The sleek watches, which are available in sizes ranging from 37mm to 42mm and three finishes – 18-carat yellow gold, 18-carat white gold and a two-tone version – are infused with the Chicago-born designer’s pared-back aesthetic. This is the first time that the same design has been used for both Royal Oak and Royal Oak Offshore lines.

Instead of a Tapisserie dial – the patterned motif that appears on all Royal Oak timepieces – all five models feature a minimalist design with a vertical satin finishing and the Audemars Piguet and 1017 Alyx 9SM signatures. The fact that there are no hour-markers gives the series more of a clean look and contemporary feel.

Royal Oak

Fashioned from 18-carat yellow gold, the two Royal Oak models consist of a compact 37mm self-winding reference – this particular style is especially suitable for those with smaller wrists – and a 41mm self-winding chronograph.

The larger watch is detailed with chronograph hands at three, six and nine o’clock.

Royal Oak Offshore

The two Royal Oak Offshore models – self-winding chronograph 42mm – come in two finishes, 18-carat white and yellow gold. The chunky watch is characterised by a date aperture and chronograph hands at 6, 9 and 12 o’clock. Both iterations are fitted with interchangeable straps plus an additional black rubber strap.

All four models are designed with a sapphire crystal caseback that is engraved with the 1017 Alyx 9SM logo and the phrase “Limited Edition”.

Royal Oak “Unique Piece”

The unique Royal Oak self-winding chronograph 41mm sports a two-tone case and bracelet that combines 18-carat yellow gold and stainless steel. Other design features include a black PVD-coated gold dial with vertical satin finishing and a caseback engraved with “Unique Piece”.

The mysterious timepiece – the brand hadn’t released publicity shots to us at the time of writing – won’t be up for sale through regular retail channels. Instead, the watch will be auctioned off at the collaboration launch party and the funds raised will be donated to a programme which supports the education of underprivileged children. We can only hope the lucky buyer eventually shows it off on their wrist for social media later.
