Yema Superman Slim CMM.20

Equipped with the Manufacture micro-rotor caliber CMM.20 and available in two colours, this sleeker version of the iconic Superman model features a completely redesigned and thinner 39mm case with elegant finishes. The new 20mm Scales Slim bracelet naturally integrates within the curved lugs of the case and gradually tapers towards the buckle.

This slim and versatile interpretation of the Superman fits all wrists and can make a sophisticated statement when worn with formal attire.

CMM.20 - Calibre Manufacture Morteau 20

After over 2 years of development and several thousand deliveries, the Manufacture micro-rotor caliber is now in continuous production within Yema's workshops in Morteau. The internalization of manufacturing and a sharp increase in production enable us to offer a highly performant and unique caliber at an extremely competitive price.

Caliber designed in Switzerland and developed in France. Bridges and mainplates manufactured in YEMA’s Morteau workshops. Due to its smart architecture resulting in a contained thickness of just 3.70 mm, this new caliber equips sleeker and refined cases. Optimised mechanical accuracy with near chronometer-certified performance. The power reserve has been enhanced to 70 hours thanks to innovating Tungsten micro-rotor and a large barrel.

This new 39mm 316L stainless steel case stands out with its 20mm curved lugs and brushed finishes in stark contrast with the polished bevels. Originally conceived as a professional dive watch, the steel case has been slimmed down by 1mm to accommodate the CMM.20 micro-rotor caliber, while preserving a 30 BAR water resistance thanks to the sapphire exhibition case-back and the screw-down crown.

New enamel lacquered dials "Manufacture Française"

The highly refined enamel lacquered dial proudly displays the mention "Manufacture Française" at 6 o’clock to reflect YEMA’s new positioning following the internalization of the manufacturing of components for the CMM calibers and the local production of casings.

The classic Superman hands in polished steel have been slightly refined while the iconic “shovel” sweep seconds has been replaced by the original seconds hand of the legendary Superman 53.00.16.

The new enamel lacquered dial offers a dazzling shine, and at some angles, it reflects a milky texture. The deep dial color accentuates the play of light and magnifies the reflections of the two convex sides of the double-domed sapphire crystal.

Sapphire bezel & Grade A Super-LumiNova

The rotating bezel stands out both for its complex design and its quality of finish. It is entirely made of sapphire and is in perfect harmony with the enamel lacquered dial and the brushed finish of the case. This redesigned bezel features a unidirectional rotation, a 0-60 simplified scale, and a luminescent marker at 12 o’clock treated in Grade A Super-LumiNova.

Bezel-lock mechanism since 1967

The Superman’s bezel-lock mechanism linked to the crown has proven to be highly useful for professional divers and has been a consistent inclusion in all Superman models since end 1960s. This mechanism was patented by YEMA in 1967 in France and in 1968 in the United States. The lock works by pulling out the screw-down crown, adjusting the bezel, and then resecuring the crown, thus pushing the lock against the bezel and securing it.

30-bar exhibition case back

Luxury watches can inspire for a variety of reasons. It’s not only the design and the style of the timepiece but also the technical aspects of a fine timepiece that can really blow watch enthusiasts away. The sapphire exhibition case-back is an elegant feature for those who enjoy taking a look at the inner workings of their mechanical timepieces, in this case it allows wearers to catch a glimpse into the inner intricacies of the Manufacture micro-rotor caliber CMM.20, a rare caliber worthy of showcasing. Each case-back is engraved with a unique serial number also displayed in the 5-year warranty card.

Double-domed sapphire crystal

The Superman Slim features a 2.00 mm shock-resistant and scratch-resistant double-domed sapphire crystal. Its curved shape gives it a very unique, resolutely vintage look, while offering better readability thanks to its two convex sides as well as increased water resistance up to 30 BAR.

New scale slim bracelet

The iconic 1960s YEMA Scales bracelet has been slimmed down by 0.40mm so as to harmoniously integrate with the Superman Slim thin case. 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.
