What is the main function of the minute repeater complication?

The main function of the minute repeater complication is to chime the time on command. This intricate mechanism allows the wearer to simply activate it, typically by pressing a pusher or a slide on the case, which triggers a series of chimes that indicate the current hour, quarter hours, and minutes. This feature is particularly useful in situations where the wearer cannot easily read the time, such as in low-light conditions or at night.

The minute repeater is celebrated for its craftsmanship and complexity, showcasing the watchmaker's skill more than many other complications. It enhances the functionality of a watch by providing a tactile and auditory reminder of the time, elevating the overall experience of wearing a timepiece.
