Jewellery, watches and silver

The Omega Seamaster 300 is a diving watch introduced as part of Omega's professional dive range, built to withstand 300 metres of water pressure. It features a rotating bezel, luminous markers for underwater legibility, and an automatic movement, and became known through military issue versions used by British forces. It sits as a classic sports model within Omega's wider Seamaster family.

We recognise this model across the auction sites and keep every one we see together.

On a used one

Check the dial, hands and bezel insert for originality, as many examples have been reassembled from mixed parts or redialled over the decades. Military issue pieces should have correct case back engravings and matching serial numbers, and the movement should be verified against the stated reference.
