Under a watchmaker's loupe, the Audemars Piguet Royal Oak Perpetual Calendar 26574 from APS / ZF Factory holds its own where ordinary replicas fail: rehaut serial alignment, dial sunburst grain, and correct pinion height. Powered by the APSF / ZF Cloned Calibre 4302 / 3120 / 2121 Automatic (60–70 Hour Reserve (28,800 vph)), it maintains a true 4Hz beat rate inside a 41MM × 10.4mm (Octagonal Bezel with 8 Hex Screws) case forged from Solid 316L Stainless Steel (Satin & Mirror Finished).



### Dial Typography, Lume Application & Clasp Mechanics


Both sides of the synthetic sapphire crystal are diamond-polished and AR-coated to keep glare off the hands. Checking the crisp click of the clasp blades or the smooth winding action of the mainspring barrel confirms that the mechanical execution is tight and deliberate.
