Speedmaster Quartz

Speedmaster 125



The SpeedSonic has no handwound, automatic or quartz movement, but a tuning fork movement. Like the Bulova Accutron had in the 60s. The movement in the Omega Speedmaster was also developed and produced by Bulova. The movement ticks on a very high frequency by using the vibrations (360 hz in the first Bulova Accutron (cal.214, 1960)) of the tuning fork. Tuning forked watches are more  accurate than a handwound or automatic watch. The movement is powered by a 1.35 volt battery (not 1.5v like the current quartz watches, so beware!). When the Quartz watches turned up, Omega stopped producing these watches. So they were not very long in production. This makes these watches quite rare, and thus collectable. Omega managed to use this kind of movement in several of it's lines (Constellation, Seamaster, SpeedSonic).

In 1973 Omega launched a SpeedSonic which had a frequency of 300hz and it used the cal.1250/1255 movement from Omega/Bulova. Please check the following link to read all about these watches.
