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
Longines Conquest 44 mm Ice Quartz sits within Longines's Conquest line, introduced in 1998. It carries the house codes established since 1832 — quartz tpt case, ice blue dial and high-beat automatic — and is one of the references collectors use to date the evolution of the collection.
Interesting facts
- The bracelet tapers across its length, which is why the profile looks thinner on the wrist than the specification suggests.
- The movement's bridges are decorated even where they will never be seen once the watch is cased.

Brand history
Longines has spent more than 194 years refining a single idea: a watch should outlive its owner. From the earliest workshop pieces to today's Master Collection, the house has balanced technical ambition with a recognisable design language, and its collections remain among the most closely followed by collectors worldwide.
Auguste Agassiz established Longines in 1832, working from Switzerland at a time when precision was measured by hand. The founder's obsession with finishing and accuracy still defines every Longines calibre produced today.
