EEEEEEEK I hear you say!! Hold out... So yesterday I ran a serial with Omega on a very special watch, I will withhold the details of it as per request of the actual current owner. Now the serial came back as fitted to a Seamaster 145.005, but the watch in question was sold new to the present owner, it also has the original box and docs stamped by the original supplying dealer in the late 60s. It's actually fitted to a Speedmaster. This is where the issue arises. We know the watch was bought new, it has also never ever been serviced by anyone so there is no chance of any parts being changed at any service in any point in its life. Having spoken to Charles at the Omega Museum, he kindly explained that some watches in the 60s were fitted with movements destined for say a seamaster but actually fitted to a speedmaster. He goes on to say that this was due to several factors like the actual reference that the movement was originally made for was not selling well so production was stopped and the movements were fitted in other cases that would accommodate that movement. The only downside is that Omega made note of the serial number as being fitted to a Seamaster in the archives but it was actually never fitted to a Seamaster and it was ultimately fitted to a speedmaster. Now we know that the watch has been in the same ownership from new, the only time the watch has been opened is to gain the actual serial for an extract of archives. Today, I was contacted by someone who has a Straight Writing with the same issue. The movement was originally destined for a Seamaster but fitted to a Speedmaster. When you cross reference the serial it comes back as an 861 from a Speedy on I Love My Speedmaster. This makes me think just how many more are out there. It seems to be the movements from 67-69. It's clear that there is more than one speedy with this issue. We simply can't call them franken's because they left the factory like this and an extract is now not available and a refund is not an option. Interesting to know what you guys think.
