Thoughts of this 1960s Zenith Subsea Diver AH3637 Orange

[Nerves69]

Came across this “Big Orange” example of the AH3637 Zenith divers. I don’t know much about them beyond the “ Big Lemon” version and they are not easily found. Love the orange . Reminds me of the Zenith Revival of the A3648. Where does this model come in compared to that model?
Any insight is appreciated!

I've not set my mind to it yet but I'd like to find one at some point. I'm wearing the Defy diver from the same era almost daily and am just enamored with her.

I prefer the design of the original A3648 as it's less bulky and more interesting to look at. It also fits in better with the rest of the Defy range which gives it something of a family identity.

This A3637 looks a little unbalanced on the strap to me, I think it would look better on a bracelet.
