Will Royal Oak 26240OR.OO.1320OR.05 APS Factory Audemars Piguet Replica Watch customized caliber passing waterproof testing
Under a standard professional watch air pressure tester, a 30 to 50 meter (3-5Bar) static vacuum test passes no problem. The Royal Oak 26240OR.OO.1320OR.05 APS Factory Audemars Piguet Replica Watch doesn’t lose inner case space to the complex integrated movement — thickness and internal gaps are precise, and with the flat fluorine rubber gaskets on the bezel and caseback at original specs compressing, it holds a stable airtight reading in a dry vacuum test, no pressure loss alarm.
Why is a custom movement directly related to water resistance?
If the movement size doesn’t match the case, the crown stem often gets tilted under force and damages the waterproof tube. The integrated movement gives the APS version precise axial concentricity, so when the crown is pushed in and locked, the gasket is pressed evenly, and the screw-down crown seal is naturally flawless.
