Historical significance
Tudor Royal 37 mm Salmon Grade sits within Tudor's Royal line, introduced in 1986. It carries the house codes established since 1926 — grade 5 titanium case, salmon dial and automatic chronograph — 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 reference was originally planned as a one-year run and stayed in the catalogue for well over a decade.
- The case is finished by hand, alternating polished and satin-brushed surfaces in a single pass so the edges stay razor sharp.

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.
