Military watch YEMA Navygraf French Navy CMM.10
Starting from 1.690 €The YEMA Navygraf French Navy CMM.10 is a French automatic military dive watch designed in the spirit of military tool watches. Developed around YEMA’s collaboration with the French Navy, it combines a 39 mm stainless steel case, 300-metre water resistance, a unidirectional sapphire bezel and a matte blue dial inspired by the 1970s Navygraf II. This version also marks an important technical step forward thanks to the Manufacture Morteau CMM.10 calibre, a French automatic movement offering a 70-hour power reserve and an announced accuracy of -3/+5 seconds per day. Available with a blue or white bezel, it blends maritime heritage, local manufacturing and genuine dive-watch credibility.
Military dive watch YEMA Navygraf French Navy CMM.10
YEMA is one of the French watch brands most closely associated with dive watches, sports watches and instruments designed for demanding environments. The Navygraf collection belongs to this history, with a design born in the 1970s, defined by graphic indexes, strong legibility and an immediately recognisable diver’s silhouette. The Navygraf French Navy CMM.10 takes this heritage and brings it into a more technical, more manufacture-driven and more institutional dimension.
This watch was designed and developed jointly with the French Navy, giving it a clearly military and maritime identity. It does not rely on excessive decorative effects: the matte blue dial, yellow seconds hand, French Navy signature at 6 o’clock and crown decorated with the anchor from the French Navy stripes create a coherent, understated and recognisable whole. The choice of a no-date dial reinforces symmetry and gives this diver a cleaner, more tool-watch-oriented face.
Its positioning also relies on serious specifications for a modern dive watch: 316L stainless steel case, unidirectional dive bezel, sapphire insert, Grade A BGW9 Super-LumiNova, steel bracelet with diving extension and 300-metre water resistance. The CMM.10 calibre adds real horological value with its 70-hour power reserve, 27 jewels, 208 components and architecture designed for stability, precision and shock resistance. This Navygraf therefore becomes a complete French military dive watch, more ambitious than the more accessible versions in the collection.

The military YEMA Navygraf French Navy CMM.10 watch
The YEMA Navygraf French Navy CMM.10 takes the most recognisable codes of the Navygraf collection and adapts them to a more modern and more technical dive watch. Its 39 mm case remains compact, balanced and easy to wear every day. It keeps a true diver’s presence, without an excessive diameter. The 316L stainless steel receives a vertically brushed finish, completed by polished bevels, giving the watch an appearance that is both utilitarian and refined. This approach suits its positioning well: a military dive watch that can be worn at sea, during sports use or in a more urban setting.
The matte blue dial is directly inspired by the 1970s Navygraf II. The printed indexes, white faceted steel hands and matte yellow seconds hand reinforce the visual identity of the model. The French Navy signature at 6 o’clock recalls the official collaboration, while the absence of a date preserves a very appreciable symmetry on a tool watch. The two available references differ only by the bezel colour: blue for a more classic continuity with the dial, white for a more contrasted look. In both cases, the watch retains the same spirit: a legible, robust and historically rooted French diver.
A French diver powered by the Manufacture Morteau CMM.10 calibre
The main evolution of this Navygraf French Navy comes from its movement. The Manufacture Morteau CMM.10 calibre is a 28 mm automatic movement designed to offer an ambitious French alternative to traditional three-hand calibres. It runs at 28,800 vibrations per hour, or 4 Hz, and provides a 70-hour power reserve. This autonomy is achieved thanks to a large barrel and allows the watch to be left aside for more than two days without needing to be reset immediately. YEMA also announces an accuracy of -3/+5 seconds per day, a very interesting figure in this range.
The movement architecture also strengthens the technical interest of the model. The CMM.10 uses a bidirectional oscillating weight, 27 jewels, 208 components, a Glucydur balance wheel, a Nivaflex barrel spring and a double-cone Incabloc shock protection system. Non-magnetic alloys help support movement stability, while the traversing balance bridge contributes to better support of the regulating organ. The sapphire caseback allows this calibre to be observed, while preserving 300-metre water resistance. With its unidirectional sapphire bezel, Grade A BGW9 Super-LumiNova and steel bracelet with diving extension, this YEMA is not just a tribute: it claims genuine technical coherence.
