I have an Omega co-axial. I have cleaned and repaird it. It is running 2o minutes fast in 24 hrs. Does anyone know how I can slow it down? Thank you!!! bobby@beadworldbeads.com or (847)776-2323 days Bobby

Hi Bobby, Without physically seeing it hard to say, I serviced a few of these a while ago, there are a number if things it could be, you say serviced how long ago was it serviced if recent I would send it back for correction I know when things go wrong with these it gets expensive fast, it may be simply contaminated hairspring would be one of the first things I would look at, there are special tools for adjusting the timing on these but by only a few seconds.

Bobby, any chance when you reassembled it you captured two hairspring rungs with the regulator pins, rather than just one?

My first thought that hairspring touching. The second would be as mention earlier. About 2 hairspring rungs instead of one. Did you [one dip] the hairspring/ Balance. Or let it go in the cleaning solution.

I did some inquiry with one of the big suppliers a couple of months ago concerning "One Dip" for hairsprings. I wanted to know if the chemicals in One Dip were capable of dissolving the shellac that holds roller jewels in place. They checked with their technical department and the answer was yes (large alcohol content). I decided to pass on buying it. I can't remember if it was Jules Borel, Otto Frei, of Esslinger. Nevertheless, be cautious when using

Hi Bob,
Several things come to me when a watch is running fast. first is like the others said with the hair spring, if you happen to get the smallest drop of oil on the hairspring, it will stick together and need to be recleaned, second is to make sure you demagnitize the movement after the service. a magnitized hairspring can stick together just like having oil on it,( thus shorting the hairspring length) when stuck together. If the hairspring is in good working order check for broken jewels in the balance, escape wheel, pallet, and train. A broken jewel will cause resistance to the balance loosing power and it will also run fast.
Hope this helps. Mike...
