Per above comments...Could also be why this price seems higher than I'd expect. Inspect carefully, those hands and movement, you should.
The watch in question is my property. These were the hands that came with the watch, including the sweep. The hour/minute hands have been relumed (purchased like this) while the sweep is original.
I could have replaced them or put vintage lume but i left it exactly as it came in my possession; and what amazes me is the short lume size hour hand compared to the rest.
I strongly believe that hands and dial are original to the watch.
The bezel / insert may be a vintage replace (1969-1990 version) ?!
A while ago i've mentioned Omega provided late 321 Speedmasters with painted Omega logo dials.
The watch in question was delivered to Hong Kong in Feb. 1969.
Some may think that most of the 145.012 ref.'s may look the same:
Most... but not all.
I was a bit intrigued myself about the dial and hands on my specimen, until i found this one (left, presented on WUS a couple of years ago):
...same bezel, same hands set including sweep, same dial. It's either a 26.559.* or a 27 mill serial number while mine is a 26.553.*
In 1968 Omega was selling both c. 321 and c. 861.
At least two other printed logo dial versions cal. 321 are known.
The ST 145.012-68 cal. 321 racing dial:
Notice the dot at 90 bezel and the sweep for a 321.
And ST 145.022-68 cal. 321
APOLLO:
Again the sweep for a 321.
Then worth mentioning this ST 145.022-68 cal. 861 applied logo dial, that was sold in April 1971. Notice the serial # 31 Mill.
Notice the dial, dot at 90 bezel and sweep hand for a -68 ref.
Then compare to this ST 145.022-69 cal. 861, serial # 29 Mill.
And finally see this ST 145.022-69
Notice the dot above 90 bezel and the sweep seconds.
In short, Omega did not follow a specific pattern in assembling Speedmasters.They went back and forward with case refs. and we sometimes see a big discrepancy between the serials and case refs. This also happens to parts like: sweep hands, dials, movement extension rings, movement dust covers, crowns, pushers and maybe others (ie. bracelets).
Finally, the price is according to Omega Mania and Isnardi, for the year ref. and rarity.
Hope this helps.
