When it comes to luxury watches, few names command as much respect as Audemars Piguet. Their Royal Oak series is a testament to timeless craftsmanship and innovation. The ZF workshop has taken this legacy up a notch with their CAL.3120, a homage to the iconic AP Royal Oak 15400. This release is what many are calling the ‘extreme version’ of the beloved model.

The design features a fully integrated watch case and an octagonal porthole bezel, with hexagonal screws sitting slightly recessed into the case, closely mimicking the original. The bracelet sports that distinctive tank track look, offering both flexibility and an exquisite texture that matches the original’s fluid lines.

One of the standout features of this timepiece is the TAPISSERIE pattern on the dial, adorning it in perfectly aligned rows. This is complemented by luminous white gold 3D hour markers and Royal Oak hands, which enhance the watch’s visual appeal.

The newly developed one-piece CAL.3120 showcases a precisely positioned balance wheel at the 7 o’clock mark, ensuring perfect alignment with the genuine article. The movement includes a flat hairspring and features a gear and mainspring barrel that are not just for show—they’re genuinely functional. The watch boasts a power reserve of 41 hours, identical to the original.

With ZF’s complete and exhaustive upgrade of the 15400 model, it’s designed to make you fall in love at first sight, making it possible to own such elegance at a time when you’re ready for it.
