@MSNWatch Many thanks for the reply. I really appreciate that. You are right I do have some concerns but I did not want to colour any initial feedback, plus I realise that I am biased (and ever hopeful).
100% agree regarding the case finish / past polishing.
In terms of the components matching is it
unequivocal that this watch has been made up from parts and if so, what watch types contributed – what have I got here?
As mentioned, I have concerns but the watchmaker who serviced it (normally pretty good) did not flag anything and gave me a fairly high estimate letter for insurance purposes. They also confirmed all parts are Omega original.
I have also been told Omega did play a bit fast and loose with hand/dial combinations back in the day so is there any possibility (even a small one) that this is original? Also did the CK2451 have many variants (-1,2,3,4 etc) / how was that recorded. It was in production a while I believe. I have struggled to find much data.
I have seen a few pictures of watches from the era (late forties / fifties) - some examples below...which look similar and proport to be all original (including steel/gold combinations which is what first got me worried on this watch / possible re-case)
I might be clutching at straws here but any extra info / thought from the forum appreciated.
