Omega Balance Wheel Prototypes

Someone sent me the following text and pictures of these Omega prototypes! I’m indebted to them…I wasn’t aware that Omega had researched into transistor controlled balance wheel watches.

“Hi, According to the latest Omega book written by the museum curator, Omega produced a Dynatron Electrodynamic with 2 transistors in 1964. Calibre 6550 had no contacts, just electric amplitude control. 100 were produced. Hope this helps in making your site even more interesting. Keep up the good work.”


“Reading the small print, I learned that Omega gave up on them quite quickly as accuracy and longevity were often worse than a good quality mechanical movement. Never sold to the public, probably destroyed, except for a couple of them, possibly at the museum. Dynatron was the prototype”
