My view

Le chocolat et l’orange, l’audace seventies

This Bullead chronograph houses a Valjoux 7750 caliber from the ’70s.

Highly prized by collectors for its robustness, it stands out for its quality, reliability and vintage look.

The model on offer dates from the ’70s (circa 1975): it is a Swiss DIFOR chronograph with three registers. The three registers are at 3, 6 and 9 o’clock. Day and date at 12 o’clock.

The original dial has raised silver baton hour markers and a roulette-style (casino) telemeter scale. Oversized steel case of 46.5 mm x 42.5 mm excluding the crown, 16.5 mm thick, round pushers on the top of the case and a leather Rally strap.

This Difor chronograph houses a high-performing 7750 movement that has been in use for many years. The Bullead shape remains popular with watch collectors.

« A wild design and an indestructible Valjoux 7750: the best of both worlds for a vintage chronograph enthusiast. »
