Does anyone else also collect Stop Watches?

Just curious how many others out there have dipped their "toes" into Stop Watch collecting?

I have picked up a few vintage references that piqued my fancy, and obtained some with the Baltic x Peter Auto collaboration, but still on the edges of collecting.

I know there are more out there since I have lost several auctions for vintage Heuer stop watches and a few others.

Here are a few in my collection:

Excelsior Park (1960s) running the Valjoux 7770


Two different Elvia Bullhead (1970s) running the Valjoux 7770


Baltic x Peter Auto



I have been tempted, but... I just know that it would sit in a drawer. That Elvia is something.
