A true holy grail for any Omega collector who is ready to take the next step; the CK2998-4. No crown guards, pre-professional, straight lugs, DON, Cal.321, Alpha hands and sub-dial hands…you name it! Scroll down to read more.







An exceptional Omega Speedmaster dating back to 1961.
This is a stunning ref. 2998-4 execution in great shape.

This is a truly honest example coming from the first owner (if you exclude us, the dealer) who recently passed away, he bought this watch new in shop back in 1962 on his vacation in Abuja, Nigeria

With original 7912 flat-link bracelet and the correct No. 6 end links. Bracelet is correctly dated from the second quarter from 1961.
Just like the watch, the bracelet is in good condition with little stretch and powerful spring links.

This reference, just like the Ed White, has the desirable pre-professional dial with stepped sub-dials. The lume of the hour markers has faded a bit but in a stunning way in our opinion with the colour changing to a greenish orange tint.
The stunning dial shows an almost invisible fade.

Original set of ‘Alpha’ hands being the most recognizable and stunning characteristic of the reference 2998. Stunning orange patinated lume filled hands and rare ‘Alpha’ sub-dial hands which are not often seen with the 2998-4.

The original DON bezel has no distinctive damage but a nice even faded edge. There is a tiny dent between the 75 and 80 marker on the left side where the watch must have had a blow sometime in the past 60 years. Original 4mm short pushers and old logo omega crown.

The case with straight lugs and stepped screw down case back has some scratches here and there but nothing unusual. We have not polished this watch and don’t believe the first owner did but we can’t be 100% sure.
The speedmaster logo and line are clearly visible.

The 321 caliber movement is clean and runs great and accurate. The serial number is the correct 17.7XX.XXX. Antimagnetic protecting cap is present.

Overall great condition and a truly original historical piece that has not been messed with. If you wish to receive more information or additional pictures please let us know and we’d be more than happy to help.
