Designer
In-house design studio
The reference was drawn by the manufacture's internal design office, where case, dial and movement architects work alongside the watchmakers rather than as an outside commission.
Historical significance
HYT H1 36 mm Skeletonised Grade sits within HYT's H1 line, introduced in 2015. It carries the house codes established since 2012 — grade 5 titanium case, skeletonised dial and in-house automatic with 22k gold rotor — 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 case is finished by hand, alternating polished and satin-brushed surfaces in a single pass so the edges stay razor sharp.
- Early production dials show a slightly different minute track, and collectors pay a premium for them.

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.
