Hey all.

Always been on the look out for a GP 39 jewels after reading some stuff about it online.

Wondering if anyone can give me more information on the reference? I understand GP is able to give an extract too.

I like how it wears like a calatrava in terms of it's case style.

 

Here's a previous discussion of these with very good information.
