Hello one and all! My name is Mike and I am a past "lurker" to this site and thought it was time to officially join. I am very new to the watch repair scene but totally fascinated and curious with the horological world. So thank you in advance for the advice and remember, "keep 'em tickin!!"

      Murks, The rate and amplitude look OK, and the amplitude should improve once the oils you have used get a chance to move bed-in, also I notice that you are using default 52 degrees for the lift angle, if you get the real lift angle (assuming it's not actually 52) this will change your amplitude - maybe higher, maybe lower. I notice that the beat error is a little high, but not crazy high. At the risk of upsetting the purists, if the balance has an adjustment arm I would go ahead and try and get this <0.3 ms, but if it does not have an adjustable arm then I would probably leave well alone. Just my opinion.

      Epilame / Fixodrop

      By Waggy · Posted

      Maybe I'm over simplifying this and I'm a little late to the discussion, but just by my looking at oil when I use it on a treated cap jewel  the oil stays in one nice bubble, but when I don't it spreads out to the edges of the jewel. I'm not sure (but could well be wrong) but the analogy of a waxed car and rain is accurate in this case, the wax is very hydrophobic and repels the water, however, the process epilame works by is a different physical process based upon cohesion/adhesion (oleophilic) not repulsion (oleophobic)  at least as far as I have read/observed. If one were to use a oleophobic substance equivalent to wax (hydrophobic) then one would need to create a donut shape to fence in the oil, however if one used such a strategy with a epilame which is oleophilic then the oil would sit on the ring of the donut and not in the 'donut hole', exactly where you don't want it. Even if the oil is smeared then the oleophilic epilame should pull it back to the center (see diagram below). Reference For interest the chemical in epilame is 2-(PERFLUOROHEXYL) ETHYL METHACRYLATE, CAS NO: 2144-53-8

      Looks lint the teeth on the hour wheel aren't meshing with the teeth on the calendar intermediate wheel, maybe the hour wheel is sitting on top of this instead of meshing?

      If the oil drop was freely standing on an epilame treated cap jewel it could easily slide off if you knocked the watch hard but the balance pivot keeps it in place.
