All kinds of wrong seen from a high tier rep perspective but that's one of the better shitters around. It doesn't have a date window so you don't have the issue with wrong magnification and all that.
That's Jason007's U1 factory. One of the OG AAA tier shops on DHGate and you can message him to get his whatsapp and get them cheaper if you buy off site since DHGate takes a cut. Also, bulk will get you a lower price as well. Maybe down to around $60 per watch or so. A little bit more if you go for the Miyota version, which you probably should as the 2813 can be iffy.
