Retrograde refers to a specific type of watch complication where the hands or indicators move in an arc rather than a full circle. In this mechanism, the hand travels along a predefined path, typically a segment of a circle, and upon reaching the end of its scale, it instantly jumps back to the starting point to begin its journey anew. This feature is often used for displaying various functions such as the date, day, or even seconds, providing a visually dynamic and engaging way to present information on the watch dial.

The retrograde display is appreciated for its aesthetic appeal and the technical challenge it presents to watchmakers. It requires precise engineering to ensure the hand's smooth movement and accurate return to the starting position without any lag or misalignment. This complication adds a layer of complexity and sophistication to a timepiece, often found in high-end watches where craftsmanship and innovation are highly valued.

Retrograde displays can vary in their design, with some watches featuring multiple retrograde indicators for different functions, enhancing both the functionality and the visual intrigue of the watch. This complication exemplifies the blend of artistry and technical prowess in horology, making it a sought-after feature among watch enthusiasts and collectors.
