The sound was actually louder on the wrist than off, due to the fact that the gongs came mounted on a soundboard covered by a caseback with openings. To this day, this is one of the most creative and rebellious (also, very efficient) watch complications ever made.
The fact that AP was bold enough to make a wristwatch of stainless steel when everyone else was using gold helped set the Royal Oak apart, eventually earning it the distinction of the world’s first luxury sports watch. “Across its nigh on 50 years of its existence, this modern horological icon upholds the innovation and excellence embodied by Audemars Pigue,” AP says.
The Royal Oak Supersonnerie is making a comeback in an updated and very limited edition. Audemars Piguet will be making and selling 40 items in total: 20 for the blue Grand Tappisserie dial and 20 for the black Grand Tappisserie dial. They come in two options: titanium case on titanium bracelet (or blue alligator leather strap), or platinum case on black alligator leather strap.
The Grand Tappisserie is what AP calls the proprietary pattern on the dial of the Royal Oak watch. Each item stands out for the uniquely shaped bezel, attached with 8 hexagonal screws in what could be described as a gorgeous, very masculine study in geometry.
With the AP caliber 2959, Supersonnnerie comes with 72 hours of power in reserve and is water resistant at up to 20 meters. The titanium version costs $321,700, while the platinum one is more expensive at $386,600.
