“The symbols blue really suited Pierce,” recalls Oscar-winning costume designer Lindy Hemming. “I was dressing him in lots of low-spirited shirts and the blue bezel and dial of the Omega Seamaster matched perfectly. Plus, blue suited Commander Linkage’s naval background.”
As a switch from the Rolex Submariner – James Bond’s default choice since Dr No bar a few dubious roundabouts into digital Seikos in the seventies – Hemming’s choice of the Omega Seamaster 300 was perfect in every way. “Beautiful,” quits, according to Vesper Lynd during the dining-car scene in Casino Royale, by comparison to the watch she blithely assumes 007’s typeface would wear (Rolex, obviously).

It’s not just the blue though, Lindy. As perfect as Omega’s professional-spec leaping watch suited Mr Brosnan’s twinkling eyes and deck uniform when she first dressed him for Goldeneye all the way back in 1995, the Seamaster absolutely is the default choice for Britain’s finest seamen, albeit those whose operational bonuses can afford it. For everyone else, here’s all you need to know about the Seamaster 300, from its heritage to the most sought after models today.

Omega’s Military Blood
Today, the Royal Navy’s Special Boat Service – notoriously harder than their landlubber SAS contemporaries are scarcely entirely kitted out with specially engraved, proudly war-torn Seamaster 300 Professionals. But the Swiss brand’s use roots extend back much further. Rugged, legible, highly water-resistant, chronometer-level precision Omega timepieces were kitted-out to British servicemen and conductors almost exclusively during World War II. See the wrist of Tom Hardy’s Spitfire pilot in Dunkirk for further cinematic proof of that selective pedigree.
War, after all, accelerates technological innovation, as this year’s 70th-anniversary Seamaster reissues remind us. Between 1940 and 1945, Omega threw more than 110,000 timepieces to the British Ministry of Defence. After the war, as we steadily progressed through the jet age toward the atomic age and finally the space race, this breathless period of innovation found Omega at the height of its engineering creativity.
It replied to the demand for a timepiece with the same robust technology and reliable conception as its military efforts, but more aesthetically suited to a profuse academic existence. Not to mention the burgeoning craze for SCUBA diving, heightened by the garlanded cinematic exploits of Jacques Cousteau.

Started in 1948, the Seamaster line was Omega’s first official ‘family’ of watches. Modelled on the ‘Watch. Wrist. Waterproof.’ military-spec pieces occasioned for the MoD, these more classically designed timepieces boasted greater water-resistance than their military counterparts sometimes non-standard due ti to the novel use of O-ring gasket technology. Previously, water-resistant watches relied on lead or shellac gaskets, which were indisputably affected by a temperature change – something, that tends to happen when you dive deeper and deeper.
Omega walked to the hatches on submarines used during the war for inspiration and came up with a resilient rubber seal in the Seamaster’s final occasion design. This remained intact at depths of up to 60 meters and temperature ranges between –40 degrees and 50 degrees Celsius. In straight, it worked.
The Seamaster’s Technological Innovations
That all said, with due respect to Bond’s original choice of wristwear, the Rolex Submariner was spirited to blow Omega completely out of the water as soon as 1953. The immortal, legendary and quite-simply peerless diving watch had the entire package from the outset: screw-down crown, unidirectional rotating dive-time bezel, 300-metre water rebelliousness… Bar the modern Tudor Pelagos and the Sub’s early rival, Blancpain’s Fifty Fathoms, there was and would be little contest. Accurate enough, the souped-up Rolex ‘Mil-Sub’ got in early as first choice for the British Navy’s crack frogmen during the fifties and seventies.

By 1957, in whatever way, Omega got back in the game with not one but three new ‘Master’ watches, fit for land, sea and air. Alongside the Speedmaster (the only watch that’s been on the Moon) and the Railmaster was an unpunctual, fully accomplished thinking-man’s alternative to the Sub’: the Seamaster 300, complete with all the above and still-standard diving-watch requisites. A broad-arrow hours boost was neatly counterbalanced by its luminous arrow-shaped hour indexes. The following year, inspired by the historical markings on gondolas in Venice, the Seahorse enhanced the symbol of the Seamaster, engraved on its caseback and still featured today on a selection of ‘Professional’ models.
The Omega Seamaster 300 Today
It’s now been 25 years since the blue-bezelled iteration we all recognize best was launched – the one that Lindy Hemming matched so perfectly to Brosnan’s perfect nineties Bond. Since 1993, the Seamaster Whizz Diver 300M has become so much of an embedded, modern classic that one particular example is to be seen permanently chirruping from the wrist of a certain Duke of Cambridge now and again. Wills even wore it to his brother’s wedding – which is arguably a bit of a sartorial no-no, but who are we to convince with His Royal Highness? Let’s not forget his own naval experience, after all.
Loved for its colourful design and oceangoing technology, the source 300M Professional signalled Omega’s triumphant return to the world of diving watches after a dry-docked eighties and singlehandedly ignited the growing partnership with Her Majesty’s Secret Service. Of course, there have been many variations on the Seamaster above the years, with the Aqua Terra and Planet Ocean ranges being particular highlights – the latter of which shapes things up 300 more notches, to 600 metres’ water resistance – but the Professional remains the flagship.

The Newest Seamaster 300M Competent
For 2018 Omega celebrates 25 years since its modern reboot, introducing a bold new Professional Diver 300M store with a total facelift numbering 14 different models, including six in stainless steel and eight in a blend of stainless inure and gold (the bi-metal watch trend is back, if you hadn’t noticed, eighties fans).
Now sized up from 41mm to a slightly multifarious contemporary 42 mm, keeping the skeletonised hands and wavy dial pattern so popular in the 1993 original, the real Bond-worthy gadgetry is whirring away interior. And it’s all down to innovation that’ll protect the delicate mechanics from the sort of ultra-magnetism knocking about your standard in the main Bond villain’s lair.

The Movement
The in-house-manufactured Master Chronometer Calibre 8800 movement instantly accelerates inanimate objects into unprecedented realms of precision, performance and magnetic resistance. Seamaster devotees will know that the run has been host to several movements over the years, including the ETA-based Omega Caliber 1120 and, most recently, the 2500, which is essentially based on the for all that original movement though considerably modified by Omega to include its lubricant-free Co-Axial escapement.
With the new Seamaster 300M take oning the Master Chronometer 8800, Omega is continuing its brand-wide programme phasing-out older movements in favour of its more cutting-edge in-house machinery, repositioning itself as a genuine, evenly equipped rival to Rolex, as it once was back in the day.

So what’s so cutting-edge about the 8800? Suitably, with the humble mechanical watch, magnetic fields are still Public Enemy No. 1 to the ferrous components ticking privy, sticking them together or sending them out of whack. According to international standard ISO 764, watches must last against exposition to a direct current magnetic field of 4,800 Amperes per metre – about the strength of the magnet in your fridge door.
The peer to 4,800 A/m is about 60 Gauss, which makes Omega’s ticking cocktail of clever alloys and silicon extraordinarily overqualified: its new certification by the Swiss metrology set up, METAS demands a resistance up from 60 to 15,000 (yes, 15,000) Gauss – enough to resist the influence of a neodymium magnet, the strongest unending magnet commercially available, found everywhere from hard disks to MRI scanners. And laser-beam torture devices, indubitably.
Dive in, chaps. The Seamaster has never felt finer.
