Yema Watch: Superman Skin Diver Cmm.20 Black

A contemporary evolution of an iconic 60s model, the Skin Diver CMM.20 marks a turning point in YEMA's history. With its brand-new French-made micro-rotor caliber, water resistance increased to 300 meters, and an innovative sapphire bezel, this diver does more than just pay homage to the past: it establishes itself as a modern benchmark in the watchmaking landscape.

Masterful vintage design

316L stainless steel case, vertically brushed with polished bevels, a contained diameter of 39.5 mm, and 11.5 mm thickness: the proportions are perfect. The subtly brushed black dial, applied indices, and luminescent hands offer optimal readability, day or night. The 2.20 mm double-domed sapphire crystal, with anti-reflective treatment, accentuates the vintage effect without sacrificing robustness.

Technical & secure bezel

This Skin Diver innovates with a bidirectional bezel featuring a sapphire insert and a unique locking system: "Push-to-unlock". It offers a 0 to 60-minute graduation and a luminescent marker at 12 o'clock treated with Grade A Super-LumiNova for effective reading in all conditions.

An exceptional watchmaking heart: the CMM.20

Under the hood, YEMA deploys its Calibre Manufacture Morteau 20:

• Automatic winding via tungsten micro-rotor

• 70-hour power reserve

• Chronometric precision: -3 / +7 seconds per day
  This movement, designed and assembled in Morteau, illustrates the brand's technical and artisanal move upmarket.

Bracelet & premium comfort

The integrated steel bracelet adopts the brushed finish of the case and includes a sliding micro-adjustment system, offering a precise and comfortable fit in any circumstance.
