Subtle aesthetic changes – major innovations in technology – the Omega Seamaster 300

Omega Planet Ocean – our favourite

In our view – perfection – the Planet Ocean 600M with Co‑Axial Master Chronometer 43.5 mm

At ChronoDivers.com we do have a favourite – and that’s the Planet Ocean. Whether it’s the aesthetic beauty, the distinctive arrowhead hands or the mechanical wizardry of the Omega Master Chronometer calibre 8900 visible through the transparent caseback. We don’t know – probably a culmination of everything that make the Seamaster Planet Ocean one of the most desirable dive watches on the market.

Omega Ploprof – 1970 to today

If extreme depth is an essential requirement then the watch that goes deeper than most is the Omega Ploprof. The Ploprof is a term adopted by Omega for their 1200m water resistant profesional divers watch. The watch’s name says it all – Ploprof – is an abbreviation of the French for professional diver – plongeur professionnel.

The Omega Ploprof 2016 model with titanium case and automatic helium escape valve

When first introduced in 1970 it was rated to 600m. The new version – released in 2016 – is rated to 1200m. Featuring a titanium with ceramic bezels (some models) and the OMEGA Co-Axial and Master Chronometer calibres. The new Omega Ploprof assures it’s lucky owner of the highest levels of accuracy and reliability.

Expect to pay….

Expect to pay somewhere in the region of US$5,000 to US$10,000 for a standard Omega Ploprof (steel case, black rubberised dive strap or Omega “shark” bracelet, black face and bezel with orange helium release valve). The difference in price takes in to consideration condition, provenance, age, service intervals (if any) and whether it comes with box, papers etc. As with all these luxury watches – there is always a remote chance it may be a fake. Please take all necessary steps to help avoid buying a fake watch

Recognising Different models

A glance at any of the current models should be time enough to determine which stable it belongs to. If BOTH hands have arrowhead pointers – it’s an Omega Planet Ocean. If just the hour hand has the arrowhead it’s the Seamaster 300. If both hands are hollow, with a triangular luminous marker on the minute hand and round luminous marker on the hour hand, it’s a Seamaster Diver 300m. If it’s an Omega Ploprof … it’s obvious with it’s distinctive helium release valve. More detail below ….

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 iyou are looking to buy 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.

Omega Dive Watch History

Omega launched their first official dive watch in 1948 – the Omega Seamaster – a name now synonymous with quality and underwater reliability. The first models utilised their many years producing military grade watches with high levels of water resistancy – not normally found on other watches of that time.

Fast forward 9 years to 1957 and we have their first 300m version. The Seamaster had most definitely arrived and quickly established itself as the must have watch for professional divers. In 1963 Jacques Cousteau – a renowned oceanographer & diver – wore the Seamaster 300m. His entire team wore the watch throughout their Conshelf II experiments in the Red Sea – a very impressive endorsement indeed.
