The OMEGA SEAMASTER caliber 321 column wheel chronograph movement is considered one of the best vintage chronograph movement ever produced. The 321 was chosen to go to the moon in the OMEGA SPEEDMASTER. This caliber 321 manual winding movement sparkles after a recent cleaning and all chronograph functions operate like silk. The highly reflective metallic silver dial is original and looks fantastic. The hands are also original. This case has a slight light rose gold tone. The 35mm. solid 18k. gold case appears like the sides, lugs and bezel has NEVER been polished. The beveled edge of this bezel edge are very sharp! The OMEGA crown is original. This 1963 OMEGA Chronograph is truly a time capsule and was barely worn.
