The Bovet Mono-Rattrapante is a staple of the early Bovet watches, the purpose of which is to allow you to time two concurrent events.
This a very nice example of their legendary Mono-Rattrapante chronos from the 1940-1950s. The gloss gilt dial is in excellent condition. The iconic sword hands retain all of their original lume, and are also in great condition. The case is made of chronium, and like most of these cases from this era, shows signs of wear and has some scratches.
