Yema Navygraf Slim Watch CMM.20 Auto Black Dial Leather Bracelet 39MM

NAVYGRAF SLIM CMM.20
Equipped with the CMM.20, our micro-rotor manufacture caliber, this reworked version of the historic Navygraf model features a slimmer 39 mm case with a polished/brushed bevelled finish and a minimalist sapphire bezel. White applied hour-markers contrast perfectly with the black lacquered dial. This new, slimmer and more versatile interpretation of the Navygraf fits all wrists and styles while retaining its professional features, and is water-resistant to 300m.

FRENCH MANUFACTURE CALIBER
Caliber designed and developed by Olivier Mory. Micro-components manufactured directly in our workshops in Morteau, including assembly, adjustments and controls.

ULTRA-THIN MICRO-ROTOR CALIBER
Thanks to its modern architecture, the micro-rotor caliber is only 3.70 mm thick, enabling it to be used on much thinner cases.

ACCURACY OF -3/+7 SECONDS
Optimized mechanical precision with chronometer-like performance (COSC). Swiss regulating organs in non-magnetic alloys.

POWER RESERVE 70H
Increased power reserve thanks to a large barrel and an innovative high-density tungsten micro-rotor for optimized winding.

COMPLETELY REDESIGNED ULTRA-THIN 300-METER CASE
The new 39 mm case in 316L stainless steel features optimized proportions and brushed finishes contrasting with polished chamfers.
The original Navygraf steel case has been slimmed down by almost 3 mm to just 9.5 mm to accommodate our CMM.20 micro-rotor caliber.

The new steel case is water-resistant to 300 metres thanks to an optimized sapphire caseback and an improved screw-down crown.

MANUFACTURE FRANÇAISE" GLOSSY DIAL
All the words on the dial are now in French, and we wanted to add the signature MANUFACTURE FRANÇAISE at 6 o'clock in reference to our in-house manufacturing and local production of components.

To design our glossy dials, several coats of lacquer are carefully applied at regular intervals according to different drying times.

This special treatment, which gives the black dial a deep, clean look, also accentuates the play of light and amplifies the reflections of the two convex faces of the double-domed sapphire crystal.

NEW FACETED STEEL HANDS AND APPLIED HOUR MARKERS
The polished hour-markers, circled and raised on the dial, blend perfectly with the faceted polished steel hour and minute hands. Navygraf 's second hand retains its original yellow color, as well as the distinctive Navygraf lettering at 12 o'clock.

All needles are treated with grade A Super-LumiNova.

GRADE A SAPPHIRE & SUPER-LUMINOVA BEZEL
The rotating bezel stands out both for its minimalist design and for the quality of its finish. Its sapphire surface gives it a glossy appearance in perfect harmony with the glossy dial and contrasting with the brushed finish of the case. The redesigned bezel features unidirectional rotation, a simplified 0-60 scale and a luminescent marker at 12 o'clock treated with Super-LumiNova Grade A, an essential feature for a professional diving watch.

DOUBLE-DOME PLUS SAPPHIRE CRYSTAL
Navygraf Slim features a 2.00 mm double-dome sapphire crystal that is both scratch- and impact-resistant. Its curved shape gives it a unique, resolutely vintage look, while its two convex sides enhance legibility and increase water resistance to 300 meters.

000/200 LIMITED EDITION CASEBACK SAPPHIRE CRYSTAL
The caseback features a sapphire crystal, allowing the Manufacture CMM.20 caliber to be admired in all its splendor, and preserving its 300-meter water-resistance.

Each base is engraved with a unique serial number, also displayed on the 5-year warranty card, and the corresponding limited edition number on a total of 200 pieces.
