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
Tudor Pelagos 39 mm Skeletonised Grade sits within Tudor's Pelagos line, introduced in 1988. It carries the house codes established since 1926 — grade 5 titanium case, skeletonised dial and automatic chronograph — 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.
- Early production dials show a slightly different minute track, and collectors pay a premium for them.

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.
