Designer

Gérald Genta

Gérald Genta (1931–2011) trained as a goldsmith in Geneva and became the most influential watch designer of the 20th century. Working freelance, he sketched the Audemars Piguet Royal Oak overnight in 1970, followed by the Patek Philippe Nautilus, the IWC Ingenieur SL and the Bulgari Bulgari — defining the integrated-bracelet luxury sports watch as a category.

Historical significance

Rolex Datejust m126300-0002 Oyster Perpetual 41mm Blue Index Dial Mens Watch sits within Rolex's Datejust line, introduced in 2009. It carries the house codes established since 1905 — stainless steel case, black lacquer dial dial and manual-winding manufacture calibre — and is one of the references collectors use to date the evolution of the collection.

Interesting facts

The movement's bridges are decorated even where they will never be seen once the watch is cased.
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.
