PERPETUAL CALENDAR

Uncluttered aesthetics

This ultra-thin self-winding perpetual calendar is distinguished by its round Calatrava-style case with finely scalloped decoration running from case-middle to lugs and accentuating the watch's elegant silhouette. The rose gold version features a lacquered ivory-toned dial, with hollowed counters creating a beautiful multi-level raised effect.
