I really only have 2 watches that I swap straps out on, my Speedy and my Hamilton.
The Hamilton NEVER sees the bracelet it came with anymore. Instead that one gets the most action with strap swaps. At least once a week, sometimes more. Just depends on how I'm feeling I guess.
The Speedy primarily stays on the bracelet. However I will swap a different strap onto it at least once a month, sometimes more. Just depends on how I'm feeling I guess...lol. Honestly though the Speedy gets worn to the office almost every day so if it comes off the bracelet it is because I want to swap it out to something more casual for the weekend. But again that is sort of what the Hammy is for...
Taking a bracelet off is definitely more time consuming (hardly, but still true), for me at least, so that is why the Hamilton gets more strap change action, just because it is easy and can be done in under 30 seconds usually. Sometimes even without a tool...
Specifically, for you, I'd imagine you'd do something similar to me and the Speedy. Keep it on the bracelet during the work week, and then switch it up to bee more casual (and probably comfortable) for the weekend.
