I have a fairly extensive vintage diver collection, and the ZRC is probably the most serious 'tool' in the group, not to mention cool looking.

 

The Gramds Fonds is my fave from them, esp the first issue ... there is a modern reussie too which is nice, just not as cool as the vintage pieces

 

Love these vintage ZRCs. Ive been hunting one for some time, and usually the ones up for sale are in poor condition.

 

There very cool watches indeed. Had a chance to see @watchistry’s collection when I was in San Francisco last fall. He’s selling a book of all the varieties on instagram.

 

One of the very few watches I sold, and definitely the one I miss :


Then I recently moved to the modern ZRC line which I love also :

 

All very cool divers. Sadly, no midize models as far as I can tell?
they’re famous for straps too

 

Cool factor, check!! Diver + day date compilations? Love

 

Really unusual design. Crown protection looks unique.
I guess those found for sale have mostly seen serious underwater time.
Never heard of these before. I'll be keeping an eye out.
