The firm of Harry Winston has the greatest respect for noble materials. Fashioned in platinum and produced in a limited, individually numbered series, this diver’s watch features a Girard-Perregaux 3 100 calibre automatic movement. The case, which is water-resistant to 100 m and has a screw-down back and crown, features a notched, satin-finished unidirectional bezel. The steel-blue hands and hour markers are tritium-coated to facilitate reading the time. This exceptional timepiece is available on a leather strap or a platinum bracelet (approx. 105 grammes), with a white gold folding clasp.
