YEMA Navygraf Heritage Automatic 39mm (Ref. YNAV25-AM)

The YEMA Navygraf Heritage is a vintage-inspired French dive watch that faithfully recreates the distinctive character of the original Navygraf models of the 1970s while incorporating a reliable modern Swiss automatic movement. With its matte dial, signature yellow hands, iconic “exclamation point” hour markers, and matching vintage-style dive bezel, the Navygraf Heritage delivers unmistakable retro tool-watch personality.

This pre-owned example features YEMA’s redesigned 39mm stainless steel case, offering classic proportions that are exceptionally versatile on the wrist. At only 10.85mm thick with a compact 46mm lug-to-lug measurement, the Navygraf Heritage maintains a slim profile despite offering genuine dive-watch capability and 200 meters of water resistance.

One of the defining characteristics of this generation is its double-domed Hesalite crystal. Rather than using sapphire, YEMA intentionally chose Hesalite to reproduce the softer reflections and warm visual character associated with vintage tool watches. The effect complements the matte dial and bold yellow hands beautifully, reinforcing the watch’s authentic 1970s-inspired aesthetic.

The dial retains some of the Navygraf’s most recognizable design elements, including its distinctive hour markers and bright yellow hands for excellent legibility. This updated Heritage version also reintroduces a date complication, adding everyday practicality without taking away from the clean vintage-inspired presentation.

Surrounding the dial is a unidirectional dive bezel with an epoxy insert and 60-minute scale. The triangular marker at 12 o’clock is treated with Grade A Super-LumiNova®, while the hands and hour markers receive the same luminous treatment for strong visibility in low-light environments.

Inside is the proven Sellita SW200-1 Swiss automatic movement, featuring 26 jewels, a frequency of 28,800 vibrations per hour, and approximately 38 hours of power reserve. The watch is assembled in YEMA’s workshops in France.

The YEMA Navygraf Heritage offers a particularly compelling combination of authentic 1970s dive-watch styling and modern mechanical reliability. Rather than simply giving a contemporary diver a vintage color palette, YEMA incorporates details such as the double-domed Hesalite crystal, epoxy bezel insert, distinctive yellow hands, and signature Navygraf hour markers to recreate the character of the original watch.

Its dimensions are equally appealing. The 39mm diameter, 46mm lug-to-lug, and slim 10.85mm profile provide excellent everyday wearability, while the screw-down crown and 200-meter water resistance ensure that the Navygraf retains genuine sports-watch capability.

Powered by the reliable Swiss Sellita SW200-1 and assembled in YEMA’s French workshops, the Navygraf Heritage is an excellent choice for collectors looking for a mechanical diver with French watchmaking heritage, distinctive vintage character, practical dimensions, and proven Swiss mechanics.
