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.
Thank you so much for watching my video. This is non-professional work. I really appreciate your likes, suggestions, advice, and comments. I hope you enjoyed my restoration. If so, please subscribe to my channel!

Very good Video. Omega was trying hard to achive better accuracy , but without Seatch Omega will not live.
Miraculous that calendar wheel wasn’t broken!
Do you service these? Are you in Japan? How can I contact you? Thanks!
Quality !
That was a very interesting video. I had no Idea that the inside of a watch was so Intricate. I have an Omega Constellation Electronic Chronometer f300Hz watch that at one time ran but does not anymore. I made the mistake of bringing it to a regular jewelry shop and they had it for two weeks. They got back to me and said they can't work on the Omega and that I should send it off to Omega for servicing. I wish I had done my research prior to letting those clowns near my watch. This is watch that is worth fixing but not sure where to go. Anyone have any suggestions?

Even an experienced watchmaker cannot fix the watch without parts for repair. You'll need to find a "tuning fork watch repair" specialist. They will have the required parts and skills to revive your watch. I found some of them in the Internet, but never have tried. Good luck!
Thank you for this video, I have several watches with this movement. I would have liked to see more information about lubricants used - you described what you used for a few parts but not all. I also was expecting some reference to the clutch, but you just washed it in benzine/ultrasonic and put it back in the movement without apparently lubricating it.

Oiling can be controversial so I don't mention too much usually :) I loosely referred to the Omega technical guide but didn't do as described because it was for the 1970s oils. For index wheels (cap jewels), I used a quartz watch oil. Since I'm a big Seiko fan I used Seiko AO-2, Moebius 9000 will be more common. I used Seiko AO-3, which is a medium-heavy viscosity oil for other jewels. For the friction wheel, the technical guide instructs to oil it with Molybdene lubricant. I hate Molybdene lubricant because it can wear parts and dirty the movement so I didn't use it. A kind of grease whould be the best for the friction wheel, but I put a tiny amount of AO-3 on the friction point.

@@vintagewatchtinkerer Many thanks for your reply. 😎
would like to know more about adjusting pawl and index fingers using the gauge.

Thank you for comments. The watch is running well after the service so far but I'm still learning about the movement. I bought another donor movement for practice. I'll share my experience if things go well.
Hello. the video is good. I have the same watch and it is fast by 6-7 seconds a day. please tell me how they can adjust their progress? or if there is a video, please share the link.

This site has a link to the Omega 1250 Technical Guide in this site. watchrepairinfo.com/techman.htm It mentions how to adjust the rate. I hope it helps you.
