A 36 month power reserve?!!! No wonder AP is so expensive.

Haha no idea why that is there, but it has been removed. Good thing is also has the correct 60 hours power reserve listed. Thanks so much for the heads up! We’d like to send you a free CC sticker for helping to make this caliber listing more accurate.

Hello I am looking for the string of a 3120 to which another AP belongs this string.

Is this movement noisy with the rotor?
