The newest evolution of Omega's highly regarded SeaMaster series, the Aqua Terra delivers rugged handsome styling and superior performance, on land or at sea. This model places a large brushed steel case on a durable steel link bracelet. Featured beneath a virtually scratch-proof sapphire crystal, the round silver dial sports luminous hands and markers, a luminous sweep seconds hand and seconds indexes, and a date display at the three o'clock position. A see-through caseback allows a view of the self-winding Swiss automatic movement, which is enhanced by Omega's co-axial escapement, a technology that provides high precision and stable accuracy over long periods of use. This Omega watch is rated water resistant to a full 150 meters.  The Omega Men's Seamaster Aqua Terra Chronometer Steel Silver Watch is also known as 2503.30.00.
