The Diver Professional 300m is most famous for its "train-track" five link steel bracelet, its helium release valve at the 10:00 position, the wave pattern dial on certain model generations, and the skeletonized handset.

In 2019, three specially made experimental watches dubbed Omega Seamaster Planet Ocean Ultra Deep Professionals survived a 10,928 meter dive to the bottom of the Mariana Trench affixed to the bathyscaphe Limiting Factor, setting a new world record at the time as deepest dive watch by 12 meters.

The Omega Seamaster first made a diving record in 1955, when diver Gordon McLean reached a depth of 62.5 metres (205 ft) in Australia.

In the proceeding films starring Pierce Brosnan as the titular character, James Bond wore an Omega Seamaster Professional Diver 300M Chronometer 2531.80.00.

She recognized the history of the Omega Seamaster watch in the British military (notably the Special Boat Service, synonymous with the character of Bond) which furthered her decision.

[13] The term Co-Axial represents a specialized watch escapement exclusive to Omega that was developed in 1970 by British horologist and watchmaker George Daniels.

The escapement provides the release of energy from the mainspring to the going train that further controls the function of the moving parts that measure time and other complications.

The Swiss lever, although the mainstay in the industry, has the capability to be strong on energy conservation but needs considerable lubrication between the impulse pallet and the escape wheel teeth due to sliding friction.

1120 (finished chronometer grade ETA 2892-A with two extra jewels) A, B, and C are similar two-tier co-axial movements, but C is the first version to solve certain problems prevalent in A and B.

According to studies by the COSC, the majority of watches in for service from 4+ years are primarily suffering accuracy issues due to magnetized movements.
