The Classique 5717PT/AS/9ZU, seen from the bench

The Breguet Classique 5717PT/AS/9ZU features a 43mm platinum 950 case, the densest metal in haute horlogerie, paired with the manually-wound caliber 77F0 developed in-house with 3 Hz frequency and approximately 50 hours of power reserve. The dial showcases a guilloché sunburst pattern, drop indices, and Breguet hands within a pierced bezel, while the 24-hour function with independent adjustment offers practical utility for the traveler. The curved lugs are proportioned for an 18mm strap width, integrating the watch's refined aesthetic with precise lug-to-lug geometry.
