When the hammers strike the gongs, this membrane vibrates and acts like the sound board of a guitar, dramatically amplifying the looks of the gongs. In addition, the actual titanium case back is slightly raised to pay this membrane and contains apertures along the border to permit sounds to escape. This contributes to one of the loudest minute repeater watches we have ever heard. And the watch seems even louder when it’s worn to the wrist!At that the end of the day, the Audemars Piguet Royal Oak Concept Supersonnerie Tourbillon Chronograph watch is yet another powerful showcase of this brand’s almost breathtaking technical know-how and one of a kind design sense. It’s a thoroughly modern take on a few of horology’s oldest complications, and we could observe that in the case of the Audemars Piguet Royal Oak Concept Supersonnerie Tourbillon Chronograph view, it’s also been thoroughly improved.And should you believe all of this will not come cheap, you’d be right. Though the Audemars Piguet Royal Oak Concept Supersonnerie Tourbillon Chronograph watch isn’t a limited edition, it’s a princely price of $597,400.
The Audemars Piguet Royal Oak Extra-Thin The Hour Glass Edition is the first and only Royal Oak “Jumbo” ref. 15202 produced in 18 ct. yellow gold – arguably the most classic metal for the Royal Oak aside from steel. To go with the yellow gold case and bracelet, the dial is a dark green, with the hands, hour markers and applied AP logo also in yellow gold. And most notably, the hexagonal nuts on the bezel are also yellow gold, instead of the conventional white gold.
Made in a limited edition of 50 pieces, this has the same specifications as the regular production Royal Oak Extra-Thin, which is available only in steel or rose gold. The case is 39mm wide and 8.1mm high. Inside is the calibre 2121, which has a rotor engraved with the logo of The Hour Glass and “One of Fifty”.
