The Navitimer 1 B01 Chronograph 43 TWA Edition has a transparent sapphire caseback featuring a TWA logo. Trans World Airlines, which was based in the United States, was a familiar sight at the world’s major airports throughout most of the twentieth century. This stainless-steel watch has a shimmering silver dial with contrasting anthracite subdials and is presented on stainless-steel mesh bracelet. Its in-house mechanical chronograph movement delivers both remarkable precision and a power reserve of approximately 70 hours. This model is also available with a vintage-inspired brown leather strap with either a pin buckle or a folding clasp.
