The OceanX Hawkmaster HMS112 is a high quality watch. It pays tribute to watches of the present and the past, but does have key OceanX elements. Under the hood you will find an tremendous automatic, Miyota 9015 movement. The glass is of course sapphire glass with an anti-reflective coating and a cyclops lens over the date. The watch is water resistant up to 100m, enough for most adventures! The Hawkmaster is a beautiful piece that is both versatile and rugged.
