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
Omega Seamaster 41 mm Blue 18k sits within Omega's Seamaster line, introduced in 2006. It carries the house codes established since 1848 — 18k rose gold case, blue "grande tapisserie" dial and in-house automatic chronograph — 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.

Brand history
Omega has spent more than 178 years refining a single idea: a watch should outlive its owner. From the earliest workshop pieces to today's Speedmaster, the house has balanced technical ambition with a recognisable design language, and its collections remain among the most closely followed by collectors worldwide.
Louis Brandt established Omega in 1848, working from Switzerland at a time when precision was measured by hand. The founder's obsession with finishing and accuracy still defines every Omega calibre produced today.
