ULTRA-LEGIBLE SKIN DIVER DIAL

The uniqueness and singularity of the dial's triangular, angular indexes, combined with the integration of Arabic numerals, offer excellent legibility. The applied indexes are also slightly oversized, tapering towards the center of the dial to enhance the arrow-shaped minute, pencil-shaped hour and lollipop-shaped second hand.

All these elements are finished in flave-colored Super-LumiNova, a reference to vintage models.

The dial features a light brushed finish that accentuates the play of light of the polished steel applied hour-markers and hands on the dial.

CALIBRE MANUFACTURE MORTEAU 20

Calibre entirely designed and developed by YEMA. Components (bridges and plates) manufactured directly in our YEMA workshops in Morteau, including assembly, adjustment and testing.

SAPPHIRE BEZEL & PUSH-TO-UNLOCK BEZEL MECHANISM

The sapphire bezel perfectly matches the dial, creating a unified, elegant aesthetic.

The new bezel-locking mechanism marks a genuine evolution, both in terms of engineering and handling, while preserving the iconic identity of the Superman.

Unlike the original system, where a part was placed above the bezel and held in place by the crown, this new mechanism is fully integrated under the bezel and is easy to use. This significant improvement offers a streamlined profile and a modern, minimalist design, while preserving the Superman's professional features.

The bezel is now locked by default, preventing accidental rotation during immersion or everyday use. To turn the bezel, simply apply slight pressure to it to momentarily disengage the locking mechanism. By holding it down, the bezel can be rotated freely in either direction, and then simply releasing the pressure locks it instantly.

SAPPHIRE CASEBACK

The caseback features a transparent sapphire crystal caseback, allowing you to admire our Manufacture CMM.20 caliber in all its splendor, while preserving its 300-meter water-resistance.

The CMM.20 benefits from a "côte de Genève" soleillage treatment that seems to emanate from the micro-rotor, perfectly highlighting it. The play of light that accompanies the movement's rotation creates a mirror effect, giving theimpression that the surface is in perpetual motion.

NEW SCALES SLIM STAINLESS STEEL BRACELET WITH MICRO ADJUSTMENT

The emblematic YEMA Scales steel bracelet from the 1960s has been slimmed down by 0.40mm to blend harmoniously with the Skin Diver's slimmer case.

This new Scales Slim bracelet tapers progressively from 4mm to the buckle, adapting naturally to the shape of the wrist. It features a fully brushed finish, offering visual continuity with the brushed case.

The new buckle is equipped with a quick-adjust mechanism, ideal for adapting to your needs, or to compensate for variations in wrist size, particularly during changes in temperature and heat. The bracelet can now be adjusted instantly, without removing the watch or using tools.

Inside the buckle, the last maillon the bracelet is mounted on a thin, precision-machined internal sliding blade. This thin blade allows fluid movement back and forth, offering a progressive adjustment of up to 6 mm in 1 mm increments. For added security, a double release system consisting of two push-buttons unlocks the blade, allowing the bracelet to be adjusted to the desired length. The mechanism is fully integrated into the buckle, preserving aesthetics and protecting it from dust and shock.

STEEL CASE SKIN DIVER

Designed with the characteristics of a professional diver's watch, the 39.5 mm 316L stainless steel case (47 mm from lug to lug) features 20 mm curved lugs and brushed finishes contrasting with polished bevels.

Instantly recognizable thanks to the absence of a crown guard, the case houses our CMM.20 micro-rotor caliber, while preserving 300-meter water resistance thanks to its sapphire caseback and screw-down crown.

DOUBLE-DOME SAPPHIRE CRYSTAL

The Skin Diver features a 2.20 mm thick, double-dome sapphire crystal, resistant to shocks and scratches. The domed shape gives it a very unique, resolutely vintage look, offering enhanced legibility.

SUPER-LUMINOVA GRADE A

The hour-markers, hands and 12 o'clock marker on the bezel are coated with Super-LumiNova Grade A for perfect legibility even in the dark.
