Since the company was founded in 1848, Omega pioneered a huge range of innovations. Britain’s Royal Flying Corps chose Omega watches in 1917 as its official timekeepers for its pilots. Again in 1940, RAF Pilots watches were supplied by Omega. The 1940s also saw the first tourbillon wristwatch and the first of the famous Seamaster watches, whilst the 1950s 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.
Here we have an early Omega Seamaster Calendar in 18ct pink gold with a rarely seen matching pink dial. This substantial case is of a robust design and carries the first non-bumper, full rotor automatic movement, the Cal.503. This was a very expensive watch when new, being one of very few 18ct pink gold Omega Reference 2849SC-2 models produced. Having recently been sympathetically restored, this particular watch is in tip-top condition from every aspect.
As far as we know, pink dials were only available on pink gold Seamasters in the 1950s, therefore this deluxe dial would have made this a very special watch when first produced. The dial carries applied pink gilt ‘spearhead’ hour indices, matched with the original and restored pink gilt ‘dauphine’ hands, all of which look wonderful against the pink gold case. This superb dial catches the light beautifully, as we have tried to demonstrate in the photographs. It is typically 1950s, effortlessly classic, elegant and stylish.
As this is a Seamaster Calendar, a date window at 3 is delicately framed in pink gilt to match the rest of the dial.
The dial is signed with an applied gilt Omega brand, with ‘Omega’, ‘Automatic’, below, ‘Seamaster’ and ‘Calendar’, with ‘Swiss Made’ at the very bottom.
This is the original dial which has been restored to the highest standards by our dial restorers, which are considered to be the best in the U.K.
The Omega Cal.503 is the ‘Date’ version of the Cal.505. Each is considered to be Omega’s first full rotor automatic movement since they are of the same family. This movement was also used in the top of the line Omega Constellation and is so highly efficient, with a 46 hour power reserve, that once set and on your wrist you will never need to wind it even if you leave it on the bedside table over the weekend. Indeed the 500 series has proven over time to be the most precise and indeed the most celebrated movement series in the history of the Omega company. The success of the series 500 owes much to its tremendous reliability and a number of ingenious developments surrounding the self-winding mechanism.
This very high grade beryllium-bronze movement is, as can be seen, in totally pristine condition. The movement has just been fully overhauled and serviced by our vintage Omega specialist watchmaker and is calibrated and running within +14 seconds/day, which is excellent for any watch of this age. We have checked the test results on our electronic watch timegrapher and therefore have no reservations in providing 12 months written warranty with this watch.
The movement is signed ‘Omega Watch Co Swiss’ and ‘Twenty 20 Jewels’ and carries the serial number 15888501, dating this watch to 1957.
Please note – our 12 months’ warranty is only applicable if the full list price is paid.
An early Omega Seamaster in such fine condition as this, is a rare thing in the vintage watch market, especially in 18ct pink gold. This very lightly polished, large and noticeably heavy case with very solid swept-back lugs measures 34mm in diameter, excluding the correct, early Omega signed crown. The case is in amazing condition showing no signs of wear visible to the naked eye and even under a loupe it is very hard to fault.
This watch was one of the first to carry the Seamaster motif on the case-back which here is well defined, indicating this watch has only seen very light use. It is of full-thickness and has never been inscribed. Inside the case-back all is correct and as expected: signed ‘Omega Watch Co.’, ‘Fab Suisse’ and ‘Swiss Made’ and with the Omega model Reference 2849SC-2 and Swiss Geneva 18ct hallmarks.
Although the rubber seals have been replaced, and this watch was originally specified as water-resistant, this has not been tested and it is not guaranteed.
As ever, our standard advice applies: Vintage watches should be kept clean and dry at all times.
The Strap & Buckle
The watch is fitted with a tan brushed leather strap and pink gold-plated Omega buckle, which we feel finishes this watch perfectly. 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. We carry Tan, Conker, Dark Brown and Black in stock in plain padded leather, crocodile skin or lizard skin. We can also obtain most types and colours from our partners at ‘Watch Obsession’ within 48hrs. Please take a look at their wonderful range of 18mm straps if you wish here.
Box and Papers
Although there are no original papers with this watch, the reference numbers, markings, signatures and hallmarks are all correct, dating this watch to 1957.
Detailed particulars will be included with our purchase receipt for your interest and security. A separate insurance valuation for the replacement value of this watch will be provided at the time of sale along with our unique ‘Lifetime Authenticity Guarantee’ which states: “If this watch proves to be anything less than 100% genuine, authentic and original, a full refund will be given at any time”.
A vintage Omega presentation box, as shown in the photographs, is included in the sale of this watch.
This is an outstanding example of a rare pink gold Omega Seamaster Calendar automatic dress watch with the highly regarded Cal.503 movement. This is of a very high grade and on a par with watches far more expensive than this. Indeed, when new this watch would have cost more than the equivalent Rolex of its day. Omega Seamaster watches are highly collectable and the rarity of this watch means the value will always remain strong. This watch will also make an excellent investment and family heirloom piece. Even though vintage Omega prices have risen markedly recently, we feel fine examples such as this still remain undervalued. As each year goes by and the world market for vintage watches expands, availability will become more limited, so prices are surely destined to climb ever higher!
A word about 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 inevitably means we will never be the cheapest, but nor will we be the most expensive. Indeed there are a number of well-known stores in West London which are very 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.
We are happy to accept PayPal as this is the quickest method of payment. However, if you would wish to pay by bank transfer, we will be pleased to pass on a 3% transaction saving to you.
