Watch Yema Meangraf Y60 Auto Black Dial Bracelet Leather 39MM
IN-HOUSE CALIBER YEMA2000
The second-generation YEMA2000 in-house Caliber is powered by optimized components offering slightly higher performance than competing calibres, offering a daily drift of +/- 10 s/d and a power reserve of 42 hours.
SAPPHIRE BEZEL
The two-way diving bezel of the MEANGRAF is made of sapphire, an extremely durable and scratch-resistant material. The aluminum insert underneath the sapphire offers Super-Luminova indexes for easy reading of its dive time in low-light conditions.
ORIGINAL NEO-VINTAGE DIAL
Inspired by vintage MEANGRAF models, this original dial design is instantly recognizable with its slightly centred hour markers, 24-hour flange, as well as the famous red vertical stripes matching the second hand.
CONTOURED HOUSING
The MEANGRAF case is arguably the most complex case made by YEMA. The integrated bezel is a design challenge due to its engineering but also to its primary functionality (a diver must be able to easily handle the countdown bezel with diving gloves). The 39 mm case, made of 316L stainless steel, has been specifically designed to perfectly integrate the rotating bezel and gives the impression that these two parts form a single piece with a unique design. A unique design for a watch with professional functions.
HELIUM VALVE
Due to the complex structure of the case and its integrated bezel, our watchmakers proposed to implement a helium escape valve in order to achieve the standard 300m/990ft water resistance of diver's watches YEMA. This feature makes the MEANGRAF a professional diver's watch.
TIN BOTTOM
Developed to withstand heavy use, the historic coat of arms of YEMA Struck with a hydraulic press with an embossed polished/brushed effect.
DOUBLE DOME SAPPHIRE CRYSTAL
The MEANGRAF features a high-quality 2.60 mm thick double-domed sapphire crystal, offering increased scratch resistance (Mohs scale 9 – Diamond 10) and a decidedly vintage look while making the dial easier to read in an aquatic environment. This type of double-domed glass is mainly found on high-end watches because the construction of its two convex sides requires 3x more sapphire material.
SUPER-LUMINOVA®
The hands, indexes and indexes of the bezel are coated with SUPER-LUMINOVA® BGW9, offering perfect legibility in the dark.
