A beautiful example of a fully restored Cal.283 gentleman’s 18ct gold dress watch from 1955.

At 36mm, this is a very large watch for the period and so is considered an Oversize watch by the standards of the time. This watch has seen lots of care and very little use and is therefore in superb condition. It also features a beautifully restored silver-white ‘2 – 4 – 6 – 8 – 10’ dial, but what lies beneath, is a landmark movement in Omega’s development. The Omega Cal.283 was a development of the tremendously successful Cal.30 series movement. This is simply one of the finest hand-wound watch movement designs ever conceived. It is also 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. See below.

The quality of its movement and sturdiness of the watch case makes this a perfect hand-wound vintage watch for both evening wear and everyday use.

The Dial

The silver-white dial is furnished with applied ‘dagger’ hour indices and ‘2 – 4 – 6 – 8 – 10’ Arabic numerals, with art-deco influences. The dial is swept by the original ‘Dauphine’ style hands which have recently been restored to the almost as new condition you see here.

The overall dial design speaks of a level of quality and confidence, in keeping with the high quality of the case and movement.

The dial simply carries the Omega brand and signature, with ‘Swiss Made’ at the very bottom. A new lens has been fitted as part of the restoration.

This is the original dial which has been restored to the highest standards by the best dial restorers in the UK.

The Case

The high quality Omega Swiss made 18ct yellow gold case measures 36mm in diameter, excluding the Omega signed winding crown. This makes this an exceptionally large wristwatch for the period, when typical sized watches measured only 32 or 33mm diameter. The case is of a sturdy three-piece construction with 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 also tight-fitting and presses back with a pleasing and reassuring ‘pop’.

Inside the case-back, all is correct and as expected; Signed ‘Omega Watch Co’, ‘Fab Suisse’ and ‘Swiss Made’, with the case serial number 11411881 and the model number 2686, along with 18ct Swiss Geneva hallmarks.

As ever, our standard advice applies: Vintage watches should be kept clean and dry at all times.

The Movement

The Omega Cal.283, 17 Jewel movement here forms part of the Omega 30mm series first released in 1939, which was so successful it remained in production 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! The continued success of this calibre was due to its precision and resistance over time, its easy regulation and the simplicity and logical design of the movement that made it a favourite of watchmakers.

As can be seen, this beryllium-bronze movement looks spectacularly pristine, having been well cared for and properly maintained. It is marked  ‘Omega Swiss’ and ‘17 Jewels’ with the serial number 14541021 which dates manufacture to 1955.

The movement has just been fully overhauled and serviced by our vintage Omega specialist watchmaker and the watch therefore winds, runs and sets smoothly and is keeping excellent time. Following its service, it has been calibrated and is currently running arrow straight at -10 seconds/day! This excellent for any watch of this age and has been verified on our electronic timegrapher instrument. The watch also has an excellent power reserve of 45 hours.

The Strap & Buckle

A new, high quality Hirsch Ascot brown leather strap has been fitted, along with a gold-plated Omega buckle.

The Box and Papers

Although there are no original papers with the watch, the numbers and markings are all correct, dating this watch to 1955.

The vintage Omega box shown in the photographs is included in the sale.

In Conclusion

This is a first-class example of a highly collectable and highly practical vintage gold watch from one of horology’s most famous names which will provide an excellent financial investment as well as be something to use, wear, treasure and enjoy! This will make an excellent evening wear dress watch as well as a practical highly accurate and reliable timepiece to use on an everyday basis.

Vintage Omega watches are highly collectable and the rarity of this watch means the value will always remain strong. This watch will make an excellent investment and family heirloom piece and 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!
