000/400 LIMITED EDITION
A NEW LIGHT ON THE SKIN DIVER
Powered by our Manufacture micro-rotor caliber, this Limited Edition is the boldest luminous expression of YEMA’s 1960s Skin Diver yet. Limited to 400 pieces, it combines the ultra-slim 39mm steel case and CMM.20 with a full-lume white dial paired with a white luminous FKM strap for a look that is as graphic in daylight as it is striking after dark. Rugged, distinctive and unmistakably vintage in spirit.

FULL-LUME SKIN DIVER DIAL
The dial has been conceived as a light source in its own right. Its white full-lume surface delivers immediate legibility, while the applied hour markers are framed in matte black and paired with black hands for crisp daytime contrast. The classic Skin Diver display remains intact, with its broad arrow minute hand, slimmer hour hand and lollipop seconds hand preserving the unmistakable personality of the collection. Clean black printed text and minute markers keep the composition sharp, balanced and easy to read.

BLACK SAPPHIRE DIVE BEZEL
Framing the dial is a flat black sapphire dive bezel that reinforces the watch’s monochrome tool-watch character. Its bright scale and luminous pearl at 12 o’clock create a strong contrast against the white dial, while the unidirectional dive function preserves the professional spirit of the Skin Diver.

000/400 LIMITED EDITION SAPPHIRE EXHIBITION CASE-BACK
The sapphire exhibition case-back reveals the Manufacture CMM.20 and highlights the technical refinement behind the watch’s slim profile. Each watch is individually numbered 000/400, reinforcing the collector appeal of this limited edition while connecting every piece to its personalised warranty card.

WHITE LUMINOUS FKM VITON® SCALES STRAP
Developed specifically for this edition, the white FKM scales strap extends the full-lume concept beyond the dial and onto the wrist. Flexible, resilient and comfortable in demanding conditions, it gives the watch a more exclusive and contemporary edge while remaining fully aligned with its diving purpose. A brushed stainless steel buckle completes the look with the same restrained, functional elegance as the case.
Skin diving (or free-diving) became very popular in the mid-20th century which led to a wide variety of utilitarian watches that were designed to be used during recreational diving. Water resistant skin diver watches were instantly recognizable: They featured a slimmer and smaller case than the professional dive watches, as well as unguarded crown, making them more ergonomic and easy to wear. On top of that, they were stylish enough to feel appropriate out of the water too, offering a dressier and more refined approach, some sort of rugged elegance.
GRADE A C1 SUPER-LUMINOVA
The hour markers, hands and bezel pipe are coated with Grade A C1 Super-LumiNova for perfect readability even in the dark.
-3/+7 SECONDS ACCURACY
Near chronometric performance and high resistance to magnetic fields and shocks.
70 HOURS POWER RESERVE
Enhanced power reserve thanks to innovating Tungsten micro-rotor and a large barrel.
LOCAL PRODUCTION
Over the past few years, YEMA has made significant investments aimed at insourcing a good part of its production and constantly improving the quality of its manufacturing processes by implementing latest equipment as well as expanding and modernising its workshops and production lines. In addition, YEMA now works with new local partners in France and Switzerland within a range of 72km of its workshops, to secure a more responsible and higher quality production.

A DYNAMIC REGIONAL WATCHMAKING ECOSYSTEM
YEMA workshops are based in Morteau, the cradle of French watchmaking, a few steps from the Swiss watchmaking region. This cross-border watchmaking community concentrated along the Jura mountains has gradually transformed into a true regional ecosystem recognized as Intangible Cultural Heritage by the UNESCO in 2020.
