1966 OMEGA (Swiss) Constellation Ref. 167.021 Steel Dress Watch – 24j Automatic Cal. 712 SN 23649793


Out of stock

A lovely and classy OMEGA ‘Constellation’ Chronometer watch, this steel Ref. 167.021 with the automatic Omega 24j Cal. 712 has been professionally inspected in-house by Localtime.

Serial number 23649793 places its production in 1966. The 33mm (35mm counting the logoed crown) solid steel case is in unpolished condition. The white dial with applied indices/logo and set of hands create a wonderful contrast, especially with no date-window, which is my favourite version. Original plexi with Omega logo has been lightly polished. I have included many photos, including some closeup snapshots, just for fun. This lovely watch is fitted with a Corfam-style calf leather strap. I sell similar Corfam-style straps separately in the store under Accessories & Straps and you can also see these straps in the last photo here.

As with all the watches we handle inhouse, the listed buy-it-now price includes a 6-month written warranty from the time of purchase. Do not hesitate to contact us for any further information you might need.

Extra: Try my Localtime Corfam-style strapsLet’s face it, we all wish we could use the vintage, original type, but they are nowhere to be found anymore. If you do find them, they are very expensive or dry and stiff if they were not properly kept all these years. I have found these straps to be a good alternative to the vintage Corfam racing straps and very comfortable. They come in 2 sizes (18 & 20mm) and with 2 keepers, one of which is fixed and the other one is floating. The straps themselves are black and very comfortable. Their length is 90mm on the buckle end [including the steel buckle] and 115mm on the tail end; so not short but not too long either. I will include a pair of good quality speed pins too. Feel free to contact me for whatever questions you might have.

Important Note: Sometimes I am asked what I exactly mean with ‘professionally inspected by Localtime’. Here is my theory on vintage watches: as a purveyor of vintage watches, my effort is to always do only what is needed to the watch. I do not buy ‘junk’ watches to resell. I am choosy with my purchases and always sell watches that are, to my knowledge, authentic and in good condition. I first inspect the watch, both visually (cosmetically) and then mechanically. If I judge that the watch is not yet in need of a full service then I do not put the watch through a service which, by the way, entails a lot of risks too. Instead, I give it what I call my ‘Spa’ treatment which will include a cleaning, changing of gaskets, oiling, lubricating and mechanical testing. If the plexi is heavily scratched or discoloured and it can not be cleaned, I change it. If the crown is wrong or worn, I also change it. Now, if the watch is in need of a full service, then my ‘professionally inspected’ description becomes ‘professionally serviced’. In both cases, I mention what has been changed (if anything) on the watch and I include a written warranty with my listed price.

Important Note On Straps/Bracelets: The straps I use on my watches (leather, canvas, suede, rubber) are always brand new, unless otherwise mentioned and, in most cases, I also sell them separately in my store, in different colours and sizes. In the case of metal bracelets, if the watch is NOS, the bracelet is also unused. If the watch is pre-owned with its original bracelet, then the bracelet is also pre-owned, unless otherwise mentioned. Either way, if in doubt, please ask.
