Yema Watch: Navygraf Heritage Blue

YEMA NAVYGRAF Blue Heritage: Renaissance of the 60s icon.

The Yema Navygraf Blue Heritage is a 39mm professional diver's watch inspired by the original 60s model. Built around the Sellita SW-200 caliber, the Yema Navygraf Blue Heritage focuses on precision and robustness. A 316L steel case, screw-down crown, and solid case back ensure 200m water resistance; the Navygraf Blue Heritage remains legible and vintage thanks to the domed hesalite crystal and Super-LumiNova. With its iconic yellow hands and the addition of a date at 3 o'clock, the Yema cultivates a retro aesthetic faithful to the Navygraf lineage. On a steel bracelet with a diving extension, the Navygraf Blue Heritage offers a balanced fit (46mm lug-to-lug, 10.85mm thick, 19mm lug width).
