The Omega Seamaster 300m diver is a legendary watch! This timepiece offers 300m water resistance, older models had an aluminum bezel (ref. 2531.80) whereas new versions have a ceramic one (ref. 212.30.41.20.03.001). The Omega Seamaster Professional 300m diver was first featured in the famous James Bond movie “GoldenEye”, worn by Pierce Brosnan. Interestingly, the model used in this movie was quartz powered (ref. 2541.80) which had a 1438 movement before 1994 and a 1538 movement later on. The 2531.80 has the same look and feel, but houses an automatic ETA 1120 movement.
