Watch Navygraf Marine Nationale CMM.10 White Bezel 21.14.75.SN

The Watch

Founded in 1948 in Morteau, France, Yema was born from the vision of Henry Louis Perret. The brand quickly made a name for itself with its dive watches and chronographs, combining ruggedness with precision. Among its iconic creations, the Yema Superman established itself as a must-have classic for watch enthusiasts. With a commitment to innovation and artisan craftsmanship, this French brand offers timepieces equipped with state-of-the-art movements and built from robust materials for reliable everyday use. Drawing on its watchmaking expertise, Yema fuses refined aesthetics, high precision, and captivating style to bring the Navygraf Marine Nationale CMM.10 white bezel watch to life. This model, developed in partnership with the Marine Nationale, is designed for sailors on missions deployed across the globe. It features a brushed and polished 316L stainless steel case measuring 46 mm in length, 39 mm in diameter, and 11 mm in thickness, with a dive bezel. Unidirectional, it is fitted with a white sapphire insert and features Arabic numeral indices at 15-minute intervals, all luminescent and treated with grade A Super-LumiNova BGW9. It surrounds a double-dome sapphire crystal 2.50 mm thick, protecting the dial against everyday impacts. The dial features hour markers operated by the grey, grooved, screw-down crown at 3 o'clock, embossed with the Marine Nationale anchor insignia in relief for a confident grip. Finally, this model features a engraved screw-down case back providing water resistance to 30 ATM, fitted with a sapphire crystal to admire the movement in all its glory.

The Dial

This dial is inspired by the Navygraf II from the 1970s. It features a blue background evoking the Marine Nationale's colors, with the unit's name inscribed near 6 o'clock. Enhanced by a matte finish for a clean, uncluttered look, it features a minute track with printed geometric indices for hour reading. At its center, three faceted stainless steel hands ensure smooth and precise timekeeping. The slender matte yellow seconds hand counts the elapsed seconds, the long hand marks the minutes, and the short hand points to the hours. For optimal legibility even in complete darkness, a grade A Super-LumiNova BGW9 treatment is applied to the white hands and hour indices. The outer edge displays the country of manufacture, water resistance rating, and movement type. Finally, below the 12 o'clock index trio, the brand places its logo alongside the collection name as its signature.

The Movement

This timepiece is powered by a robust and reliable automatic movement - specifically the CMM.10 caliber, measuring 28 mm in diameter and beating at a frequency of 28,800 vph (4Hz). It is composed of 208 components, including a bidirectional rotor and 27 jewels to reduce friction. It also features a glucydur balance wheel, galvanic decoration processes, and a large Nivaflex mainspring barrel. Thanks to its non-magnetic alloys and Incabloc shock absorbers, it provides resistance against magnetic fields and shocks. This movement delivers a chronometric accuracy of -3/+5 seconds per day and a power reserve of approximately 70 hours.

The Band

This timepiece comes with two strap options selectable via the dropdown menu. Both feature a lug width of 19 mm and will complement your look for any occasion.

This dive bracelet is crafted in brushed and polished 316L stainless steel, giving it a sharp, refined look. Its links contour the wrist with ease, and its silver tone pairs effortlessly with your other accessories. Sturdy yet comfortable for everyday wear, it features a double-safety deployant clasp with an extension for quick and easy adjustment over a dive suit.

The second strap is a Marine Nationale band. Of NATO type, it is inspired by the handmade straps crafted by French Navy combat divers in the 1970s. Elastic and lightweight, it ensures comfortable wear in any conditions. It features a woven finish in blue with a centered white stripe running along its length, adding a sharp touch to any look. It wraps the wrist with ease, and its Velcro clasp bearing the MNF logo lets you adjust the fit to your preference.

Water Resistance

This model offers water resistance to 30 atmospheres, or 300 meters. Whether you're playing at 20,000 leagues under the sea in the pool with the kids or tackling serious professional scuba diving, this watch has you covered. The deep and its creatures don't stand a chance - you're ready! The Ocarat team wishes you a fantastic dive, with one final tip: don't operate the pushers or crown during descent!
