I was looking for a birth year/month Speedy on Ebay (found one, BTW, but polished beyond recognition). I ran across this weird conglomeration: https://www.ebay.com/itm/VINTAGE-PRE-MOON-OMEGA-SPEEDMASTER-CHRONO-145012-67-SP-321-Manual-Wind-Warranty/233170327343?_trkparms=aid=222007&algo=SIM.MBE&ao=2&asc=20131003132420&meid=1e58b6d575144b518c7f4df18ecabd63&pid=100005&rk=3&rkt=12&sd=254167541324&itm=233170327343&_trksid=p2047675.c100005.m1851Purchases made through these links may earn this site a commission from the eBay Partner Network The orange hand caught my attention for $10k. Listing states it is not an Ultraman. DNN is wrong. But then I looked at the serial #: According to Ilovemyspeedmaster.com, 16649012 puts it in the 1959, CK2915-3, Caliber 321 range. If that is a genuine 2915-3 movement, it may be worth $10k just for the movement. Caseback shows 145-012SP So, is it a franken with a rare (aka valuable) movement?
I think probably this 321 might be from a seamaster chrono, no? Especially with the very early 321 movements there are issues relating to if it’s a speedy or seamaster movement.
Even if the movement is correct for a 2915-3, what is the expected wait time and expense for the missing parts. A life time and a fortune. Yes, but all the pre 105.002-62s have that.
Huh...really? I was not aware of any way to ascertain if an old 321 that normally have no extract info available came from a speedy or not. This is new to me. Any hints to your quiz?
Time is up. The 2915-3 has a unique movement ring, shown above, with two holes which seem to have no purpose.
So the proper ring and movement number range leads me to believe the movement may have started life in a 2915-3. Question is where is the rest?
Darn! I wish my guess was as close as yours. @gemini4 Thanks for the education- I had no idea! Interesting. Is this kind of movement ring only observed in the 2915-3?
I see, so I guess it might be just a 2915-3 thing. Aside from the 2915-3, in other references, are there additional clues specific to the reference that can help identify if the 321 is an original speedy movement?
I live somewhat close to the pawn shop that is selling this watch. I noticed this watch a few days ago, it "sold" already once at 8k but the listing had some different information. I was going to stop by and see if I could talk to the watchmaker who did the work to see what's up. If I get the time I will see what I can find out. There is also another clue w/ the movement to indicate pre-62 321 movement. See blue arrow.
as a point of reference, if you're ever considering a bare movement, keep an eye out for the screwed in clamps that are for seamasters, not speedmasters... Seamaster: Speedmaster: The seamaster movement hold has small cut-outs for a little clamp that's held in by the screw (highlighted in Periwinkle)
