I recently acquired a vintage WWI Leonidas with shrapnel guard and would like to have it restored. The case, dial, etc. shouldn't need too much work, but the movement isn't running and I have not opened the case to check it because I am concerned about the radium paint on the dial and hands. Since I have not seen the movement, I am a bit worried about being overcharged for repairs that are not needed, about original parts being swapped for lower-grade substitutes, etc. Could anyone suggest a reputable, honest, and competent vintage watch restorer?
