A0000005183

We are pleased to present at auction one of the most technical, dazzling, and purist pieces of contemporary French watchmaking: the luxury professional diving watch Yema Superman Slim CMM.20 Micro-Rotor. This model is a true engineering milestone for the brand, as it accommodates extreme diving specifications in an ultra-sleek and exquisitely elegant case profile. The piece is presented in impeccable condition, preserving its aesthetic and mechanical integrity.

The Heart of the Piece: Manufacture Caliber CMM.20

Through its sapphire crystal-decked exhibition back, the soul of this watch can be contemplated in all its splendor: the legendary Caliber CMM.20 (Caliber Manufacture Morteau 20). conceived, developed, and assembled entirely in Yema’s historic workshops in France, this movement stands out for its purist Micro-Rotor configuration. By using a high-density off-center oscillating weight instead of a conventional central rotor, Yema dramatically reduces the thickness of the mechanism without compromising automatic winding efficiency. Visually it is a work of art, showcasing a black-satinfinish plate and bridges, mirror-polished screws, and highly contrasted exposed rubies.

Detailed Design and Conservation Report:

Case and Safety Elements: The structure is made of high-strength surgical-grade stainless steel (Tout Acier). The unidirectional rotating bezel features a 60-minute scale in glossy black and is guarded by Yema’s iconic patented bezel-lock (Bezel-lock): a mechanical clamp linked to the screw-down crown that fixes its position to prevent accidental turns. The sapphire crystal is convex Double Dome hardened to the maximum. The case bears its official serial number 100 225 and guarantees professional water resistance of 300 meters (30 BAR).

Dial and Readability: The dial sports a deep glossy black finish (Glossy Black) of impeccable quality. It houses applied high-luminance indices and the classic hands from the Superman family, with the oversized arrow-shaped minute hand for perfect underwater legibility.

Bracelet of Scales and Size Specifications: The watch wears its original steel bracelet from the brand, characterized by its iconic interlinked scale-pattern design, internationally acclaimed for its flexibility and perfect ergonomics. The bracelet features a perfectly symmetrical and balanced distribution of 7 cm in length on each side (measured from the dial exit to the clasp anchor). In addition, the fold-over safety clasp (engraved with the official Yema logo) includes a generous hidden 4 cm dive extension, offering tremendous versatility to fit over a thick wetsuit or to provide an ideal adjustment margin for larger wrists.

An extraordinary opportunity for collectors and investors to acquire a French manufacture watch of the highest level, combining the historical robustness of the Superman line with the mechanical sophistication of a micro-rotor.

Care Recommendations

For the maintenance of this manufacture piece, it is advised to clean the case and scale bracelet with a soft dry microfiber cloth to remove fingerprints and natural oils after use. If used in saltwater, it is essential to rinse the watch under a gentle stream of warm water, ensuring beforehand that the crown is fully screwed down to maintain the 30 BAR sealing. Avoid subjecting the movement to dry impacts or extreme vibrations, and keep it away from strong magnetic fields (speakers, wireless charging bases) to preserve the official chronometry of caliber CMM.20.

It will be properly protected for flawless delivery.

Happy bidding for this magnificent Yema manufacture piece!
