Google translated - In 2021, the Navygraf de Yema will therefore be dressed in the colors of the French Navy: this new watch features a matt blue dial and proudly displays the French Navy logo placed at 6 o'clock and the anchor of the braids embossed on the crown.
It is available in four versions: available in quartz (waterproof 200 meters) and automatic (39mm, waterproof to 300 meters), the model will also be offered with the GMT function in an edition limited to 1,000 pieces. The Navygraf Marine Nationale will also see the light of day in a 34mm version - 100 meters waterproof - to adapt to the female wrist. The timepieces are delivered in a collector's box and will be available for pre-order from May 6, 2021 on yema.com.
Note that by purchasing a Navygraf Marine Nationale, a donation is paid to the social works of the Navy. A percentage of the price of each watch is donated to the foundation.
