Slide Rule

A slide rule, also known as a bezel slide rule or logarithmic scale, is a complication found in some pilot or aviation watches. It is a logarithmic ruler that allows wearers to perform mathematical calculations, such as multiplication, division, and unit conversions, directly on the watch dial.

How it Works: The slide rule is integrated into the bezel of the watch and can be rotated to align different logarithmic scales with each other. By aligning specific numbers on the inner and outer scales, the wearer can perform various mathematical operations and conversions quickly and accurately.
