What does complication mean?
A complication refers to any additional function on a watch that goes beyond the simple display of hours, minutes and seconds.
Typical examples are:
- Date
- Chronograph
- GMT function
- Moon phase display
- Power reserve display
A complication can be practical, such as a date or a second time zone. But it can also be primarily decorative or traditional in nature, like a moon phase.
Which complications a watch has depends on the model and the movement fitted.
