As far as I know there isn’t a specific model that people use to refer to it in listings. I just searched up Waltham, Waltham 25 jewels, etc and found this one. Searching Dexter Waltham as well but the people that know it’s from Dexter ask a lot for them

That’s such a beautiful watch!

It’s like 36-37

I almost bought one of these a while ago. I think I’ll have to revisit this one, amazing watch!

The UG is incredible!

This is awesome! Reminds me of some vintage Timex models.

Yeah it’s a cool one for sure
