MILLÉSIME 2025 LIMITED EDITION
The finest expression of YEMA’s savoir-faire
With the launch of the Superman Tourbillon CMM.31, YEMA inaugurates a new era of Millésime Editions— yearly releases that showcase the pinnacle of our watchmaking know-how and in-house capabilities.
“Millésime” stands for the very best YEMA can produce: a premium, handcrafted, and highly limited timepiece that embodies the legacy of French horology and our ongoing pursuit of excellence.
For 2025, we chose our most iconic model, the YEMA Superman, a professional dive watch introduced in 1963, now re-imagined with our Manufacture tourbillon caliber that combines technical innovation, haute horlogerie finishing, and robust tool-watch specifications.
Limited to 100 numbered timepieces.
-3/+7 SECONDS ACCURACY
Optimised mechanical accuracy with near chronometer-certified performance.
105 HOURS POWER RESERVE
Increased power reserve thanks to a large barrel allowing optimized winding.
HIGH SHOCK RESISTANCE
Caliber impervious to shocks, vibrations, and acceleration up to 5,000 Gs in all directions.
FRENCH MANUFACTURE CALIBER
Caliber designed and developed by Olivier Mory. Micro-components (bridges and mainplates) manufactured in our YEMA workshops in Morteau.
A TOURBILLON BUILT FOR THE DEPTHS
Traditionally, tourbillons are fragile complications destined for dress watches. The CMM.31 caliber, developed by Olivier Mory and manufactured by our team in Morteau, France, breaks this paradigm.
Based on the proven CMM.30 architecture, the CMM.31 introduces refined bridges, polished bevels, and wheel decorations, elevating both technical and aesthetic appeal.
A sweep seconds hand mounted directly on the tourbillon cage, coated with Super-LumiNova, provides precise underwater readability and ISO 6425 standards compliance.
Engineered with enhanced shock resistance up to 5 G’s and a screw-down crown, this Millésime edition is perfectly adapted for a 200m water-resistant professional diver, unlike conventional delicate tourbillons.
This makes the Superman Tourbillon Millésime CMM.31 one of the rarest combinations in watchmaking: a professional tool watch equipped with an in-house French tourbillon built for endurance.
TOOL WATCH REVOLUTION: LUXURY MEETS FUNCTIONALITY
" The Superman Tourbillon CMM.31 has been designed for purpose staying faithful to its historic codes, a true tool watch able to withstand the harshest conditions. This Millésime edition introduces elevated finishing details that distinguish it as a collector’s masterpiece: It features a Grade 5 Titanium case and Scales bracelet, a unidirectional dive bezel with domed ceramic insert, a double dome sapphire crystal, water-resistance to 200 meters, equipped with a screw-down crown while offering high anti-magnetic resistance (2,000 Gauss) and shock-resistance (5,000G) thanks to our latest in-house tourbillon caliber featuring 4 days power reserve and refined bridges and wheel decoration.
With its tourbillon built for the deep sea, this timepiece combines haute horlogerie finishing with professional dive-watch reliability, making it one of the rare tourbillon watches in the world fully compliant with ISO dive specifications.
This unique set of features is uncommon since tourbillon watches are mostly designed as watchmaking art pieces that are delicate in their utilization. This is one of the rarest tourbillons built for daily use, a luxury timepiece that is as rugged and functional as it is beautiful and refined, a tool watch in the lineage of YEMA watches. "
CHRISTOPHER BÔLE
CEO & HEAD OF DESIGN
Engineered from Grade 5 Titanium, the case and bracelet deliver the perfect balance of strength, lightness, and comfort. Renowned for its superior hardness and corrosion resistance compared to standard titanium, Grade 5 ensures exceptional durability in demanding environments while remaining hypoallergenic on the skin. The refined finishing — vertically brushed surfaces with polished bevels — enhances the geometry of the design and underscores the technical sophistication of this premium material.
HISTORIC SUPERMAN EDITION
The dial takes inspiration from the aesthetic codes of the 1960’s Superman iconic model. It features a grained black finish with applied hour markers and polished stainless steel hands aboundantly coated with Grade A BGW9 Super-LumiNova.
The new 60-second tourbillon cage boasts a sweep seconds hand which provides a mesmerizing kinetic spectacle for the wearer as it beats and turns against the partially open dial.
