Rolex is the quintessential luxury watch and for that reason many stray away towards less dominant timepieces. Rolex has done some interesting things lately making it that much harder to disregard them. They got our attention after a collaboration with Fragment and now we’re checking them again thanks to a custom line from Alejandro Alcocer.

“Alejandro Alcocer, a watch fanatic and design entrepreneur who has previously delved into skateboarding, catering and handbag design, followed the legend of a black watch supposedly released by Rolex in the late 1960s for the Royal British Army soldiers stationed in South Africa. It was thought that only 500 were made, but Rolex never confirmed their distribution and they became the holy grail of watch collecting.”

So Alcocer made 50 of his own through a chemical application and they’re now available at Barneys.
