Omega Seamaster Diver 300M 44mm 210.30.44.51.03.001 Super Clone Watch

The Omega Seamaster Diver 300M Chronograph 210.30.44.51.03.001 is for buyers who want the larger Seamaster presence and an elapsed-time display, not simply another three-hand diver. Its 44mm 316L stainless steel case measures a stated 16.8mm thick and 52.8mm lug to lug, with a listed 226g weight on the bracelet. Those proportions are part of the choice: the watch wears with deliberate mass and is better suited to someone who wants the case to remain visually present.

The blue ceramic dial uses laser-engraved wave detailing, while a matching blue polished ceramic bezel carries a white enamel dive scale. Sapphire crystal with double anti-reflective coating keeps the layered dial and bezel open to view. A date display adds calendar utility without taking the place of the chronograph layout.

The important functional detail is the single 3 o’clock chronograph register combining the 12-hour and 60-minute counters. The Super Clone Calibre 9900 combines the 12-hour and 60-minute chronograph counters in that single register, so elapsed time is read in a clock-style arrangement rather than across separate subdials. It is the feature that separates this reference from a standard diver and gives the broad dial its purpose.

The movement is specified with approximately 36 hours of power reserve. For a buyer comparing chronograph versions, the movement layout and the correct 44mm case are more useful decision points than generic claims about performance.
