Without a timing machine, this is tedious and complicated. And we also need to read the rates at low amplitudes so we can find poise errors. WeРІР‚в„ўve talked about how we need an amplitude of at least 270 degrees in the horizontal positions and 220 degrees in the vertical positions. The watchРІР‚в„ўs amplitude, a crucial factor in watch adjusting.Based on that, we can estimate the watchРІР‚в„ўs daily rate-how slow or fast it would be across 24 hours. The watchРІР‚в„ўs instantaneous rate-how fast or slow it is within a small window of time (e.g., 2, 4, 10, or 30 seconds) right now.Timing machines show us three things that we really need to know to make a watch run accurately: Books from the 1940s and 1950s describe them as a genuine marvel, and they were-they allowed watchmakers to diagnose faults and to shave days off the time needed for positional timing. The invention of timing machines was a huge leap for adjusting. (I doubt I could be trusted around so many 16-size Bunn SpecialsРІР‚В¦) In his great book on Illinois wrist watches, Fredric Friedberg mentions the factoryРІР‚в„ўs РІР‚Сљtiming room,РІР‚Сњ where workers kept РІР‚Сљhundreds of watches wound while they were being tested for accuracyРІР‚Сњ (p. Adjusting a watch to 6 positions was a drawn-out affair.Р”Р„ big factory would have a lot of watches sitting around, ticking merrily until the next visit to the adjuster. If necessary, the watch was adjusted again, wound, and left to sit for another day. The next day, the rate was noted, allowing a calculation of how slow or fast the watch ran in that position.

After an adjustment, the watch was set to a standard time (or its deviation was noted) and then left in a position for a day. In the old days, watch adjusting could take weeks. If you donРІР‚в„ўt have a timing machine, you really need one. Collectors of vintage watches tend to be fans of the old days and the old ways, but weРІР‚в„ўll always take time-saving inventions when we can find them.
