Superman Tourbillon CMM.31 - Ltd Ed 100pcs

Invented by the legendary French horologist Abraham-Louis Breguet in 1795, the tourbillon remains one of the most prestigious complications in mechanical watchmaking. Designed to counteract the disruptive effects of gravity on a timepiece's accuracy, this masterwork of engineering houses the balance wheel, hairspring, and escapement within a rotating cage that completes a full 360-degree revolution every 60 seconds. Mastering the creation of such a delicate regulating organ is a feat achieved by only a handful of Manufactures, serving as a definitive hallmark of horological expertise and technical "know-how."

With the debut of the Superman Tourbillon CMM.31, YEMA inaugurates its prestigious "Millésime Editions"—an annual series dedicated to showcasing the absolute pinnacle of the brand's in-house capabilities. The "Millésime" designation represents the very best of YEMA: a premium, handcrafted, and highly limited timepiece that honours the legacy of French horology. 

Yema Superman Tourbillon CMM.31 Limited Edition

For 2025, YEMA has reimagined its most iconic professional diver, the 1963 Superman, by equipping it with a Manufacture tourbillon calibre. The result is a bold fusion of high-end finishing and robust tool-watch specifications, marking a sophisticated new chapter in YEMA's pursuit of excellence.

The Superman Tourbillon CMM.31 is engineered from Grade 5 Titanium, a premium material selected for its superior hardness and corrosion resistance compared to standard titanium. This ensures the 43mm case and the iconic Scales bracelet remain incredibly lightweight and hypoallergenic without compromising on the rugged durability required for a professional diver.

The finishing details underscore this technical sophistication, featuring expert vertical brushing contrasted by polished bevels that highlight the watch's geometric lines. With a refined profile of 11.7mm in thickness and a 50mm lug-to-lug, the Superman Tourbillon delivers a commanding yet comfortable presence on the wrist.

Historic Superman edition

While most tourbillons are delicate masterpieces reserved for dress watches, YEMA has engineered the CMM.31 to thrive in demanding environments. This timepiece is a rare exception in the horological world, featuring a screw-down crown and a unidirectional dive bezel with a high-quality domed ceramic insert for precise timing.

Built to be fully compliant with ISO dive specifications, it boasts a 200m water resistance and enhanced shock resistance of up to 5,000 Gs. This unique combination of high-end finishing and professional-grade reliability ensures that the Superman Tourbillon is as capable in the deep sea as it is refined on land.

Protected by a double-domed sapphire crystal, the dial draws deep inspiration from the iconic 1960s Superman, featuring a sophisticated grained black finish that serves as a textured backdrop for the applied hour markers and polished steel hands. To ensure professional-grade legibility, these elements are abundantly coated with Grade A BGW9 Super-LumiNova, providing a sharp, long-lasting glow in low-light environments. 

Titanium grade 5 excellence

The undeniable centerpiece of the dial is the 60-second tourbillon cage, visible through a partially open aperture that creates a mesmerizing kinetic spectacle for the wearer. In a fusion of high-end aesthetics and technical utility, a sweep seconds hand is mounted directly onto the rotating cage; also coated in Super-LumiNova, this hand ensures the precise underwater readability required to meet stringent ISO 6425 standards.

Traditionally, the tourbillon has been a fragile complication reserved for the controlled environment of a dress watch. The CMM.31 calibre, however, completely breaks this paradigm. Developed by renowned watchmaker Olivier Mory and manufactured by the YEMA team in Morteau, France, this movement is a sophisticated evolution of the proven CMM.30 architecture. It delivers an extraordinary 105-hour power reserve—nearly four full days—while beating at a steady 21,600 bph (3Hz). Equipped with a Swiss regulating organ and adjusted in six positions to ensure high-precision accuracy of -3 to +7 seconds per day, the CMM.31 is as much a high-performance engine as it is a work of art.

The sapphire exhibition caseback reveals the movement's architectural beauty, showcasing a level of Haute Horlogeriefinishing rarely seen in a professional diver. The bridges and wheels feature a meticulous combination of micro-blasted surfaces, vertically brushed bevels, and polished chamfered edges that elegantly catch the light. Every component is decorated with an eye for detail, emphasizing the technical mastery and French craftsmanship embedded in the "Millésime" series. By balancing this refined aesthetic with a robust build, YEMA has successfully transformed the tourbillon into a complication that can withstand the rigours of the deep sea without losing its soul.

Grade A Super-Luminova

The 22mm Scales slim bracelet is crafted from the same high-performance Grade 5 Titanium as the case, ensuring a seamless, monochromatic harmony and a refined brushed finish. Exceptionally lightweight yet significantly more resistant to the elements than traditional steel, the bracelet offers a sleek, robust profile that sits naturally on the wrist for outstanding everyday comfort.

This sophisticated design is paired with a newly engineered clasp featuring an on-the-fly adjustment mechanism, allowing for instant, tool-free micro-adjustments. Whether adapting to physical activity or changes in temperature, the wearer can achieve a perfect fit in seconds, perfectly balancing the watch's professional dive heritage with modern ergonomic luxury.

While most tourbillons are treated as delicate works of art, the Superman Tourbillon Millésime CMM.31 is engineered for the rigours of the real world. It represents one of the rarest combinations in watchmaking: a high-end luxury timepiece that is as rugged and functional as a professional diving tool. By housing a sophisticated French manufacture tourbillon within a shock-resistant, titanium architecture, YEMA has created a rare masterpiece of endurance designed for the collector who demands both artistic soul and absolute reliability. Strictly limited to just 100 numbered timepieces, this Millésime edition stands as a definitive testament to the modern evolution of French horological excellence.
