  1. So for continuing education on timekeeping 24 hours later back on the timing machine again. As the amplitude decreases errors in the timekeeping increase especially positional errors. Then the weird part the first watch I had on the machine one of the numbers looks really weird so I highlighted that for you. If you look at the graphical display you'll see there was a problem with the waveform? But run the test again the problems gone? Any time I get really weird timing I take the watch to another machine at work. It does a time plot currently set to 16 minutes. What it does it lets you see the effect of the gear train power transmission fluctuations. Properly engineered watches have relatively even power distribution unless there's a wheel that has a defect. The Seiko watches seem to have a defect perhaps. The perhaps is because these are cheap watches and a defect like this will average out.

  2. Some fluid will evaporate, so the cover you need must be airtight. Lids for the jars can and do come available on ebay.

  3. Personally I'm impressed that he managed to make another clock about 200 years after he died. I love the key handle, just like a cheap alarm clock and that the movement is French (If you believe the writing) I'm sure one of the greatest English clock makers wouldn't have a problem having his name applied to a French clock.
