This new release from ZF Factory is the Audemars Piguet Royal Oak 15407, available in gold and silver finishes with a 41mm case. The Royal Oak’s iconic octagonal case delivers a bold, powerful character. Rose gold is a material frequently favoured by Audemars Piguet. Compared to the imposing presence of stainless steel, rose gold carries a softer touch. Paired with the rugged Royal Oak design, it creates a striking balance of strength and elegance with an exceptionally appealing look.

It features anti-reflective treated sapphire crystal on both dial and case back, a screwed-down crown, and 50 metres of water resistance. All exterior case specifications match those of the 15400 and 15500 models.

It comes with a dark grey openworked dial, rose-gold luminous applied hour markers and Royal Oak hands. The openworked dial design removes excess material, endowing the watch with artistic styling and architectural beauty. This traditional craft demands extreme precision; the tiniest deviation may cause timing errors or compromise shock resistance. ZF Factory strikes a perfect balance between showcasing the intrinsic beauty of the mechanical movement and maintaining precision, letting viewers appreciate the charm of moving mechanics through the openworked structure.

The movement adopts an integrated openworked design alongside the dial. The balance wheel and balance bridge at the 8 o’clock position boast a lustrous golden finish that remains captivating at any angle. As the balance wheel oscillates, every gear rotates in orderly sequence, fully revealing mechanical allure. A closer inspection unveils exquisite finishing on each gear and bridge, embodying the captivating craftsmanship exclusive to haute horlogerie.

I consider this 15407 one of the better-executed openworked models. As a three-hand watch, it delivers reliable performance. Well-made skeletonised watches are rare on the market, so enthusiasts may want to take notice. Its price is reasonably set, not astronomically expensive like tourbillon timepieces.
