Manufactured in 1950, this is a fine example of the Patek Philippe Ref. 2457, a center-seconds Calatrava powered by the legendary Cal. 27SC. The Ref. 2457 combines the timeless Calatrava case of the Ref. 96—produced over many years and beloved worldwide—with the Cal. 27SC, regarded as one of the finest center-seconds movements ever made.

The symmetrical design unique to a center-seconds layout, the elegant Calatrava case with its beautiful flat bezel, and the substantial presence characteristic of center-seconds models are all perfectly balanced. In addition, the all-Breguet numeral dial unique to the Ref. 2457 further enhances the watch’s exceptional beauty, making this a truly rare and valuable piece.

The watch comes with its original buckle as well as an archive extract (Applied gold Breguet figures). Overall condition is excellent, making this a genuine collector’s item.
