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.
- tass 2y agoAhould your original post read “chronometer” instead of chronograph? I also understand chronograph to mean a stopwatch complication, which is different from a chronometer certification.
- jordanb 2y agoDoh yeah. It's too late.
- DeathArrow 2y agoEven chronometer just means it passes chronometer specification, which for Swiss watches means that the movement is certified by COSC. 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.
