The purest diamond expression of the Datejust 126300 dispenses with numerals entirely — every hour position is marked by a brilliant-cut stone, creating an unbroken ring of light around the dial. This replica of the 126300 diamond dial captures that full gem-set aesthetic on a 41mm Oystersteel platform, making the all-diamond look accessible without the six-figure entry point of the original.

The 126300 Up Close: Case, Dial and Bracelet
Without Arabic numerals or stick markers competing for attention, the full diamond dial lets the stones dominate. The 41mm case provides the surface area needed for this configuration — each stone is individually set and aligned to reflect light uniformly across the dial face. The diamond bezel adds a second ring of brilliance above. Explore the complete range in our Datejust collection.
The Oyster bracelet grounds the piece with tool-watch solidity — three-piece links in alternating brushed and polished surfaces, secured by a folding clasp that sits flat against the wrist.
