Introduced in the 1940s, the Bovet Mono-Rattrapante is a two-register chronograph powered by the Valjoux 84. It has a similar function as a Rattrapante, but with one hand, hence ‘Mono’ Rattrapante.
The chronograph is a mono-pusher, activated by the top pusher. The bottom pusher, when pressed, stops the chronograph hands for easy reading. When this pusher is released, the hands go back to where they should be, if not stopped.
This example is the most coveted version (black dial with lumed numerals) and is in mint condition. The dial is turning brown on some areas, have started a tropicalization process, which will make it even more desirable.
Overall condition is mint. Dial is in superb condition, with some patina to the indexes. Case is in excellent shape, obviously unpolished. Pushers look perfect. Glass is in perfect condition. The movement was fully serviced.
