Stainless steel Rolex Oyster Perpetual Air-King-Date Precision model 5700 with silver / baton dial on Oyster 78350 bracelet. This somewhat collectible model with 738xxxx case number dates from around 1982, which is also consistent with its “G” clasp code. To change the date on this 1520-calibre model, one simply advances the main hands forwards or backwards past midnight. In fine condition for its age, but please note that (1) the dial shows some minor marks and other signs of age, (2) we no longer guarantee these older, plastic glass models to be water-resistant and (3) time-keeping may-not be as accurate as a modern, chronometer-rated Rolex. Offered with our own presentation box, warranty card and a certificate from the ALR Watch Register confirming that we checked it with them.
