What does Hi Beat mean in watches?

Table of Contents

In a high-beat watch, the lever and escape wheel have more contact with each other than in a low-beat watch. This means faster wear and tear, shorter power reserves, and more frequent maintenance – and these are not at all in line with consumer demands for less hassle and longer intervals between services.

What is a Hi beat?
