Yema Skin Diver Slim Bronze CMM.20 Limited Edition

Supercharged with a micro-rotor Manufacture caliber, the Skin Diver Slim Bronze CMM.20 Limited Edition is the modern interpretation of the iconic skin divers released by Yema in the 1960’s. Rugged, yet stylish.

Ultra legible skin diver dial

The complex dial layout provides a distinctive design element and excellent legibility by showcasing triangular-shaped hour markers complete with Arabic numerals. The oversized applied markers extend into the center of the dial and are matched with a large, arrow-shaped minute hand, a long, pencil-shaped hour hand, and lollipop for the seconds.

All the elements are generously filled with vintage-inspired, lime-coloured Super-LumiNova and outlined in gilt finish. Simply balanced, bold lumed markers and broad hands complement each other entirely.

The hour markers, hands and bezel pipe are coated with Grade A Super-LumiNova for perfect readability even in the dark.

The enamel dial base has a dark grey surface in matte finish, reinforcing the old-school look, and contributing to accentuate the play of light of the gilt raised markers and hands against the dark dial.

“Faded ghost” sapphire bezel

The rotating bezel stands out for its vintage-inspired “faded ghost” look. It is entirely made of sapphire and is in perfect harmony with the dark grey dial and the brushed finish of the case. This redesigned bezel features a unidirectional rotation, a 0-60 scale, and a luminescent marker at 12 o’clock treated in Grade A Super-LumiNova, which constitute essential features for professional diving watches.

Classic skin diver bronze case

Conceived as a professional dive watch, the 39mm bronze case (47mm lug-to-lug) stands out with its 20mm curved lugs and brushed finishes in contrast with the polished bevels.

Instantly recognizable by its unguarded crown and with a contained thickness of just 10mm, the steel case has been slimmed down to accommodate our CMM.20 micro-rotor caliber, while preserving a 30 BAR water resistance thanks to the sapphire exhibition case-back and the screw-down crown.

As it’s exposed to air, moisture, and everyday wear, the bronze case will gradually develops a distinctive patina, giving each watch a uniquely lived-in character. Warm, tactile, and deeply nautical in spirit, bronze offers a natural, ever-changing finish that makes no two cases look exactly alike.

000/200 limited edition sapphire exhibition case-back

Luxury watches can inspire for a variety of reasons. It’s not only the design and the style of the timepiece but also the technical aspects of a fine timepiece that can really blow watch enthusiasts away. The sapphire exhibition case-back is an elegant feature for those who enjoy taking a look at the inner workings of their mechanical timepieces, in this case it allows wearers to catch a glimpse into the inner intricacies of the Manufacture micro-rotor caliber CMM.20, a rare caliber worthy of showcasing.

Each case-back is engraved with a unique serial number, also displayed on the 5-year warranty card, and the corresponding Limited Edition number out of a total of 200 timepieces.
