In this video, we'll cover how to carry out a watch accuracy test with or without a timegrapher, then improve the accuracy of the watch through a process called “watch regulation”.
Timegrapher is an indispensable tool in watch repair for checking how well the movement of a watch is functioning. With it, we can determine the time deviation per day of a movement, which is used in watch regulation to adjust the accuracy of a watch.
