Like many other watch manufacturers in the 1970s, Omega employed the ESA 9162 tuning fork movement in many of their watches. Rebadged as the Omega 1250 that we have here.
The ESA 9162 movement is often considered the “Rolls Royce” of tuning fork movements. They were designed by Max Hetzel, who had previously worked for Bulova; he was also responsible for the Accutron 214. In May 1972, ESA also released a chronograph version of these tuning fork movements; it was known as the ESA 9210 and was used in the Omega Speedsonic range of watches.
The Omega watches employing these tuning fork movements were usually referred to as the ‘Omega f300’ models reflecting the frequency of the tuning fork.
