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
HYT H20 44 mm Green Stainless sits within HYT's H20 line, introduced in 2012. It carries the house codes established since 2012 — stainless steel case, green sunburst dial and in-house tourbillon, manual-winding — 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.
- The case is finished by hand, alternating polished and satin-brushed surfaces in a single pass so the edges stay razor sharp.

Brand history
HYT has spent more than 14 years refining a single idea: a watch should outlive its owner. From the earliest workshop pieces to today's H0, the house has balanced technical ambition with a recognisable design language, and its collections remain among the most closely followed by collectors worldwide.
Vincent Perriard & Patrick Berdoz established HYT in 2012, working from Switzerland at a time when precision was measured by hand. The founder's obsession with finishing and accuracy still defines every HYT calibre produced today.
