Omega Constellation Pie-Pan Chronometer Cal. 551 (Ref. 14381-11 SC) (35mm; Automatic)

A beautiful early-1960s Omega Constellation Pie-Pan powered by the Calibre 551 automatic chronometer movement. Unlike the later date models, this is the cleaner no-date configuration, with applied indices, crosshair-style minute track, Constellation script, and the applied star above 6 o’clock. The caseback reference 14381-11 SC and movement serial 18262261 place it in the classic early Constellation era.
