Watch from grandfather

I got this watch from my grandpa. It is one of the few watches that is still functional. Since this watch is much too good for daily wear I would want to trade this like for an everyday watch. What do you think?

Of course... and what the non working watches look like??

Welcome to the forum - we are a bunch of polite people here (I mean, most of us) so "Hi/Hello" 's and "Thank You's" help in a first post 😀

Having said that, comments in random order:
- Nice marine chrono 😀 with B/P 😲
- Shame on you for squandering your grandpa's legacy 🙁
- Good luck trading it for a Sub Date
- Plus what my friends said above

Hoping to read more from you and see more watches - that you will keep to honor your ancestor's memory...
