The purpose of this page is twofold. One – to provide easy access to general information on this iconic Omega dive watch. Two – to help potential buyers locate pre-owned & new models online. The Omega Seamaster 300 is one of several professional divers’ watches featured in the Omega Seamaster dive watch range
Don’t confuse this Omega Seamaster 300 with the Omega Seamaster Professional Diver 300m or the Seamaster Planet Ocean. A quick glance at any of these models should be time enough to determine which model it is. If BOTH hands have arrowhead pointers – it’s an Omega Planet Ocean. If ONLY the hour hand has the arrowhead it’s the Seamaster 300 – featured here. The Seamaster Diver 300m is totally different with distinctive skeletal (hollow) hands.

Glowing with Super-Luminova
Large triangular numeral markers and hands all encased in super bright Super-Luminova. The all important minute hand glows a different colour to all other hands and markings to help differentiate during essential dive timing in low light conditions
Master Coaxial Movement
There’s no doubt the Seamaster impresses from the exterior – but it’s inside that the really beauty can be found. Powered by Omega’s Master Coaxial Calibres 8400, 8402 and 8800 movements (model dependent) – the Seamaster excels in mechanical chronometer accuracy.
The Omega Calibre 8400 – a Self-winding movement with Co-Axial escapement. It’s resistant to magnetic fields greater than 15,000 gauss. Featuring a free sprung-balance with silicon balance spring, two barrels mounted in series, automatic winding in both directions. The bridges and oscillating weight are both decorated with an exclusive Geneva wave design in arabesque
The Omega Calibre 8401 – a Self-winding movement with Co-Axial escapement. Featuring free sprung-balance, 2 barrels mounted in series, automatic winding in both directions. The 8401 stands out with it’s oscillating mass and balance bridge in red gold. Luxury finish with an exclusive Geneva wave design in arabesque
Once fully wound from it’s automatic motion wound movement – the Seamaster will run for 60 hours. If the watch has been off the wrist for some time it can be boosted by manual winding without the need to pull out the crown (sometimes referred to as hacking)
Confused between models?
If you are finding it hard to distinguish between the dif[ferent Omega models – in particular the Omega Seamaster 300, the Omega Seamaster Diver 300m and the Omega Planet Ocean hopefully this will help.
Omega Seamaster 300 hands
If it’s an Omega Seamaster 300 you are interested in – please check the hands look like these above. Just the hour hand with the arrowhead – the minute hand has no arrowhead. We see about 50 – 75% of eBay listings wrongly referring to the Diver 300m as a Seamaster 300. They are both great watches – but please ensure you are getting what you want.
Omega Seamaster Diver 300m hands
The Omega Seamaster Diver 300m is far more common than the Seamaster 300. It’s clearly distinguishable from the others with it’s hollow hands. One with triangular luminous tip (minute hand) and the hour hand with a round luminous marker
Omega Planet Ocean hands
These are the hands of an Omega Planet Ocean. Both hands are solid and both terminate in a luminous arrowhead.
Note > Omega do have some exceptions to these general rules such as limited edition models and such like. This is a just an “at a glance” guide.
