Yema Skin Diver CMM.20

Supercharged with a micro-rotor Manufacture caliber, the Skin Diver CMM.20 is the modern interpretation of the iconic skin divers released by YEMA in the 1960’s. Rugged, yet stylish.

The Skin Diver collection is declined in 3 variants and available as from April 15, 2025 on pre-orders with delivery planned end of April 2025.

39.5 mm Skin Diver steel case

Conceived as a professional dive watch, the 39.5mm 316L stainless steel case (47mm lug-to-lug) stands out with its 20mm curved lugs and brushed finishes in contrast with the polished bevels.

Instantly recognizable by its unguarded crown, the steel case houses our CMM.20 micro-rotor caliber, while preserving a 30 BAR water resistance thanks to the sapphire exhibition case-back and the screw-down crown.

Ultra-legible Skin Diver dial

The complex dial layout provides a distinctive design element and excellent legibility by showcasing triangular-shaped hour markers complete with Arabic numerals.

All the elements are generously filled with vintage-inspired, lime-coloured Super-LumiNova and outlined in polished steel. Simply balanced, bold lumed markers and broad hands complement each other entirely.

The dial base has a slight brushed surface, reinforcing the old-school look, and contributing to accentuate the play of light of the polished steel raised markers and hands against the dial.

Sapphire bezel and "push-to-unlock" bezel-lock mechanism

The sapphire bezel is tinted to precisely match the dial, creating a unified and elegant appearance. The updated bezel-lock mechanism marks a notable evolution in both engineering design and user experience, while preserving the iconic identity of the Superman line.

In contrast to the original system, where a clamp was positioned above the bezel and secured via the crown, the new bezel-lock mechanism is fully integrated beneath the bezel, offering a cleaner aesthetic and a more seamless tactile experience. This results in a sleeker profile and a more modern, minimalist design, staying true to the Superman’s toolwatch heritage while enhancing its elegance.

Double dome sapphire crystal

The Skin Diver features a 2.2 mm thick double-dome sapphire crystal, offering better readability, increased resistance and a resolutely vintage look and feel.

Sapphire exhibition case back

The sunbeam Côtes de Genève finish of the caliber’s bridges stands out, the fan-like pattern radiating from the center, capturing light beautifully and highlighting the craftsmanship behind the movement.

Grade A Super-LumiNova

The hour markers, hands and bezel pipe are coated with Grade A Super-LumiNova for perfect readability even in the dark.

New scales slim bracelet with micro-adjustment

This new Scales Slim bracelet gradually tapers from 4mm at the buckle and naturally adapts to each wrist’s shape. It features a fully brushed finish, providing an elegant visual continuity with the brushed steel case.

The new clasp features an on-thefly adjustment mechanism, perfect for adapting to wrist swelling due to heat, activity, or time of day. The bracelet fit can now be adjusted instantly, without removing the watch or using any tools.
