Revival of a steel Bovet Mono-Rattrapante Chronograph Watch (Second series) - part 1

The last time I embarked on a watch major restoration project was in June 2022 where a Rolex Prince was fully restored. For the end of 2024, I have decided to emark on a major restioration of a barn find old Bovet Mono-Rattrapante chronograph in its original untoched condition as follows. Owing to its conditions, the price is very resonable (at 1996 Antiquorum price).

It was in 1936 that Bovet created and patented a "mono-rattrapante" chronograph system that acted similarly to a split-seconds mechanism. The mechanism of the chronograph is started by the push button at 2 o'clock, while the push button at 4 would stop it and when released allowed the time to catch up to the actual time.  The Valjoux 84  was exclusively produced for Bovet Frères for their "Mono Rattrapante" between about 1936 and 1950.

As you can see from the photos, the case is full of rust, cracked crystal plus watch is not in working condition. It will be an interesting project restoring the watch. 

I have waited anxiously last night hoping that I can get this beauty and this morning when I woke up, I have finally have confirmation that it is mine. Once the watch has arrived, I shall start the restoration project with KK Sifu soon!
