Bovet, “Mono-Rattrapante”, patented “single” split-seconds with one hand

It was in 1935 that Bovet Frères & Co. created and patented a “mono-rattrapante” chronograph system that acted similarly to a split-seconds mechanism. This chronograph movement with a single hand is elaborated by Bovet on the Valjoux 14’’’ calibre 84.

This particular wristwatch features the three normal functions of any single-button chronograph, activated through the push-piece at 2, enabling the chronograph hand to: “start” / “stop” / “return to zero”.

In addition, there are two further functions activated through the push-piece at 4:
1) By depressing the push-piece, the single chronograph hand stops.
2) By releasing the push-piece, within a maximum time of 60 seconds, the hand jumps forward, catching-up the seconds elapsed in the meantime.

Two versions of this wristwatch exist:
· The first, features a round, flat push-piece at 2 and an olive-shaped push-piece at 4.
· The second version has either a square or a round water-resistant push-piece at 2 and at 4.
