Racematic TSR 2 "Bob WOLLEK"
Designed and assembled in France
THE CASE of the ARPIEM RACEMATIC is made of 316L stainless steel. Its features include a near-total absence of magnetism, which does not disrupt the movement's operation, and a very low carbon content (less than 0.35%), making it particularly resistant to corrosion and wear. It offers water resistance of 10 ATM. The watch's adjustment button is screw-down.
THE WATCH is assembled in France in Bordeaux
DLC CRYSTAL COATING: The DLC coating, Diamond Like Carbon, is a material combining the structure of graphite carbon with that of diamond and a variable amount of hydrogen deposited in thin layers under vacuum. Its name refers to the qualities of diamond found in DLC: resistance to wear, durability, and a low coefficient of friction. Thanks to these qualities, it is used in the design of drilling tools, engines, the optical industry, and, of course, watchmaking. The DLC treatment of the TSR 2 crystal gives it resistance to shocks and wear far superior to what would have been achieved with a standard PVD coating.
THE DIAL: the shape of the sub-dials (the "pandas") is inspired by the gauges of 1960s cars. The markers on the main dial represent the graduations of the tachymeter.
THE TRIPLE-LAYER DIAL DESIGN gives the ARPIEM an elegant volume, which also recalls the "sandwich" alloy construction of race car chassis before the advent of carbon fiber.
THE MOVEMENT: automatic MIYOTA caliber 9132 with power reserve. Set with 26 jewels. Frequency = 28,800 Hz.
THE DOMED SAPPHIRE CRYSTAL: it is the best quality crystal available on the market. It is actually an aluminum oxide crystal and not glass. Even though it is produced synthetically on an industrial scale, it has the same chemical composition and physical properties as natural sapphire. Its main virtue is its scratch resistance. On the MOHS scale graded from 1 to 10, which evaluates the hardness of minerals, it is ranked at 9; only diamond is harder and ranked at 10. Most of the minerals making up our everyday objects are between 4 and 7 on this scale. Its domed finish gives the watch its "vintage" look.
ANTI-REFLECTIVE TREATMENT: The crystal is treated with 6 layers of anti-reflective coating designed to limit the refraction of light on the sapphire crystal for a perfect perception of colors and materials (the greater the number of layers applied, the lower the light refraction).
THE TACHYMETER: this one has been redesigned. The markers are usually arranged irregularly around the dial. On the ARPIEM, they are placed like those on diving watches, with the speed given for every 5 seconds on the dial.
CASE BACK: it is equipped with a sapphire crystal revealing the engraved rotor of the automatic movement
