A secured movement is a watchmaking innovation designed to protect delicate mechanisms and ensure lasting precision. By preventing accidental damage when setting the watch, it enhances reliability over time. At Blancpain, secured movements are a hallmark of our craftsmanship.

A moon phase complication tracks the 29.5-day lunar cycle with a rotating disc beneath the dial, driven by a 59-tooth wheel. It blends function with poetry. Blancpain is renowned for refining this feature, combining precision, tradition, and elegance in every moonlit display.
Small Seconds
A small seconds complication refers to a watch design where the seconds are displayed on a smaller subdial, typically positioned away from the center of the main dial. This feature adds a touch of elegance and precision to the watch, distinguishing it from those with a central seconds hand.
