Yema Navygraf CMM.10 Auto Black Dial 39MM Steel Bracelet Watch

COMPLETELY REDESIGNED HOUSING

This new 39 mm case in 316L stainless steel is distinguished by its proportions and brushed finishes, which contrast with the polished chamfers. The original Navygraf case has been thinned by 1.50 mm to accommodate our Manufacture CMM.10 caliber, while preserving the 46 mm horn-to-horn.
The new steel case is water-resistant to 300 meters thanks to an optimized sapphire caseback and screw-down crown.
The Navygraf CMM.10 features a 2.50 mm thick double-dome sapphire crystal, offering improved legibility, enhanced resistance and a resolutely vintage look.

ICONIC NAVYGRAF NEEDLES

The iconic exclamation mark hour markers are the distinctive signature of this model, paying homage to the vintage Navygraf model of the 1970s. Completely covered in white material, they provide a striking contrast with the monochrome dial, allowing the time to be read quickly and accurately.
The emblematic yellow Navygraf hour, minute and seconds hands add an elegant touch of color and character to this reinterpretation of this historic model.
The absence of a date is a fundamental design element that contributes to the dial's perfect symmetry and enhanced legibility.

CHRONOMETRIC PERFORMANCE

The new Navygraf CMM.10 is a modernized and improved version of the historic 1970s model. Following in the footsteps of the robust and reliable original model, we have accentuated the technical aspects of this timepiece to meet the most extreme conditions. The new Navygraf CMM.10 professional diving watch features a more elegant steel case, excellent legibility, water resistance to 300 meters, chronometric performance and a 70-hour power reserve.
