Ideal for use in the water, Hamilton's Khaki Navy Scuba Auto is available in the new 40 millimetre diameter size and in two new colours: military green with black details or navy blue with orange details. Both fittings employ a steel case, a Nato strap or alternatively a bracelet, also in steel, and a self-winding mechanical movement, calibre H10 (ETA base C07.111), with an 80-hour power reserve. They also have a unidirectional rotating bezel and a screw-down crown, which ensures water resistance to 10 atmospheres. Prices: from 645 euros (Nato) and 695 euros (bracelet).
