Skin Diver Slim Full Lume CMM.20 Limited Edition

$2,725.00

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.

CLASSIC SKIN DIVER STEEL CASE & DOUBLE DOMED SAPPHIRE CRYSTAL

Conceived as a true dive watch, the 39mm 316L stainless steel case retains all the codes of the classic Skin Diver: balanced proportions, curved 20mm lugs, an unguarded screw-down crown and a slim profile that wears effortlessly on the wrist. Vertical brushing is contrasted by polished bevels to bring just the right amount of refinement, while the thin architecture of the CMM.20 allows the case to remain just under 10mm thick without compromising its 30 BAR water resistance. Elegant on land, serious in the water.

The double-domed sapphire crystal enhances readability, adds depth to the dial and gives the watch the unmistakable old-school profile of a vintage skin diver. At the same time, it delivers the scratch resistance and everyday robustness expected from a modern mechanical dive watch.

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.
