Just picked this up today, so haven't had time to get it checked out by my watchmaker. I've owned a handful of these, and this is my first time encountering a blue dial. Nearly 100% this is NOT a refinished paint job, but would welcome others to chime in. Obviously a correct crown will need to be sourced, and it will need some TLC, but what do you guys think? I'm assuming its a cal. 560 or 565 with the toggle quick-set date. Anyone else own one of these?
