Watch specifications

Special characteristic

Chrono Bronze classic, caseback

Our display back case uses a blue anti-reflective sapphire crystal and thus allow for an unobstructed view of the pulsating calibre. One has the feeling that the soul of the mechanical automatic movement can both be felt and seen. The watch is alive. Together with the possibility of the custom labelled rotor, each watch becomes a truly personal gift – even to oneself.

Special characteristic

classic simple bronze pushers

Non-screw pushers or just simple pushers as we call them are smooth and make for a sleeker appearance. The stop function is activated simply by pressing down on the pusher.

Special characteristic

ETA 7750 Movement

After the takeover by ETA, the Valjoux 7750 was re-named the calibre ETA 7750. This is quite possibly the most successful automatic chronograph movement of all time. The calibre stands out due to its high degree of accuracy and robustness. It has 25 stones, a ball bearing mounted rotor and a uni-directional winding mechanism. The 7750 has a 1/8-second counter, a 30-minute counter, a 12-hour counter, 28,800 half oscillations per minute and has a power reserve of ca. 44 hours. The loss of accuracy is 1-6 seconds per day. Movement revisions are recommended every 3 to 8 years

Special characteristic

Bronze

We use a very individual bronze alloy sourced in Zurich. Bronze is anti-magnetic, resistant to wear, is elastic, slightly more brittle and 10% heavier than stainless steel. Above all, it stands out due to its resistance to seawater. Beneath a layer of oxidised copper, the material offers lasting protection. The discolouration of the bronze is particularly appealing and means that every watch, over time, evolves into a unique piece—one solely influenced by the life of the watch owner. While bronze can stain, these stains are usually removed in the normal laundry process.
