Historical significance
Tudor Ranger 42 mm Meteorite Platinum sits within Tudor's Ranger line, introduced in 1954. It carries the house codes established since 1926 — platinum 950 case, meteorite dial and high-beat automatic — and is one of the references collectors use to date the evolution of the collection.
Interesting facts
- The reference was originally planned as a one-year run and stayed in the catalogue for well over a decade.
- The movement's bridges are decorated even where they will never be seen once the watch is cased.

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.
