Audemars Piguet Royal Oak Tourbillon 41mm R8F Green Dial Flying Tourb

Building a convincing 1:1 edition of the Audemars Piguet Royal Oak Tourbillon 41mm R8F Green Dial Flying Tourb comes down to two things: case metallurgy and movement geometry. APS / ZF Factory mills the chassis from solid Solid 316L Stainless Steel (Satin & Mirror Finished) (41MM × 10.4mm (Octagonal Bezel with 8 Hex Screws)) and fits the regulated APSF / ZF Cloned Calibre 4302 / 3120 / 2121 Automatic automatic movement delivering 60–70 Hour Reserve (28,800 vph).

How APS / ZF Factory Machines This Reference

Every external contact point, from the milled folding clasp safety catch to the knurled winding crown and bezel teeth, carries the tactile resistance expected of a Geneva timepiece. We inspect the dial printing, hand alignment, and sapphire gasket seating on every single unit before it ever reaches the shipping desk.
