GUIDES
Watch accuracy guides
How well does your watch keep time, and what do the numbers mean? These guides explain the measurements Horology makes, in the app's own words.
- TIME CHECKHow to measure your watch's accuracyCompare your watch with atomic time twice, about a day apart, and you know its real daily rate, as you actually wear it.
- TIMEGRAPHERRate, amplitude and beat error, explainedA timegrapher listens to a mechanical watch tick and turns every beat into three numbers. Here's what each one tells you.
- SIX POSITIONSThe six-position test, explainedA mechanical watch doesn't keep quite the same rate in every orientation. A six-position test shows how evenly yours does.
