The "pre moon" Omega Speedmaster ST 105003
The pictured Omega Speedmaster is the fourth model produced by the manufacturer since 1963 for a short period of time. An original advertisement we have in our documentation, and the "Omega SAGA" book indicate that a model 105002 has existed. Until now, we never saw this model neither for sale, nor on some pictures.
The 105003 is the last version using a symmetrical round shaped case, without any crown or pushers protection. The sample pictured, serial number 20'521'652 was delivered in Paris , the 7 th of October, 1964.
The upper line pictures show this watch before its complete rejuvenating process by Omega factory.
From a collector point of view, the following question is very delicate to ask : is it better to keep an old original watch in its "as is" condition, or to refresh it ?
We personally prefer untouched, original watches. If replaced parts are from same era, and not just "genuine", recently built spare parts, we consider that the watch retains most of its collectible value. Sometimes, however, there is no real choice. You have to refresh. In this case, the best way is letting the factory do it for you. If you possibly can, it will be a must to tell the factory exactly which part you do want to be replaced, and which part you do not. For example, knowing that old Tritium is now forbidden and mostly replaced by "Superluminova", freshly painted hands, and dial indexes will be bright white, compared to the original old mellow yellow.
Same concern about bezel, crown or push buttons, which will be replaced by more recent versions…
The particularity of vintage Speedmasters is that during its production time, many subtle details change from batch to batch. The list could be very long indeed. We can note some several shape changes in the "S" and the "r" of Speedmaster, hands design changes, different pushers and crown diameters, logo on the crown, logo on the dial, bezel diameter and scale, and so on. Even the dial black colour has known variations.
In brief, the Speedmaster collector should be well advised about all these details before purchasing the sample he truly wants among the many others he could take a look at. The very first thing to do is contacting the Omega Museum in order to check that the serial number of the movement does match with the model you want to buy.
On the CK 2915 album page, we well illustrate this in showing what you have "not to do", as we unfortunately did…
