Track your watches’ timekeeping accuracy
WatchCollector makes it finally easy for you to track the timekeeping accuracy of the watches in your collection!

With WatchCollector, you simply take a picture of your watch and enter the watch's time into the app. When connected to the Internet, time taken from the closest Atomic Clock time server is compared with the time you've set. WatchCollector tracks this as "Shift". The difference from the last sample is also recorded as "Drift", showing you how much your watch's timekeeping changed from the last sample. A full history of samples is recorded for each watch you want to track.

Providing baseline Atomic Time accuracy to 1/100ths of a second and sample accuracy to 1/10th of a second, you can accurately measure even high beat mechanical watches!

NTP: Network Time Protocol
Shift: Total difference between your watch and the real time
Drift: The amount of time your watch lost or gained from the last sample
