did1680 raises a fascinating question about the case variations of the Omega Speedmaster reference 105.012, challenging the common belief that only two main lug types exist. By presenting images of two 105.012 models with subtle yet distinct case profiles, he invites the community to explore whether these differences are original or a result of other factors, sparking a deep dive into Speedmaster case history.
Hi all,
Contrary to what one might think there has not been only two types of case for speedmaster, straight lug and lyre lug.
The final shape emerged with 145,022 and not 105,012.(information oméga)
As you can see from the picture, these two 105,012Â (Â merci Pierre )are not quite the same case. These differences are not related to polishing.
Have you ever noticed these differences, you know if is it the same supplier?
If you have some information about case...
lots of thanks for this great forum
Oups sorry for my english...but my french is better !!!!

is it at all possible that its a 105.003 with a 105.012 caseback? there's no mention in any of the books about this watch and in fact they distinctly state that the 105.012 is the first with assymetric case with curved lugs. the first pics are interesting. it is entirely possible that they had 2 case makers, we all know that the history of Omega throws up some very odd curved balls. it doesnt matter how much we research there is always something new coming up that we didnt know. best Graham
An here's a lyra-lugged just a few S\Ns up the line from the first one in my previous message (it was 22,824,483, this following one is 22,824,329, delivered in Zurich on 29 December 1964: Researching this, recently, I have found a few examples on the net… Is it possible that around the end of 1964 / beginning of 1965, Omega assemblers picked somewhat more often from the so-called "parts bin", and that parts of the 105.012 and 105.003 cases got mixed & matched?
i think that the 'parts bin' theory is very possible, but do we have any evidence that the case backs are original to the cases? its is entirely possible that they became damaged in some way and were replaced with later ones. who knows? the wonderful mysteries of Omega :)) best Graham
;-)
…were the manufacturers of both straight-lugged and lyra-shaped 105.012 cases I've seen.
with the 105.012 caseback are put togethers. I think it is more likely that the marriage of the two happened after the watch left the factory.
