Hello. I wonder if someone know anything about this old Chronograph movement called Valjoux 92 Astrolux?

Where it is from? Good quality? Valuation? Would be great to get some information, did not find so much searching on the internet.

It is running properly. With Kind regards

Valjoux made movement, not watches, so they sold movements to companies that assembled watches, these casing companies often re-badged movement with their own name.

What you have is a Valjoux 92 that was sold to "Astrolux" and used in one of their chronographs.

The Valjoux 92 (as well as the Valjoux 77) was different to many others of its time insofar that it has a "swivel pinion" (or tilting pinion) as a clutch. This was developed by Edouard Heuer in 1887 and is the clutch system that TAG Heuer have in their new Cal. 1887. It is also used in the most ubiquitous of chronograph movements, the Valjoux 7750, also in the Chronoswiss "Chronoscope". It is better suited to continuous running than the horizontal system (less wear) but the vertical system is best for that (less wear and less friction). Most older chronographs have the horizontal clutch, the modern ones tend to go for the vertical clutch system.

Did Edouard Heuer have a patent on the "swivel pinion" in Switzerland ? Anyway great that in the 1960's (and until now) (Tag) Heuer could still use the invention of its founder.

He may well have had - but obviously, it has expired. Otherwise, it would still be restricted to TAG Heuer watches.....
