I don't believe Omega ever produced any electrically-driven balance wheel watches, either contact controlled or transistor controlled but they they were very much involved in tuning fork watches, and had some very unique designs.

Like many other manufacturers, Omega employed the ESA 9162 tuning fork movement in many of their watches. These Omegas were usually referred to as the F300 Hz models reflecting the frequency of the tuning fork. The F300s must have been produced in the tens of thousands and are often seen on popular auctions sites today.

In contrast, the Speedsonics (ESA 9210) and awesome Megasonics (Cal 1230) are much harder to come by. Read more about them on the links to the left.

Although this website is all about electrically-driven balance wheel and tuning fork watches, I came across an Omega Megaquartz 32 KHz recently and had to buy it! Being made in 1973 and being Omegas first analogue quartz watch, it's not too out of place here.
