Replacing the dial on a Seiko 6309 watch
I bought a Seiko 6309 watch (built in the 1980's) on Ebay, however it had a crappy aftermarket dial (hands and bezel insert are also aftermarket). The problem was that the luminescent material is green on the dial and the original has white lume - but really it just looked bad. The pics make it hard to see how green the lume was, but in any case, another aftermarket dial which appears closer to original was pretty cheap so it was worth the time. I do have some specialized tools from Ebay (most of which were pretty cheap) - though it could probably be done without them if you have the nerve. The tools I would consider essential would be the watch hand puller, some Rodico Green Putty (great for cleaning as well), a watch case opener and a small screwdriver. You may be able to get away with setting the hands with a ballpoint pen (with the ink cartridge removed) or maybe some other tools. A magnifier is also handy if you don't have great near vision. Below are some pics I took of the process, I will try and add captions here and there, but they were really for my future reference in case I want to swap the dial or hands later.
