Designer

Jörg Hysek

Jörg Hysek left Rolex and Seiko's European studios to build a design practice in Geneva, giving houses such as Vacheron Constantin, Breguet, Seiko and TAG Heuer their sculptural, architecture-led cases before founding his own brand, HD3.

Historical significance

Rolex Datejust 126234-0025 Oystersteel White Gold White Roman Dial 36mm Unisex Watch sits within Rolex's Datejust line, introduced in 2006. It carries the house codes established since 1905 — white gold case, white lacquer dial dial and automatic chronograph calibre — and is one of the references collectors use to date the evolution of the collection.

Interesting facts

The reference was originally planned as a one-year run and stayed in the catalogue for well over a decade.
The bracelet tapers across its length, which is why the profile looks thinner on the wrist than the specification suggests.

Brand history

Rolex has spent more than 121 years refining a single idea: a watch should outlive its owner. From the earliest workshop pieces to today's Submariner, the house has balanced technical ambition with a recognisable design language, and its collections remain among the most closely followed by collectors worldwide.

Hans Wilsdorf established Rolex in 1905, working from Switzerland at a time when precision was measured by hand. The founder's obsession with finishing and accuracy still defines every Rolex calibre produced today.
