Not quite original for parts.. 6309-7040 case, 6309-729a caseback, aftemarket bezel insert...Looks great Tony , and will await its finishing. It looks original
in many parts of being a Diver watch, but TST it will look great.
Like that Dial scheme, good thing and development in that one.
Yes I do remember them.. but may just leave without any markers as am adjusting to it..Weren't there some 6309 mods way back that had plain dials and the lume painted on the underside of the crystal? I wasn't a fan of them because it obstructed the view of the hands, but if done correctly, it could be ideal for your project because it'd leave the beautiful artwork on that dial untouched.
