The 2015 D15 is a GMT traveller's watch that deviates from the refined dress watches of the Altitude collection. The case, available in grade-5 titanium or grey gold, has a rugged yet elegant design. It reminds us of iconic models like the Bulgari Octo, Patek Philippe Nautilus, and Audemars Piguet Royal Oak with its sculpted feel and artful lines and finishes. Reference 102-GHLZ boasts a white gold case and a sleek silver dial with black gold hands and accents. Perfect for the fashion-forward globetrotter.
