Ever since the introduction of its first pocket watch with minute repeater in 1845, Patek Philippe has been recognized as one of the great interpreters of the music of time. This is confirmed with timepieces such as the sky moon tourbillon wristwatch (with 12 complications, including a minute repeater with “cathedral” gongs) or the Patek Philippe grandmaster chime with 20 complications, among them 5 strikework functions (grande sonnerie, petite sonnerie, minute repeater, alarm with indication of the preset alarm time, and a date repeater that sounds the date on demand). Additionally, the manufacture offers the largest selection of regularly produced wristwatches with minute repeaters. Mechanical self-winding movement. Caliber R 27 PS QR LU. Minute repeater.
