This Hamilton Tech Data sheet on Timing and Rating watches is a very useful part of my Hamilton service manuals that will be posted in full later. I post it here because I it can help others in our club who have reached this point in working on their watches. The Regulation chart suggests how many minutes per hour are compensated for by turnig the mean time screws. The Rating section is Hamilton's explanation of rate error that is totally separate from time regulation error.
