Yema Watch: Navygraf Heritage Black

YEMA NAVYGRAF Black Heritage: Rebirth of a 60s icon.

The Yema Navygraf Black Heritage is a 39 mm professional diver's watch inspired by the original 60s model. Designed around the Sellita SW-200 caliber, the Yema Navygraf Black Heritage focuses on precision and robustness. A 316L steel case, screw-down crown, and solid case back ensure 200m water resistance; the Navygraf Black Heritage remains legible and vintage thanks to its 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 Black Heritage offers a balanced fit (46 mm lug-to-lug, 10.85 mm thickness, 19 mm lug width).
