TWO YEARS AFTER THE EXTRAORDINARY INTERNATIONAL RECOGNITION GIVEN TO ITS FIRST WATCH WITH A BRONZE CASE


Officine Panerai presents the Luminor Submersible 1950 3 Days Power Reserve Automatic Bronzo, a new Special Edition produced in this material with its decisively nautical character which owes its fascination to the aged appearance it acquires with the passage of time.

The new feature which distinguishes this model is in the dial: the display of the power reserve of three days on an arc-shaped indicator positioned at four o’clock. This very useful function joins the date display, the device for zeroing the seconds hand that is invaluable when synchronising the watch with a reference time signal, and the system for rapidly adjusting the time, the hand of which can be moved forward or backwards in jumps of one hour without affecting the running of the watch. The dark green dial, with applied hour markers, is surrounded by a studded bezel in bronze with the scale for measuring the length of the dive. The bezel is connected to the case by a special system designed and patented by Officine Panerai to ensure that the ratchet moves precisely from one click to the next.

The case is the classic size for Panerai watches, 47 mm in diameter, fitted with the equally classic bridge device with the locking lever ensuring the water-resistance of the winding crown.
The sapphire crystal back is fixed by a titanium ring through which can be seen the Panerai P.9002 calibre, developed and produced entirely in the Officine Panerai manufacture. The Luminor Submersible 1950 3 Days Power Reserve Automatic Bronzo is water-resistant to 30 atmospheres (300 metres) and is completed by a brown leather strap with stitching of a subtly nautical character and a titanium buckle.

BRONZE


Bronze has a long history, dating back as far as the second millennium BC. At that time, it was used to produce items such as tools, weapons, musical instruments and armour, being stronger and tougher than its predecessors copper and stone. Bronze consists of copper with a variable percentage of tin. It may also contain varying amounts of aluminium, lead, beryllium, manganese and tungsten, sometimes with silicon and phosphorus as well.

Bronze is very versatile and it is highly valued for its many different uses: in the arts, in sculptures (80% copper and 20% tin) and for making bells (21.5 to 24% tin), the creation of hydraulic systems where the bronze alloy contains 10% of tin and 3% of zinc, and the more recent use of this material for ship propellers, where its high resistance to corrosion by seawater is invaluable. And in the past, since its resistance to corrosive seawater is much greater than that of iron, this alloy was used for the equipment of many yachts of yesteryear: portholes, handrails, cleats, winches and compass binnacles were made of bronze, and it was also used for divers’ helmets.

Its ancient history and its close links with the world of the sea make bronze the material that embodies the core values of Officine Panerai, which uses an alloy of copper and tin in the pure state. In addition to its high structural strength, this material retains its original warm tones while with the passage of time it acquires an aged appearance through the patina that covers it.
This patina is the result of the reaction of the bronze with external agents such as air, moisture, heat and friction. It does not alter the properties of the material, but it is evidence of ageing, giving each piece its own unique personality. The patina of the bronze is its skin: it is a protective layer, and as the surface of the metal becomes covered, it slows down any further oxidation of the metal.

Richard Mille - RM 011 Brown Silicon Nitride Сhronograph NEW
















Richard Mille - RM 011 Brown Silicon Nitride Сhronograph NEW

Inspired by the cutting-edge technologies used in Formula 1 racing cars to ensure exceptional accuracy and rigidity, the RM 011’s automatic caliber RMAC1 is now equipped with a flyback chronograph function that allows a timing operation in progress to be restarted without stopping the mechanism. This watch also boasts a variable geometry rotor, exclusive to Richard Mille, which optimises the winding of the barrel by adapting it to the user’s activities.





 


In 2013, Richard Mille presents a masterful reinterpretation of the RM 011 featuring a new material with a unique colour that has never been used in watchmaking before: brown silicon nitride.

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

































Brown silicon nitride is an extremely hard material (1,500 Vickers) that displays high resistance not only to wear and corrosion, but also to severe temperature variations. Very lightweight, it is used in the automobile industry to make valves, turbocharger rotors and other parts.

Its manufacturing process minimises porosity within the raw material. The powder is formed in an isostatic press where a pressure of about 2,000 bars is applied. The blank obtained by pressing is then heated to 1,500°C. A deviation of 10°C in temperature can alter the physical characteristics of silicon nitride at any moment. After 12 hours at extreme temperatures, the volume of a part will have diminished by more than 20%.























Silicon nitride is used for the bezel and case back of the RM 011. These parts are machined with diamond tools that are capable of performing the complex operations required by the barrel shape whilst guaranteeing strict tolerances and an exceptional case finish (satin-brushing and microblasting).

The satin-brushed case-middle, crown and push-pieces are made of 18-carat red gold, and the push-piece guards from polished grade 5 titanium. The RM 011 Brown Silicon Nitride is available from Richard Mille boutiques and the brand’s retailers.
