Seems to me the 27mm serial number is way too high for a 321 movement which, IMHO, top out in the 26mm range. Correct movement should be about 24mm serial number. This serial number more fits an 861 movement. Doesn't look right to me. Buyer beware big time on this one.
Ok OB1, you got a bit of a correct point here. MWO indicates that rare 145.012-68 had 27320xxx movements which match the 321 in this 1965 Seamaster. Perhaps, this all original Seamaster, had its movement replaced in service. I don't see how else this movement belongs in a 105.005.65. I don't know the exact production years of the watch but I have a 145.006-66 Seamaster with a 2654xxxx movement number. Perhaps some one needs this movement to complete a franken Speedmaster 145.012-68. I'm confused.
It is an interesting topic. I was under the impression that the serial ranges were ranges, but not necessarily consecutive. I may be wrong, but I thought that, say within 26m - 27m, there could be seamasters and speedmasters... those numbers are high enough that an extract should be available to prove it one way or another.
..on a related note, if someone put that movement into a speedy case, how would you know (without an extract)
I don't know if this is true or accurate, but it's interesting.. http://forums.watchuseek.com/f20/omega-calibre-321-not-produced-since-1960-a-176420.html
firstly, it would only work in a 145.012-68. Secondly the , movement number is 27320233 or 288 so I would know
