As 70s dress watches are really only just becoming desirable, the reference hasn’t really appeared much on the forums (twice before now) - the 70s style is interesting but definitely of limited appeal, ( hence it not appearing much on OF) and so knowledge about the value of the watch will be limited.
Dating a watch exactly is notoriously difficult.
The movt serial number places it around 1969 but a watch movt can be produced and not assembled into watches for quite a while.
A couple of years might be possible, however, 5 years is stretching a point.
An extract of archives from Omega ( not available at the moment) would tell when the watch was produced.
Alternatively, the watch’s papers or sales receipt is a way of telling when the watch was sold.
This excerpt from AJTT shows the watch was produced in 1970, which ties in with the movt date of 1969
As noted above, the 31,xxx,xxx serial number is consistent with production circa 1970, although obviously it might have been sold later. For an Omega watch produced in 1974, you would nominally be looking for a serial number in the 38,xxx,xxx range.
TBH, the style (and to some extent the quality) of Omega watches were declining as the 70s progressed as the entire industry was under tremendous pressure from the new quartz technology. So unfortunately, it may not be so easy to find an appealing birth-year Omega watch for 1974; it's just bad timing. Omega made some aggressive stylistic choices in that era, but the watches look very dated at this point, and have mainly a niche following.
Grand Seiko and Rolex would be worth a look for 1974, IMO, since they continued to produce more classically styled watches.
