Minute Repeater 5278 Horse

In Context

At 40 mm it is sized to the current mainstream: 40 mm is the median across every watch measured in this catalogue. The case back is open, so the movement is visible without taking the watch apart, and the sapphire crystal will resist everything short of deliberate abuse.

The movement winds itself from the motion of your wrist. 48 hours of reserve is enough to set it down on Friday evening and find it still running on Monday. At 21,600 vph the seconds hand advances 6 times a second, the slower and more audible rate of an older design.

5278/500G-001 stands on its own in this catalogue — no other reference here shares its base number. It pairs a brown dial with a white gold case. It was a limited edition. Introduced in 2025. Beyond the time it carries a minute repeater.

Minute repeater with classic gongs. Diameter: 28 mm. Height: 5.05 mm. Parts: 342. Bridges: 10. Jewels: 39. Power reserve: Min. 43 hours - max. 48 hours. 22K gold off-center mini-rotor. Balance: Gyromax®. Vibrations/hour: 21 600 (3 Hz). Balance spring: Spiromax®. Hallmark: Patek Philippe Seal.
