Patek Philippe caliber 32-650 HGS PS

Manually wound mechanical movement, jumping seconds, jumping minutes, and jumping digital hours, automatic hour strike. The movement was made especially for the 5275. It consists of 438 parts, including 75 jewels and a spiromax balance spring. The hour strike can be disabled at the owners discretion. The jumping indications are not only interesting to behold, but also technically impressive, as they require a relatively big amount of energy to be stored and -in time- accurately released.
