Assuming the hairspring is sitting correctly in the regulator pins, is flat, correctly coiled and clean. The balance has been correctly lubed and pivots/jewels are all ok, and it is poised ok. The timegrapher is set correctly for lift angle, beat rate etc .I appreciate that the quality of the movement and lack of wear etc are important but assume that these are at acceptable levels. What effect will beat error have, if any, on the positional timing? Is there a target beat error range that should be aimed at for good positional error? Your esteemed comments would be much appreciated.
A vintage Elgin 15/0, Gr 559. I took it down, cleaned and lubricated it and it is gaining 15 minutes/24 hours. I have looked at the HS, it appears to be perfect, clean, flat, not magnetized (de-magged the movement X 3 already), and in position between the regulator pins. Not hung on the center wheel. Correct mainspring, and balance is not knocking. I do not remember amplitude, but IIRC, it was above 22 which is O.K. by me with the movement. Please give me some ideas as to how to correct this. It doesn't seem like there are enough timing washers in the world to slow this down! Thanks, RMD
I'm really interested in finding out what main characteristics in a mechanical watch decide how much power reserve one can achieve. Can an existing watch be retro-fitted to enhance power reserve and is it recommended? I'm thinking does it impact on the other components in a watch?
I have just posted a new vid on YouTube. This one takes last weeks video a bit further and shows the basic operation of a Timegrapher timing machine.
