Designer

Emmanuel Gueit

Emmanuel Gueit came from a family of Geneva jewellers and was barely into his twenties when he drew the oversized Royal Oak Offshore in 1993 — a watch the house's traditionalists resisted and collectors turned into an icon.

Historical significance

Rolex Datejust 126234-0017 Oystersteel White Gold Bright Blue Dial 36mm Unisex Watch sits within Rolex's Datejust line, introduced in 2017. It carries the house codes established since 1905 — stainless steel case, black lacquer dial dial and automatic manufacture calibre — and is one of the references collectors use to date the evolution of the collection.

Interesting facts

The case is finished by hand, alternating polished and satin-brushed surfaces in a single pass so the edges stay razor sharp.
The movement's bridges are decorated even where they will never be seen once the watch is cased.
Early production dials show a slightly different minute track, and collectors pay a premium for them.

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.
