Watch making professionals for centuries relied on intricate mechanical movements to supply the timekeeping for their works of art – all of this changed in the 1960’s with the arrival of the electronic watch movements, like this Omega f300 Chronometer electric here.


The first battery powered watches, “tuning fork movements” – not to be confused with modern day quartz movements – were simply a standard mechanical balance movement utilizing an electromagnet to provide the movement’s power as opposed to the mainspring used in mechanical movements.  The era of the tuning fork movement was short-lived, replaced by the cheaper quartz movement triggering the disastrous “Quartz Crisis.”


Always an innovator, Omega created a range of electronic watches incorporating this new movement that would be named the f300hz frequency of the movement’s vibration – by the mid-1970’s, Omega – as usual – was at the forefront of oscillator-based watch technology.  The Omega f300’s are very much “hummers” – holding any of this line near the ear, it’s readily apparent why this watch is referred to as such.


One very important aesthetic characteristic difference between electric watches, with the f300hz no exception, is the very smooth sweep of the second hand, akin to the well-known characteristic of mechanical watches.  The electric watch doesn’t tick like a quartz movement, nor even the “rock sweep” like most mechanical watches – it glides around the dial, and can be captivating on first encounter.


This Omega f300 comes with a leather strap, nylon NATO strap, Pelican travel case, and springbar tool.

1970's Omega Electric f300hz Chronometer

  • DIAL: Omega-signed dial, with matching hands.


    CASE: Stainless-steel case measures 38.5mm (w/o crown, 40mm with) x 40mm; matching caseback.


    CRYSTAL: Domed crystal, no scratches or cracks.


    BAND: Light-brown leather strap, with stainless-steel hardware; this f300 also comes with a blue and gray nylon ZULU strap.


    MOVEMENT: Omega f300 Hz Tuning Fork electric movement.  A small battery powers the f300 Hz tuning fork; a miniature transducer sets a resonator vibrating at 300 oscillations per second. These oscillations are in turn maintained by an electronic circuit, which is then divided into units of time.  The vibrating resonator is responsible for the “hum” of the f300 movement.


    CROWN: Omega-signed stainless-steel crown.
