Glossary

Bicompax is a term used in watchmaking to describe a type of chronograph display layout that features two sub-dials symmetrically arranged on the dial. Typically, these sub-dials are located at the 3 o'clock and 9 o'clock positions on the dial, with the chronograph minute counter located at 3 o'clock and the running seconds sub-dial at 9 o'clock.

The term "bi" in bicompax refers to the fact that there are two sub-dials, while "compax" is short for "complex" or "complicated". The bicompax layout is a popular and classic design for chronographs, and is often used in vintage-inspired timepieces.
