Servicing an Omega Constellation Electronic Chronometer f300Hz

This is an Omega tuning fork watch. I repaired this watch a year ago. I didn't disassemble the movement at that time. This time, I tried to service the movement.

The movement is the Omega calibre 1250 movement, the Omega version of the ESA 9162 movement. It uses electronic power to drive a tuning fork at 300 Hz, producing a fascinating sound (literally). The movement design is sophisticated and surprisingly simple for its performance. The challenge was adjusting the gap between the blade on the adjuster plate and the index wheel. The technical guide provides the details. Actually, it was more tolerant of imperfect adjustment than I thought. If they are not damaged and the blade is lightly touching the wheel, it will run. If the watch loses time, the contact may be too strong. If the watch gains time, the contact may be too weak. I adjusted the adjuster screw just to touch the index wheel, then I unscrewed it a bit to release the unnecessary tension on the blade. Lubricating was another question. I followed the basics of mechanical watch maintenance, using light viscosity oil for jewels and using medium viscosity oil for metal-to-metal contact points. Although this was an experiment, I was pleased with the outcome.
