Old movie and if I remember right it was on a channel called TNT back in late 90s and was about 10 yrs old

The movie was about a guy who kept track of all the happy moments in his life by using a pocket watch.

He’d start the timer on the watch when he was happy and stop it after.. If that’s what was actually happening .. It might have been a foreign movie .. Not sure

I know the details are sparse but I’ve posted this on multiple places and no one found what the movie was.. I’ll keep my expectations low 🙂
