I have a recent purchase of a 1940's Bulova 2 Register Chrono, Bulova case, Valjoux 23 movement. My issue/question is the dial. Everything I've seen points to a white dial color initially. This one has faded to a tan, with some additional fading around the numerals, perhaps due to the lume(?) The watch needs a servicing, and a cleaning would be par for the course. Should I refinish the dial? It's a decent fade, but uneven, and a fresh dial would make the piece pop a bit more. If I were to refresh the dial, any thought on where? It's not complicated, as far as dials go, but I would like it as close to period correct as possible. Thought?
