Ride & Drive TIME CONTROL

The ARPIEM RD is equipped with a DOUBLE CASE in 316L stainless steel, featuring a glass case back that reveals the movement and the personalized rotor. The characteristics of this steel include a near-total absence of magnetism, ensuring it does not interfere with the movement's operation, and a very low carbon content (less than 0.35%), which makes it particularly resistant to corrosion and wear. A water resistance of 5 ATM is offered.

THE ROTATING DIAL: The RD offers a rare complication: a rotating dial that allows you to shift the dial by 60°, maintaining an intuitive reading of the time while at the wheel—or handlebars—of your car or motorcycle. The complication featured on the RD allows the dial to be locked in the traditional "12 o'clock" position (REST position), or shifted (DRIVE position) by 60° to the "2 o'clock" position. This is a unique feature developed by Arpiem.

THE MOVEMENT: MIYOTA 90S5 automatic. This movement belongs to the "9000 series," which makes up the brand's premium movements: mounted on 24 jewels, frequency = 28,800 vibrations per hour, 42-hour power reserve. It features an "open heart," highlighting the movement on the watch dial.

SAPPHIRE CRYSTAL: This is the highest quality crystal available on the market. It is actually an aluminum oxide crystal, not glass. Although 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 to evaluate mineral hardness, it is rated at 9; only diamond is harder, rated at 10. Most minerals found in our everyday objects are between 4 and 7 on this scale.

ANTI-REFLECTIVE TREATMENT: The crystal is treated with 6 layers of anti-reflective coating designed to limit light refraction on the sapphire crystal for perfect perception of colors and textures (the higher the number of layers applied, the lower the light refraction).
