The internal bezel on the Canford works in the same way as the external bezel on other watches, and is used to time events lasting up to an hour.

It's beautifully simple to use. Turn the upper crown to rotate the internal bezel so that the triangle points to the tip of the minute hand.

Then, as time passes, you can see how many minutes have elapsed by reading the internal bezel.

If you want to see how that works, here's a little time-lapse video we shot that shows how it works.
