I just have to point out that the Vallée de Joux (namesake of the Valjoux movement) is a beautiful spot in Switzerland that is located such that very few foreign tourists ever go there. Definitely worth the visit.
Earlier quoted context omitted.
A chronograph has a chronograph or detent escapement. The purpose of which is eliminate the sliding friction in the escapement and variability caused by viscosity change in lubrication with temperature. I never heard that a stopwatch makes a watch a chronometer. That sounds like a marketing gimmick.
Ahould your original post read “chronometer” instead of chronograph? I also understand chronograph to mean a stopwatch complication, which is different from a chronometer certification.

It does not imply a particular kind of escapement.
I have a Certina with ETA 2824-II and a Longines with ETA 2892-A2 which are inside COSC specs but not certified as chronometers.

Just avoid going there in winter, though... ( https://weatherspark.com/compare/y/53443~286/Comparison-of-t... )

A chronograph is any watch with a stopwatch complication. I'm really not sure what your concern with a lever escapement is, as this is used on almost all mechanical watches.

Dunno how it can be considered a "chronograph" when it has a lever escapement.

Regular (re-)submissions:
7750 and its clones like Sellita SW500 are some the workhorses of the watch industry. But kind of boring since they are omnipresent in chronographs. I'd prefer a chronograph with column wheel.
