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
Tudor 1926 37 mm Silvered 18k sits within Tudor's 1926 line, introduced in 2020. It carries the house codes established since 1926 — 18k yellow gold case, silvered opaline dial and automatic, swiss lever escapement — 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.

Brand history
Tudor has spent more than 100 years refining a single idea: a watch should outlive its owner. From the earliest workshop pieces to today's Black Bay, the house has balanced technical ambition with a recognisable design language, and its collections remain among the most closely followed by collectors worldwide.
Hans Wilsdorf established Tudor in 1926, working from Switzerland at a time when precision was measured by hand. The founder's obsession with finishing and accuracy still defines every Tudor calibre produced today.
