Omega Seamaster 120

Jewellery, watches and silver

The Omega Seamaster 120 is a diver's wristwatch from Omega's Seamaster family, water resistant to 120 metres (400 feet). It was offered in steel cases with both quartz and mechanical movements, aimed at a sporty, everyday diving and leisure use rather than professional saturation diving. It sits below the deeper rated Seamaster models such as the Ploprof or 300 in the range, serving as an accessible entry level dive watch.

1970s to 1980s

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

On a used one

Check the condition of the dial lume and bezel insert for fading or damage, confirm the movement matches the case and that service history and papers are present, and inspect the case back and crown for correct water resistance seals.
