By far the rarest reference of all Daytonas, the 6240 is a transitional model that introduced the screw down chronograph pushers case. While the later screw down pusher references 6263 and 6265 abound, the 6240 is a very rare watch.
Original case is stainless steel with dimensions of 37.5mm diameter by 12.5mm thick. Acrylic crystal. Aforementioned oversized screw down chronograph pushers and winding crown (all working great). The edge of the original bezel is as sharp and defined as the day this watch left the factory. While the original black bezel insert shows some light marking, the rest of the watch case is in phenomenally good condition, with its original sharp case lines, and appears to have been never polished or only extremely lightly polished. Easily mint+ condition.
Serial number 1298XXX dates production to 1965.
Original dial is black and in mint condition. Notably, this is a 'O T SWISS T O' dial (the text at the bottom of the dial under 6 o'clock). Original hands.
Original movement is the manual winding Rolex Caliber 722 with 17 jewels and adjusted to three positions. This caliber features column wheel construction - by far the superior chronograph caliber construction ever made. Movement is extremely clean.
Bracelet is Rolex folded Oyster reference 7835 with 271 endlinks. Bracelet has 11 links. Bracelet is in mint+ condition.
This is a great, all original and rare vintage Rolex Cosmograph Daytona in exemplary condition.
