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 Planet Ocean 43 mm Ice Sapphire sits within Omega's Planet Ocean line, introduced in 1975. It carries the house codes established since 1848 — sapphire crystal case case, ice blue dial and in-house manual-winding — 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 bracelet tapers across its length, which is why the profile looks thinner on the wrist than the specification suggests.
- The reference was originally planned as a one-year run and stayed in the catalogue for well over a decade.

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.
