Bathyscaphe Quantième Annuel

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.

An annual calendar is a watch complication that automatically adjusts for months with 30 or 31 days, requiring manual correction only once a year at the end of February. This feature is more complex than a simple date display and offers a balance between complexity and practicality, making it a popular choice among watch enthusiasts.
