Stainless steel Oyster Perpetual / Officially Certified Chronometer model 6569 with silver / baton dial and rivet Oyster bracelet. This watch appears to be 50 years old, a conclusion supported by its case number, the 1 57 stamp inside the case back, the 61 mark on the bracelet clasp and what appears to be its original purchase receipt dated January 1962. The watch is running well, but because of its age we are selling it with only a ONE year warranty and cannot guarantee modern levels of accuracy. Expect perhaps +/- 10 seconds per day. As a vintage piece it is a bargain, and should be bought as such rather than as a perfect time-keeper.
