In the realm of horology, where heritage and innovation intertwine, the new Yema Skin Diver Slim CMM.20 Limited Edition emerges not merely as a timepiece, but as a considered statement. This is a watch that whispers of its iconic 1960s forebears while simultaneously roaring with modern mechanical prowess, a testament to Yema’s enduring commitment to French watchmaking excellence. Limited to a mere 500 pieces, this iteration of the Skin Diver is not simply a reissue; it is a reimagining, imbued with a groundbreaking micro-rotor movement and a design that balances vintage soul with contemporary refinement.
At the heart of this horological marvel lies the Caliber Manufacture Micro-rotor CMM.20, a movement meticulously conceived, crafted, assembled, and calibrated within Yema’s workshops in Morteau, France. This is not merely an engine; it is the very pulse of the Skin Diver Slim, a technical tour de force that elevates the timepiece to a new echelon of performance. Its near-chronometric accuracy, operating within a stringent -3/+7 seconds per day, speaks volumes about its precision engineering.

Beyond mere timekeeping, the CMM.20 boasts a substantial 70-hour power reserve, an impressive autonomy achieved through an innovative tungsten micro-rotor and a generously proportioned barrel. This is a movement designed for the demands of modern life, seamlessly blending robust performance with everyday wearability. Its slim architecture, a marvel of miniaturisation, allows for the elegant profile of the Skin Diver Slim case, demonstrating that technical sophistication and aesthetic grace can indeed coexist.

Turning our attention to the dial, we encounter a masterclass in vintage-inspired legibility. The Skin Diver Slim CMM.20 eschews fleeting trends in favour of timeless design principles. Triangular hour markers, punctuated by bold Arabic numerals, command attention, their oversized, applied construction extending towards the dial’s centre, creating depth and visual intrigue.

These markers, along with the substantial arrow-shaped minute hand, pencil-style hour hand, and lollipop seconds indicator, are generously filled with a lime-coloured Super-LumiNova, evoking the warm patina of vintage luminescence while ensuring optimal readability in low-light conditions. The dark grey dial surface acts as a sophisticated backdrop, enhancing the play of light on the polished steel markers and hands, further amplifying the dial’s depth and allure.

Encircling this captivating dial is the bezel, a defining feature of the Skin Diver Slim, imbued with a sought-after “faded ghost” aesthetic. Crafted entirely from sapphire, its unidirectional rotation and 0-60 scale, complete with a Grade A Super-LumiNova marker at 12 o’clock, pay homage to the functional imperatives of professional diving watches. The “faded ghost” appearance, achieved with meticulous artistry, imbues the bezel with a sense of seasoned character, a subtle nod to the watch’s lineage while retaining a contemporary edge.


Flipping the Skin Diver Slim reveals a sapphire exhibition case back, a window into the captivating mechanics of the CMM.20 micro-rotor caliber. This is an invitation to appreciate the intricate dance of gears and springs, a rare glimpse into the heart of a truly exceptional movement. Each case back is individually engraved with a unique serial number, mirrored on the accompanying 5-year warranty card, emphasizing the limited and exclusive nature of this timepiece.

Completing the ensemble is the reimagined Scales bracelet, a Yema signature, slimmed down to harmonize seamlessly with the case’s refined profile. Its fully brushed finish provides a sophisticated continuity, while the double-security folding clasp, equipped with a dive extension, underscores the watch’s inherent versatility, ready for both urban exploration and aquatic adventures. The Yema Skin Diver Slim CMM.20 Limited Edition is more than a watch; it is a legacy reborn, a synthesis of vintage charm and modern horological innovation, destined to captivate discerning collectors and enthusiasts alike.
