Wear it for a week and see how you feel. I wear a dress watch with t shirts and jeans all the time, but wouldn’t with workout pants. But we’re all going to have different lines.
If you want to tone down your watch’s formality, you could also put it on a suede or even a perlon strap (or stingray leather or a Hirsch premier leaf strap—lots of interesting options).
Probably one of the old Blancpain Leman Alarm GMTs. Track your home time, got an alarm. Good to go.
