:
: you are correct: there are three major version
: of the Siffert (Autavia Reference 1163T; Cal
: 11 / 12 automatic, with Tachy Bezel; white
: dial; black registers; blue trim). First
: version (very rare) was marked
: "Chronomatic"; second had the
: polished steel hands; third had the brushed
: steel hands. (see the OnTheDash page that
: covers this, inked below).

: In this second version, with polished steel
: hands, the earlier ones had plain polished
: steel hands with luminous inserts; the later
: ones had polished steel hands with luminous
: inserts, and also dark (black / blue)
: inserts, between the luminous and the center
: pinion.

: your photo illustrates this very nicely.
