In the 50s/60s/70s water resistance was often poor to non existent and as a result most watches had their dials degrade to some extent from exposure (depends by geographic area and conditions it was exposed to). Because of this it was common for the repainting of the dial to be part of a service, that can be done a number of ways but often involves removing dial furniture and applied Omega logo, stripping off the original paint, and repainting it before re-applying the dial furniture and luminous material. The trouble is the redial is never the same as the original, and varies from decent to poor to very poor. This one is very poor.
It is simply a dial that has been re-done. Not original finish. Just like the paint on old cars, the paint on the dials degrade. Some people feel the need to re-paint thus reducing the value of the watch to serious collectors.
