When it comes to military tool watch provenance, few relationships run as deep as YEMA’s historic partnership with the French armed forces.
As the Marine Nationale celebrates 400 years of naval heritage, the French watchmaker has unveiled a mission-driven dive watch inspired by the silent guardians of the abyssal depths: the Yema Navygraf Barracuda CMM.20 Limited Edition.
Named in honor of France’s next-generation Barracuda nuclear attack submarine program, this 400-piece limited edition reinterprets the brand’s 1970s Navygraf silhouette through a stealthy, high-tech lens.
Priced at £2040, it fuses genuine submarine operational protocols with YEMA’s manufacture micro-rotor movement.
Submarine Protocol & Forged Carbon Aesthetics
At first glance, the watch commands attention through its high-pressure forged carbon dial and matching unidirectional bezel insert.
Far more than a cosmetic choice, the compressed carbon fibers deliver exceptional shock resistance and lightness, while ensuring no two dials feature the exact same marbled pattern.
The 120-click bezel incorporates a 20-minute countdown sector highlighted in vibrant tactical red.
This specific 20-minute window directly mirrors standard submarine synchronization protocols, allowing crew members to track critical timed operational maneuvers at a single glance.
“To maintain split-second legibility inside the dark hull of a submarine, matte white applied indexes and hands are paired with a bold, red-outlined minute hand, all loaded with Super-LumiNova C1 Grade A for intense low-light glow.”
Matching the tactical red countdown scale is the bright red “BARRACUDA” text at 6 o’clock—a crisp pop of color that echoes military onboard instrument gauges against the dark carbon backdrop.
The “Forces Sous-Marines” Red Sapphire Caseback
Flipping the 39mm 316L stainless steel case reveals one of the most thematic details in modern tool watch design: a red-tinted sapphire exhibition caseback.
This is a direct nod to the ambient red lighting used aboard nuclear attack submarines (SSNs). Under combat or night operations, submariners switch to red illumination because the human eye can read instruments without losing its natural adaptation to total darkness—a vital necessity for periscope observation or night surfacing.
Laser-engraved at the center of the red crystal is the official emblem of the French Navy Submarine Forces (Forces Sous-Marines), framing the dark, industrial movement beneath.
Slim Proportions & Manufacture CMM.20 Mechanics
Despite its rugged military pedigree and 300-meter water resistance, the watch maintains remarkably sleek proportions.
The case measures a comfortable 39mm in diameter, 46mm lug-to-lug, and slimmed down to under 10mm in case thickness (excluding its vintage-inspired 2.5mm double-domed sapphire crystal).
* Case: 39mm 316L Stainless Steel (Under 10mm Case Thickness / 46mm Lug-to-Lug)
* Dial & Bezel: Forged Carbon with Tactical Red 20-Minute Sector
* Movement: In-House Manufacture Micro-Rotor Calibre CMM.20
* Power Reserve: 70 Hours (28,800 vph / 4 Hz)
* Crystal: 2.50mm Double-Domed Sapphire Crystal
* Limitation: 400 Pieces Worldwide
This comfortable wrist presence is made possible by YEMA’s in-house manufacture micro-rotor movement, the Calibre CMM.20 (Calibre Manufacture Morteau 20).
Featuring an ultra-thin architecture, a bi-directional tungsten micro-rotor, and a steady 28,800 vph frequency, the movement delivers an impressive 70-hour power reserve with chronometric precision.
