First launched in 1952 and now one of the most recognisable watches around, the Navitimer began life as a tool watch with a slide rule that pilots used to perform various calculations, such as climb, fuel consumption or to convert miles/nautical miles/kilometres. The new Navitimer 1 Automatic 38 is a simplified version of the iconic Navitimer, minus the Chronograph. The bidirectional beaded bezel is inspired by the Montbrillant 1903. Women in particular will appreciate the 38mm case size. Also available in steel with a silver dial, 18k red gold bezel and brown alligator strap.
