This is super. What made you choose JARF? I'm really excited for you to get your order because I know nothing about the factory but the DJs look sweet.
I just noticed the JARF 31mm has the same code engraved on the clasp as GMF/BPF so they're probably using GMF bracelets on the watch. They're very good bracelets.
My hope is that the case / dial is a step up from the GMF, since it's a little more expensive and they seem to have good experience with the DJ models. Keeping my fingers crossed for the color of the dial to be close.
