Patek Philippe unveils a groundbreaking complication with the Calatrava Weekly Calendar, featuring a new semi-integrated mechanism that displays the week number alongside the day and date—an ideal tool for the modern businessman. Housed in a sleek steel case, this watch is powered by the new self-winding Caliber 26-330 S C J SE movement, designed for optimized performance. The silvery opaline dial is distinguished by exclusive handwritten-style letters and numerals, adding a unique touch. The 40mm steel case, with a height of 10.79mm and 30m water resistance, is complemented by a light brown hand-stitched calfskin strap and prong buckle, blending innovative functionality with classic elegance.
