In 1969, man visited the Moon for the first time, the U.S. Navy’s pioneering SEALAB program ended and On Her Majesty’s Secret Service saw James Bond in action in Switzerland’s majestic Bernese Alps. It was also the year of manufacture for this highly collectable Omega Seamaster 300 ‘Big Triangle’ 166.024 diver’s watch.
Often called ‘the James Bond watch’, Omega’s Seamaster, with its unmistakable Jean-Pierre Borle-designed seahorse logo, holds a prominent place in the luxury divers’ watch pantheon.
One of the world's most iconic dive watches
The Omega Seamaster 300 debuted alongside the Omega Speedmaster and Railmaster in 1957. However, it wasn't until 1963/64 that the reference 165.024/166.024 (date version) would come to be. Even though only produced for six years, the references 165.024/166.024 would see numerous iterations which makes exploring this historic watch all the more interesting. For those looking to learn more about these wonderful watches, we strongly recommend heading to the highly informative Omega Seamaster 300 website. On a personal note we'd also like to send a huge thanks to its author who was incredibly generous with their time in answering some of our questions.
Military history: the Omega Seamaster 300 ‘Big Triangle’ 166.024
During the Cold War, various militaries used Omega’s Seamaster, including Britain’s Ministry of Defence (MoD). Whilst this example lacks the military markings to the case back, the Omega Extract does show it was delivered to the NAAFI (Navy, Army and Air Force Institutes) on October 7, 1969. The thinking is the watch was likely a private purchase on discount through the NAAFI explaining the lack of military markings.
That ‘big triangle’ means unquestionable collectabilityFrom sword hands, iconic dial design and ‘Certified High pressure’ engraving on the case back, the Omega Seamaster 300 ‘Big Triangle’ 166.024 is instantly recognisable to collectors worldwide. Of interest, Omega seemingly added the ‘big triangle’ (for better legibility and watch orientation) plus the lumed sword hands in 1966–67 after consulting with military users. The result is a striking signature feature; it assertively dominates the black dial, with its luminous hour markers, ‘T SWISS MADE T’ marking and Arabic numerals at ‘3’, ‘6’ and ‘9’.

Do watches come with original box and papers?
It depends on the individual watch. You can see details under "The Basics" heading on this page. For the majority of vintage watches their original box and papers have been lost to time. Whilst they are nice to have, it’s important to note that “box and papers” DO NOT authenticate a watch despite what many in our trade say. It’s also important to realise alot of sellers (including some of the most well known in the UK) put together full sets of box, papers, hang tags etc by buying blank paperwork and boxes in the secondary market. This is a very regrettable, but unfortunately common occurrence in the trade but something we will never do!

For metal bracelets we provide the size it will currently fit in the description section of this page. If this measurement is too large or too small we are able to assist in either adding or removing links. We also offer this service, post service on a at-cost basis (i.e. we don't add a margin).
