TUDOR
Montres TUDOR SA is a Swiss manufacturer of luxury wristwatches based in Switzerland. The brand remains a sister company to Rolex SA, both companies being owned by the Hans Wilsdorf Foundation.
Over time Tudor became especially well known for its tool watches, producing watches for professional divers and the military. The first Tudor watches produced in the 1920s and 1930s bore a Tudor signature on the dial, with the horizontal bar of the T lengthened above the other characters.