The unidirectional dive bezel features a high-quality domed ceramic insert with a 0–60 graduation for precise timing, while a 2.10 mm double-domed sapphire crystal ensures excellent legibility and vintage-inspired depth.
The sapphire exhibition caseback reveals the beating heart, it shows off the distinctive architecture of the CMM.31 tourbillon caliber creating a fascinating experience for the true enthusiast. The caliber’s bridges and wheels showcase meticulous haute horlogerie finishing, with finely micro-blasted surfaces, vertically brushed bevels, and chamfered edges that catch the light with elegance. Each component is decorated with care, emphasizing the architectural beauty of the movement while underscoring YEMA’s commitment to refined craftsmanship. Beyond precision, these details highlight the artistry and technical mastery embedded in every Millésime caliber.
TOURBILLON CALIBER
Invented by French horologist Abraham-Louis Breguet in 1795, the tourbillon is an advanced regulating organ present in certain high-end mechanical watches, intended to improve the precision of timepieces. It consists of a rotating cage containing the balance wheel and its hairspring, the escape wheel, the lever and the second wheel which drives it. The cage rotates 360 degrees every 60 seconds, which counteracts the effects of gravity and reduces any positional errors of accuracy. The tourbillon embodies watchmaking know-how, only a few Manufactures master the creation of this caliber masterpiece.
105 HOURS OF POWER RESERVE THANKS TO A LARGE BARREL
The CMM.31 has a single large barrel optimized to ensure a power reserve of 105 hours. Specifically manufactured for the CMM.31 by Générale Ressorts, this large barrel is off-centered in order to make enough room for the gears and the balance wheel so as to preserve a contained thickness.
FRANCO-SWISS ACCURACY
With its Swiss regulating part, the CMM.31 tourbillon is a high-precision movement ensuring high performance. The free-sprung balance wheel regulates isochronism for lasting precision and stability. In the absence of a regulator, the durability of the hairspring is increased, as is long-term precision. Adjusted in 6 positions, the CMM.31 ensures an accuracy of –3 and +7 seconds per day.
OPTIMIZED ESCAPEMENT
Interface between the gear train and the regulating organ, the escapement is the place where energy and chronometry intersect in a complex interaction. The escapement is an energy-demanding system, it alone consumes more than half of the barrels’ energy. It is the friction of the anchor pallets on the anchor which, despite their lubrication, dissipates a good part of this energy.
The CMM.31 tourbillon escapement presents notable improvements which reduce this friction thanks to an innovating and particularly sophisticated manufacturing process (LiGA technology). This advanced escapement ensures optimization of the entire mechanics, precision and longevity of the caliber components.
ANTI-MAGNETIC & SHOCK-RESISTANT
Designed for everyday life, the CMM.31 presents robust technical characteristics for a tourbillon caliber. Equipped with non-magnetic components, such as a Swiss-made non-metallic alloy hairspring, a Glucydur balance wheel with an adjustment mass made in gold and micro-components manufactured with LiGA technology materials, the CMM.31 is capable of withstanding exposures to electromagnetic fields up to 2,000 Gauss, a real feat for a tourbillon caliber.
The architecture of the tourbillon cage bridge with its free-sprung balance wheel and the shock absorbers manufactured by Kif make the CMM.31 impervious to shocks, vibrations, and acceleration up to 5,000 Gs in all directions.
PERFECTLY BALANCED PROPORTIONS
Measuring 43 mm in diameter and only 11.7 mm in thickness (remarkably slim for such a complication) with a balanced 22 mm lug span, this timepiece embodies elegance and proportion, offering a presence that is both refined and effortlessly wearable. Remarkably slim for a complication of this kind, the case ensures a refined profile while sitting naturally and comfortably on the wrist.
GRADE 5 TITANIUM SCALES SLIM BRACELET
The new YEMA Scales Slim bracelet is crafted from Grade 5 Titanium, the very same material and brushed finishing as the watch case, ensuring perfect harmony between case and bracelet. Exceptionally lightweight yet highly resistant, the bracelet offers a a sleek profile and outstanding comfort for everyday wear. Slim, robust, and refined, it enhances both the durability and the elegance of the timepiece while sitting naturally on the wrist.
The new clasp features an on-the-fly 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.
