Omega - 121.1726 - 1950-1959

Overview
This is a distinctive Omega Genève mechanical pocket watch, showing the clean Swiss design language associated with the 1960s. The white dial features bold black Arabic numerals, an additional 13 to 24-hour scale around the outer edge, and a subsidiary seconds register at 6 o’clock. Inside is an Omega calibre 830 manual-winding movement with 17 jewels, finished in an attractive and less commonly seen copper-toned colour that gives the movement considerable visual character.
The principal highlights are the Omega Genève identity, the unusual 24-hour dial layout, and the copper-toned Omega calibre 830 17-jewel movement.
