The Calatrava ref. 5227 is Patek Philippe's most quietly compelling dress watch, equipped with an 18K white gold 39 mm round case with a concave bezel, scalloped lugs, and an Officer 's-style case back with an invisible-hinged dust cover protecting the sapphire crystal view of the movement. New for 2026, the reference 5227G-015 pairs white gold with a salmon-colored rose-gilt opaline dial.
