Omega Watches
Since the company was founded in 1848, Omega has pioneered a huge range of innovations. Britain’s Royal Flying Corps chose Omega watches in 1917 as official timekeepers for its pilots and again in 1940, RAF Pilots watches were supplied by Omega. The 40s also saw the first tourbillon wristwatch and the first of the famous Seamaster watches, whilst the 50s and 60s introduced the legendary Constellation, Speedmaster, Seamaster 300 and Railmaster. Over these years, everyone from John F Kennedy to Elvis wore Omega watches on official duties. What’s more, in 1962, astronaut Wally Schirra took his Omega Speedmaster to space on NASA’s Mercury Sigma 7 mission, and in 1969 two Speedmasters landed on the moon, worn by Neil Armstrong and Buzz Aldrin.
Description
A beautiful, completely original, unrestored and untouched Cal.30T2 gentleman’s 9ct yellow gold dress watch from 1946. The star of the show here is undoubtedly the movement, as the ultra high grade Cal.30 T2, often specified as chronometer grade, was simply one of the finest hand-wound movements ever conceived. It is an important movement in the record books, for its incredible standards of accuracy and reliability attained at all the competitive trials it entered and won.
Other notable features of this watch include its simply wonderful and highly elegant dial, which is typically 1940s, along with its beautiful 34mm yellow gold watch case.
The Dial
The original, unrestored and untouched slightly off-white dial is furnished with black 1 – 2 roman numerals, swept by unrestored blued steel ‘sword’ style hands which are all completed by the perfectly placed subsidiary seconds dial at 6. As a whole, this dial speaks of another level of quality, in keeping with the quality of the case and movement.
The dial simply carries the Omega brand and signature at the very top of the dial just below 12.
This dial is original and unrestored and has been left untouched by our restoration team due to its superb condition. Usually, we restore the dials of the watches we sell, however we decided in this case to leave it alone, due to its unusually good condition and to retain its originality and charm for those who prefer this. It also helps to contrast with almost all of the other watch dials you see on our website, which have been restored. The hands, likewise, have also been left in their original untouched condition.
Please note, studio lights, professional-grade digital cameras, and macro lenses can be very unkind to an unrestored vintage watch dial. Also the dial here measures less than 1.25 inches across, so the image you’re seeing may be between 5 – 25 times larger than the watch itself. Therefore please keep in mind you are seeing many tiny flaws which cannot be seen, or will be very hard to see with the naked eye, even under close examination. Suffice to say, on the wrist, in natural light, this dial looks much better and carries a great deal more charm than the photographs portray.
The Movement
During the late 19th and early 20th century, manufacturers and their master watchmakers expended significant amounts of time and resources in preparation for Observatory trials held throughout Europe. Unlike the watch fairs of today, these events were not intended to showcase new products. Instead, the Observatory trials focused on the science of Chronometry and the ability to make chronometers measure time precisely.
Geneva observatory trials were exclusive for companies in the Canton of Geneva, whilst Neuenburg (French: Neuchâtel) competitions were open to all manufacturers. This is why Omega and Longines set up branches in Geneva – they wanted to take part in prestigious Geneva competitions. The Omega Cal.30 was first released in 1939 and was so successful it remained in production, regularly certified as Chronometer grade, until 1963. It became famous for winning first prize ‘for Precision’ i.e. accuracy and reliability, at the Kew Observatory trials in 1946 and went on to win back to back 1st prizes at the worlds most competitive trials in Geneva and Neuchâtel throughout 1947-1951. It not only beat all comers, including Patek Philippe, but also relegated Omega’s own Tourbillon movement to second place!
As can be seen, this Omega movement looks spectacularly pristine having been well cared for and properly maintained. It is signed ‘Omega’, ‘Swiss’ and ‘15 Jewels’ with the serial number 10317289, dating manufacture to 1946.
The movement has just been fully overhauled and serviced by our vintage Omega specialist watchmaker. The watch therefore winds, runs & sets smoothly and it is keeping excellent time. Following its service, it has been calibrated and is currently running arrow straight at +11 seconds/day! This excellent for any watch of this age. These results have been verified on our electronic timegrapher instrument. The watch also has an excellent power reserve of 44 hours. We are therefore more than happy to offer 12 months warranty on the movement of this watch*.
*Please note, our 12 months’ warranty is only applicable if the full list price is paid.
The Case
The high quality Omega Swiss made 9ct yellow gold case measures 34mm in diameter, excluding the correct Omega signed winding crown. This makes this a slightly larger sized wristwatch for the period, when typical sized watches measured only 32 or 33mm diameter. The case is of a sturdy three-piece construction with a wide bezel and strong lugs.
After a close inspection, the watch case has simply required a careful clean and a gentle polish to bring it back to its current, almost as new condition. The case, the case-back and bezel are all in superb condition with almost no marks visible to the naked eye, indicating this watch has been very well cared for. The case-back is of full thickness and has never been inscribed. It is tight-fitting and presses back with a pleasing and reassuring ‘pop’.
As this is a Dennison made case, inside the case-back all is as expected and correctly signed ‘Dennison Made in England’ and ‘A.L.D’ with the case reference number 13322 and the case serial number number 43726. The case also carries Birmingham 9ct hallmarks. Dennison and Sons in Birmingham and Shackman and Sons in London, both produced top quality cases for almost all of the watch brands you see on this website.
As ever, our standard advice applies: Vintage watches should be kept clean and dry at all times.

However, if a different colour or style of strap is preferred, please let us know and we will do our best to oblige free of charge.

In Conclusion
This is a very impressive vintage Omega hand-wound wristwatch, which is ready to wear and very practical for everyday use. If treated with care, this watch will make an excellent investment or heirloom piece. Omega has always benefitted from a first class reputation for the superb quality of their watch movements and just as in the case of Longines, which have been undervalued in the past, this is beginning to show in the way Omega watches are increasing in value.
A word on our prices – We always try our hardest to acquire the very highest quality watches we can find, before restoring them to the highest possible standards. We then offer these at the fairest prices we can, taking into account our pre and post-sales care and service. This approach means we will never be the cheapest, but nor will we be the most expensive. Indeed there are some well-known stores in West London which are highly successful charging between two to three times the price you see here. We, therefore, consider our prices to be fair, given the quality of watches we have to offer.
Please note, we also welcome part exchanges. If you have a watch or a small collection for sale, please contact us as we will be happy to discuss this.
We will also be happy to Service your watch, Repair your watch or Restore your watch, all at ‘sensible’ prices. Please see here.
