Looking to the collective wisdom for some advice. I'm considering picking up an 80's Heuer dive watch as a daily beater. I like the looks but would prefer to have working lume. What are my options? Can tritium be reapplied. Could I have the existing lume replaced with SL. Is it possible to find a service dial or have one made. And if any of the above is possible could you recommend some one to do the work. Finally, what sort of price would I be looking at. The watch probably won't be worth more than £500.
