OVERALL CONDITION: Very good vintage dating back to November 1971. I have intentionally left it unpolished because I know some of you prefer it this way :-). If I were you, I would leave it as it is since you can still appreciate all the sharp lines on it. Its internals are all in excellent condition. It has been keeping good time since I had it. However, since it is a vintage watch, I simply cannot guarantee accuracy - you may wish to get it regulated by your own watchmaker since environmental conditions do tend to play a part on the accuracy of these vintage movements. Guaranteed not to be Dead-On-Arrival though!
