Thanks for your reply which adds new light to the serial number issue and which I found very interesting. I guess it is therefore conceivable that this could be from 1965.

: Omega's serial number charts are not to be relied upon as accurate
: to within more than a few years. There are a variety of reasons
: for this.

: Omega set aside serial number sequences for production of a
: particular calibre, and did not issue serial numbers as watches
: left the factory. Slow moving calibres may have been sold years
: after the typical date range for serial numbers.

: Lemania movements, not manufactured by Omega, as the 321 was, add
: another twist. These movements would logically have been
: numbered prior to delivery to Omega, and might therefore be out
: of the typical numbering range.

: Some have put forth the story, which I have not seen confirmed,
: that Omega bought what proved to be a ten year supply of calibre
: 321s in 1959. This supposedly explains how Speedmasters with
: calibre 321 are consistently out of sequence with the
: "normal" range of serial numbers and dates of
: production. This theory seems flawed by the fact that serial
: numbers from 16xxxxxx to 26xxxxxx appear on calibre 321s from
: 1959 to 1969.

: Seamaster chronos were not apparently widely sold and might
: therefore have another reason to lag a bit behind the typical
: serial number range.
