How to simply describe the Khaki Navy range? It's a watch where luxury meets water sports and is designed to be as at home in a seaside cottage or exploring the deep sea. A ceramic lunette with precisely engraved numerals adds style to the Hamilton Khaki Navy Scuba Auto H82315131 and protects it from corrosive elements like sand and salt water when at sea. The watch features a 40mm case, water resistance to 10 ATM (100m ) and an extra-readable dial. It's a high-performance watch ready for all your adventures on, in and under the water. Inside the case, the Hamilton H-10 Swiss mechanical movement (based on the ETA C07.611 built on the ETA 2824-2) ticks reliably with automatic winding. It operates at a frequency of 21,600 semi-frequencies per hour, has 25 jewels and, most importantly, an extended power reserve of 80 hours. The machine also has a"hacking" function (stopping the second hand when ordered) and the possibility of manual crown winding. The steel case of the watch is followed by a well-crafted steel bracelet with a folding clasp (the clasp has micro-adjustment). The practical black dial is protected by a sapphire crystal. The sapphire crystal is a great advantage in watches, as it is almost impossible to scratch. The anti-reflective layer guarantees great legibility even in the harsh sunlight. The blue seconds hand matches the blue details on the lunette. The hands and indices are coated with a luminescent layer, which guarantees longer luminosity and better legibility even in low light conditions. The case diameter of 40 mm makes the model a medium-sized men's watch. The water resistance of the watch is 100 m (10 ATM), so it is designed for all kinds of water fun except deep diving. Water resistance is supported by a screw-down crown.
