Rolex Bamford Daytona Ref. 116520

This is a Bamford Rolex Daytona, reference 116520, a genuine steel Daytona customised by Bamford Watch Department, the London house known for its blacked-out and reworked luxury watches. To be clear on what that means: the base watch is an authentic Rolex Daytona, and Bamford has modified it after it left Rolex, typically with a coated case and a custom dial and bezel treatment, so it is real Rolex at its core but a customised piece rather than a factory one.

Underneath the Bamford work it is the 116520 generation of the Daytona, which matters because this is the reference that introduced Rolex's own in-house movement. It runs the automatic Caliber 4130, a self-winding chronograph with a column wheel and vertical clutch and around 72 hours of power reserve, driving the three sub-dials, with the tachymeter scale on the bezel for reading speed. The 40mm Oyster case keeps the Daytona's serious build and screw-down pushers.

Bamford Daytonas are made in small numbers and have their own strong following, which is much of the appeal, this is a recognised name in customisation rather than an anonymous mod. That said, because the work is aftermarket, the watch sits outside Rolex's warranty and service programme. At Konesseur, every watch is authenticated and inspected in Dubai before listing.
