How to Regulate an Automatic Wristwatch - Watch and Learn #25

In today's video, we demonstrate how to regulate an automatic or mechanical wristwatch. First, we explain the difference between regulation and adjustment. These terms are often used interchangeably, but they have quite different meanings. Regulation simply means slowing down or speeding up the movement.

We will use a timegrapher to assist in timing the watch, but it is not necessary. All you truly need is a pointy tool and something to remove the caseback. If you have a well running watch, you can regulate it to be more accurate if desired. Or, if you just want some knowledge on how to do it, this video will help you.

Lastly, we will put a Rolex Yachtmaster on the timegrapher to show you how an adjusted movement performs.
