·As a fan and collector of vintage chronographs, no matter how prominent their brand name is, I was quite surprised that there seems to be no dedicated thread yet bringing together the unparalleled variety of watches powered by the foremost chrono workhorses of the most colourful and eclectic era in watchmaking, (the later 1960 and especially) the 1970s.
(At least I was not able to find such a thread easily – in case it was just my own fault please accept my excuses and delete/integrate my post into the respective correct thread. I was also not sure whether this should be part of the open discussion or other watch brands forum but opted for the open discussion in order not to exclude brands with their separate forum.)
To give this topic a little bit of historical context, here's the model history of this particular range of movements:

So, without further ado, let’s show here all kinds of models with the following movements, no matter whether these are well-known or rather obscure:
- Valjoux 7730: basic chronograph version (and nothing else but a renamed Venus 188)
- Valjoux 7731: like the 7730 but with a new balance cock
- Valjoux 7733: redesigned and further developed 7731
- Valjoux 7734: like the 7733 but with an additional date display (Poljots 3133 are also welcome)
- Valjoux 7736: like the 7733 but with an additional 12-hour counter
- Valjoux 7737: chronograph with a (10-minute) regatta countdown
I’m starting it off with a Sabina 7733 chronograph in a tonneau case on what is believed to be its original (signed) stainless steel bracelet.
