Hey OF! I've decided to part with my 1977 Rolex 1500 black sigma dial as this isn't getting any wrist time. I tend to get most use out of watches 38mm - 42mm so this one is being listed exclusively on OF in the mean time. The Rolex Cal. 1570 movement is fresh out of service with my watchmaker and running as it should with no issues. Date function is also working as it should with no issues. ( I apologize for the lack of a movement shot, as have misplaced my Rolex case back opener) All parts of the watch are original to the watch. -Lugs and case appear thick with no signs of over polishing. -Case measures about 34mm (Not including crown) -Rolex bracelet is a 73850 fitted with original 557 end links. (**Please note that at some point a couple of links have been removed from the original bracelet**) A link or two may need to be added to the bracelet if you have a larger sized wrist. -Original signed Rolex crown. -"Black Sigma" Dial is all original and in my opinion the best part of this watch aesthetically. It has almost a dark gray / charcoal like appearance, with white gold stick markers. -Acrylic crystal is in great shape. -Serial is a 5 million serial dating to 1977 -Over all an honest example of a vintage Rolex 1500 Price: $2700 USD net to me OBO. Paypal is the preferred payment option and I will ship worldwide. I have references here on OF and plenty on eBay. Any questions at all please send me a private message or feel free to post in thread. Best regards, -Bernard
