 1928, German inventor Paul Kollsman revolutionized the aviation world when he invented the world's first accurate barometric altimeter.
An air pressure altimeter is in fact a barometer developed specifically to display altitude rather than barometric pressure. Pressure in the earth's atmosphere is a result of the weight of the air pulled down by gravity. The higher the altitude, the less atmosphere above, so less pressure is exerted.
Aneroid capsules: the aneroid capsules in the Génie 02 were especially developed to Breva's specifications to optimize their precision and use in a wristwatch. The capsules are made from a special non-magnetic memory metal (a Breva-patented invention), which is lighter and stronger than aluminum and has twice the ductility of steel. The capsules are exposed for long durations to high temperature and pure oxygen to maximize thermal conductivity and oxidation resistance.
The Génie 02’s aneroid capsules were developed specifically for registering air pressure for altitude readings rather than barometric pressure, and are different from those used on the Génie 01.
A lever, clearly visible on top of the aneroid capsules, transmits the combined height of the capsules through a complex system of gears and racks to the two precision, large-scale altimeter indications. The gearing for these two displays has been carefully calculated to optimize both precision and legibility.
Click on themouse wheelto seethe large size ... BIGFOTO
Adjusting for changes in air pressure: atmospheric pressure can change with weather, and this can affect altitude readings. When bad weather approaches, air pressure can fall, causing the altimeter in the timepiece to confuse this decrease in pressure with an increase in altitude.
In order to compensate for weather- or temperature-induced barometric pressure variations, the altimeter should be calibrated by using a known altitude or a known pressure value. A known altitude can typically be taken from a specific landmark on a topographic map. If a known altitude is not available, a known pressure value will suffice. Barometric pressure is measured several times per day and can usually be obtained from aviation weather reports.
Altitude has historically been measured using a calibrated barometer, which is essentially what a pressure altimeter is. A barometric altimeter measures air pressure, which decreases with increasing altitude due to less atmospheric pressure.
Flight Levels
A pilot must recalibrate the altimeter according to local air pressure at sea level, in order to take into account natural variations of pressure over time due to weather and temperature. If altimeters are not calibrated before flight, two aircraft could be flying at the same altitude even though their altimeters indicate that they are at different altitudes.
To ensure aeronautic safety, planes and air traffic controllers use flight levels, which is a nominal pressure altitude in feet divided by 100 and always divisible by 500 (so always ending in 0 or 5), rather than actual height above sea level. For example, 33,000 feet is referred to as "flight level 330”.
Actual altitudes above ground are not as important for flight safety as the difference in altitudes between planes. This difference can be determined from the air pressure at each craft, and does not require knowledge of the local air pressure on the ground.
Flight levels solve this problem by defining altitudes based on a standardized air pressure at sea level. All aircraft operating on flight levels calibrate to this setting regardless of the actual sea level pressure.
A second advantage of flying at a consistent flight level, rather than true altitude, is that an aircraft's aerodynamic and engine performance depend on air pressure rather than its true altitude above ground or sea level. It is much easier to trim a plane to operate efficiently at a specific air pressure rather than altitude.
------------------------------------------------------------------------------------------ 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 building and selling skateboard ramps with his brother at
13. 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 Dupontreuéquickly
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 Dupontreuésold 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, the 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, Vincent Dupontreuélaunched Breva with the Génie 01,
the world’s first mechanical wristwatch displaying time, altitude,
weather forecasting barometric pressure and power reserve. This was
followed in 2014 by the Génie 02, which features a fully functional precision mechanical altimeter, as well as time and power reserve indications.

Magister Tourbillon features a hand-finished 60-second tourbillon in a
white-lacquered dial. The platinum micro-rotor powering the
automatic-winding movement can be appreciated through the display back
of the grade 5 titanium case.
Magister Tourbillon brings together everything that is quintessentially Speak-Marin: an eye-catching tourbillon, sculpted heat-blued hands, iconic Piccadilly case, fluted crown and finely finished movement, here featuring a platinum micro-rotor. MagisterTourbillon radiates a sophisticated aura, exuding the class and refinement for which Speake-Marin has become a byword.

The beautiful hand-finished tourbillon rotating at 6 o’clock is framed superbly by its stainless steel guard. The eye-catching, highly polished tourbillon bridge is made from Durnico maraging steel, chosen for its superior strength.
The tourbillon has played an important role in the story of Speake-Marin. The first timepiece ever to bear the Speake-Marin name was the Foundation Watch, a hand-made pocket watch which Peter Speake-Marin equipped with a tourbillon escapement. The watchmaker’s topping tool wheel motif in the Speake-Marin logo, which first appeared in the tourbillon cage of the Foundation Watch, can also be seen in the tourbillon cage of the MagisterTourbillon.

