Here we have a rare Omega Seamaster ‘Oversize’ Day Date in 9ct yellow gold from 1970.  At 37mm, not including the original Omega crown, this is by far the largest Omega Seamaster manufactured until this date. Typical sizes for this watch were 34 and 35mm and occasionally 36mm. This is also a substantial case, similar in fact to the design of a Rolex Day Date but larger!  This watch also comes with its original Omega 9ct Bracelet which is integral to the watch. The watch and bracelet are in amazing condition leading us to believe this watch has led a charmed life!


The retro style is classic 60’s / 70’s which is very popular and has been for the past few years. The gold dial with gold batons is inlaid with black Onyx. The ‘stick’ hands are similarly inlaid with Onyx. This is the original dial which has been restored to the highest standards. The date at 3 o’clock is advanced by a quickset mechanism activated by pulling the crown past the hand set stage. The watch glass has been replaced with the correct Omega part with the Omega sign in the centre which can just be picked out in certain light.


The very high grade Cal.752, 24 Jewels movement, is on par with watches of twice the price. The watch is signed Omega Watch Co, Swiss with the serial number 29,463,xxx dating this watch to 1970. This is the same movement as used in the top of the range Omega Constellation of the same period and is very highly regarded, accurate and reliable. Here, the movement is in absolutely sparkling condition and in fact is as good as the day it was made! We have tested the movement following a full service and it is running within +5 seconds / day which is outstanding for any watch of this age. We will be pleased to provide 12 months warranty with this watch but this will only be included if the list price is paid.

Watch Case

As mentioned above, the 9ct solid gold case is very large and substantial at 37mm, not including the original Omega crown. The watch case is in immaculate condition with no marks, scratches or dings visible to the naked eye. The 9ct yellow gold of this particular watch has a particularly attractive antique hue which you do not see on a modern gold watch.  This is hard to replicate in the photographs but be assured it looks wonderful in real life! The wide flat bezel is also interesting on this watch and exemplifies the size of the watch. Inside the watch case-back is signed Omega Watch Co with the reference 1665032 along with London UK 9ct hallmarks from 1971 indicating the year the watch was imported and probably first sold in the UK. This watch case was waterproof when new and all the rubber seals have been replaced. However this has not been tested and we recommend all vintage watches are kept clean and dry at all times.

Bracelet & Buckle

The original integral Omega 9ct gold bracelet is also included with this watch. It is in amazing condition with no marks or damage. It is adjustable to three positions and is perfect for an average man’s size wrist of between 18 to 20 cm or  7.5 to 8 inches.

Box and Papers

Although there are no original papers with this watch, the numbers and markings are all correct, dating this watch to 1968. A fully detailed written receipt, our 12 months warranty* and our Vintage Gold Watches ‘Lifetime Authenticity Guarantee’ will be provided on the date of sale. A separate insurance valuation for the replacement value, will be provided and a vintage Omega presentation box will be included in the sale of this watch.

In Conclusion

This is a splendid example of the iconic Omega Seamaster watch in a rarely found 37mm case. The movement is of a very high grade and on a par with watches far more expensive than this. Indeed when this watch was new, it would have cost more or less the same as the equivalent Rolex Day Date. Omega Seamaster watches are highly collectible which along with the reasons above, means the value will continue to rise.
