Hi OF, Up for sale today is my OP Date ref 1500 with the desirable grey sigma dial. This example is easily the nicest condition of any 40 year old watch I have owned and the presence of the inner and outer boxes doesn’t hurt either. Condition wise, the dial is flawless. The case is thick, unpolished with original bevels and brushing. Bracelet is super tight, and surprisingly, even the clasp is blemish free. If you’ve ever worn a watch with a bracelet, you know how quickly these pick up desk marks and so I’m guessing this one was bought, worn a handful of times and then locked up in a safe. Service history is unknown but it keeps time at +/- 10 seconds/day and date changes crisply around midnight. Highlights: - Mint condition - Flawless grey sigma dial - Correct date wheel with the open 6s and 9s - Comes with inner and outer box Additional Information: - Size: 34.8mm without crown, 19mm lug width - Serial & Year: 5xxxxxx; 1979 - Caliber: Automatic 1570 - Boxes/papers: Yes/No - Bracelet: Rolex oyster bracelet will fit wrist up to 8in wrist I’m asking $3750 USD which will also include insured shipping within CONUS. Other countries at cost. Paypal, Transferwise or bank wire only. Watch and I are in the US and I can ship worldwide (with some exceptions). Plenty of references available upon request. Thanks!
