Tudor or Montres TUDOR SA (company name) is a Swiss manufacturer of wristwatches based in Geneva.

Tudor was founded by the same visionary that created Rolex – Hans Wilsdorf.

The name Tudor was registered under Wilsdorf as early as 1926; but their first watches, Art Deco-type in design, first hit the market in 1932. It wasn’t until 1946 that Wilsdorf created Montres Tudor S.A. with a clear vision: to offer the same quality of Rolex watches, at more modest prices.

Today, Tudor remains a sister company of Rolex, both companies being owned by the Hans Wilsdorf Foundation.
