and gave him carte blanche to create an Omega tuning fork from the ground up. He came up with the now legendary Omega Megasonic 720, which was available in a limited number of guises, this being one of them...
The main difference is how the resonance of the tuning fork is converted into the ability to drive the gear train and unlike the f300's, it uses a tiny "micro motor", a completely sealed unit which transfers the resonance by creating a magnetic field which "drives" the motor. Needless to say, because the frequency is more than double that of an f300, rather than hum, they almost squeal! A great piece of engineering and extremely accurate but sadly, durability wasn't their strongest point and many an inept watchmaker inadvertently destroyed these movements simply by introducing a magnetised screwdriver too close to the micro motor, which rendered them useless. I'm glad I've got one and have had it for a number of years and it's still going strong. They pop up now and again on Ebay and my advice to any vintage Omega collector would be to get one... as long as it's working... as parts are very difficult, if not impossible, to come by...