PeterSpeake-Marin recognises the tourbillon’s capacity to improve timekeeping accuracy by averaging out positional errors due to gravity. However, it is the visual aspect of this mesmerising escapement that draws him to it. “The tourbillon is one of the things that I love most about watchmaking,” he says. “Not because of the precision it gives to the timekeeping, but because of the animation it gives to the dial. It shows time moving in a way that a minute-repeater or a grande sonnerie, for example, won’t offer. It’s something which, for me, is extremely profound.”
Click on themouse wheelto seethe large size .... BIG FOTO
Of the topping tool wheel design for the tourbillon cage, Peter adds: “I have always been attracted to the topping tool because of its form. You use a tool to make a component, you make a timepiece, and the timepiece is a dream turned into reality. The topping tool motif is very much at the root of everything I do: It is the tool which gives me the means to realise my dream.”

MagisterTourbillon’s visually-arresting blued steel hands are also designed in the same style as the hands of the Foundation Watch, the Rosetta Stone of Speake-Marin. The polished, sculpted hands – including a heart-shaped hour hand – are set off superbly by the elegant white lacquer, multi-level dial. The sides of the highly legible Roman numerals taper towards the centre and follow the line of the hands. This subtle but significant detail endows the dial with a dynamic, contemporary feel.

The tourbillon – its one-minute rotation providing an intuitive indication of the passing seconds – contrasts beautifully against the pristine white dial. The “3Hz” frequency of the SM3 movement and the “platinum mass” of the winding rotor are referenced in the centre of the dial.

The lower tourbillon cage is supported by a striking paddle-shaped bridge offering clear visual access to the surrounding gears below. The rhodium-finished German silver bridges and movement plates are circular-grained with polished screw heads and countersinks. Technical details are engraved and gilded on the bridges either side of the platinum rotor.

The Speake-MarinMagisterTourbillon is available with a polished Grade 5 titanium case.
The “J Class” collection MagisterTourbillon launches the Speake-Marin "J Class" collection. After the exhilaration of a white-knuckle ride on a finely-tuned racing yacht – heeling on a broad reach with its rail near the ocean and spray cutting the air – comes the yacht club, replete with rich wood-panelled walls and vintage navigation instruments. And it is in the rarefied ambience of the club that the high-class pedigree of the Speake-Marin “J Class” timepieces – including MagisterTourbillon – comes into its own.

ARNOLD & SON– Instrument DSTB(Dial Side True Beat)Limited EditionNEW
BASELWORLD Novelty 2014 Arnold & Son is pleased to invite you to view our 2014 novelties presented at our A&S booth located in the PALACE 4E, March 27th – April 3rd
Arnold & Son Celebrates 250 Years with the Heritage-Inspired, Cutting Edge Limited EditionDSTB
Demonstrating its rich British history and quality Swiss craftsmanship, Arnold & Son unveils the limited editionDSTB (Dial Side True Beat). A tribute to the brand’s 250th anniversary, the DSTB is a testament to its heritage, vision and Haute Horlogerie ingenuity.
Click on themouse wheelto seethe large size ... BIG FOTO
The DSTB is part of the Instrument Collection and, like every other model from Arnold & Son, features an in-house mechanical movement. The true beat seconds is a traditional complication of Arnold & Son, and this watch pays tribute to the watches produced by John Arnold during the second half of his career, when he and his son were the first to develop marine chronometers that could be produced in quantity at reasonable prices. Those technically superior, widely distributed chronometers reflected Arnold & Son’s commitment to exceptional precision and solved the problem of determining longitude at sea.
Click on themouse wheelto seethe large size ...
Upholding that legacy, Arnold & Son’s master watchmakers thrive on creating complicated movements for exquisite timepieces. Such is the case with the DSTB watch, a truly innovative technical and architectural achievement. The newly developed automatic movement showcases the true beat seconds' mechanism entirely on the dial side. Not just the hands, but also the lever, wheels and three rose-gold treated true beat seconds bridges are located in all their beauty on the dial side. Making the watch even more alluring is the fact that the true beat seconds lever is shaped like an anchor – paying homage to Arnold’s maritime achievements.
Click on themouse wheelto seethe large size ... BIG FOTO
The true beat seconds are superbly indicated via a large sapphire dial that occupies the top left portion of the dial at 11 o’clock. At the 4 o’clock position, a white lacquered domed subdial indicates the hours and the minutes via blued hands. These generously proportioned, overlapping indications translate into a stunning three-dimensional dial.
Click on themouse wheelto seethe large size ...
This restructuring of the intricate mechanism yields a concept not achieved in the watch industry heretofore. The self-winding calibre A&S6003 has 229 components. In true Arnold & Son style, the movement features Haute Horlogerie finishing with hand-chamfered and satin-finished lever and bridges, polished edges and fine circular graining and Côtes de Genève rayonnantes. The visible dial plate is NAC grey treated with large circular finishing, and blued screws with bevelled and mirror-polished heads.
The magnificent timepiece is housed inside a 43.5 mm 18-carat red gold case with anti-reflective sapphire crystal and caseback for viewing the superbly finished movement, complete with skeletonised oscillating weight. The 250th anniversary edition of the DSTB will be limited to just 50 timepieces – underscoring the brand’s commitment to exclusivity and excellence.
