1960's Mondaine Valjoux 7734 vintage diver's chronograph
Modaine is best known for its modern Swiss Rail watches, styled after the clock design that is in use across the country's rail network. However, these are a relatively recent arrival, which were designed in the mid-1980s. Mondaine has a much longer history, with the brand appearing in the early 1950s.
This particular watch is a great example of the classic 1960's divers style of chronograph. The steel case, which measures a decent 38mm across, not including the crown, is in good original condition. There are some surface scratches, but no deep marks. The rotating bezel is in very good condition, and even retains its original lume pip at 12 o'clock. The case back does have some marks and there is evidence it has been worn with a NATO type strap in the past.
The dial is the real centre piece of the watch, with its beautifully aged tritium markers and hands, a neat feature being the lumed tips on the chrono second and minute hands. There dial, which sits under what appears to be the original crystal, is flawless.
Inside is a Valjoux 7734 movement, with date at 6. These reliable movements are a step up from the usual Landeron 48/248/51 types found in this sort of watch. It is in very clean condition and keeps time well, with good amplitude and low beat error. The chrono functions perfectly and resets exactly on its stops.
Overall, an awesome example of a classic tool chronograph. Supplied on a rubber tropic strap.
