Omega Speedmaster Caliber 321 Circa 1967 105.012-66

This Omega Speedmaster Professional 105.012-66 CB is a remarkable example of a vintage chronograph with historical significance.  The case remains strong with visible facets, indicating minimal polishing over the years. The black stepped dial features an applied Omega logo and tritium hour markers that have developed an attractive patina. The ‘Dot Over 90’ tachymeter bezel is in good condition, displaying some scratches and minor indentations around the edge. The plexiglass crystal has light scratches, typical for vintage watches. The watch is fitted with a later replacement Omega crown.
