At 9.4 mm high, this is the thinnest minute repeater today. Also, the cushion-shaped case is also water-resistant to 30 m, which is unusual for a minute repeater with a slide. This is the second striking watch from Piaget, the first being a grande et petite sonnerie developed by FP Journe for Piaget in the nineties.
Inside is the in-house 1290P calibre, which stands at only 4.8 mm high – that is remarkably slim. Built on the 1200P ultra thin movement, the minute repeater movement is a micro-rotor automatic, with a 40 hour power reserve. Its thinness means many of the components are miniscule; some wheels, for instance, are just 0.12 mm high, while a human hair measures 0.08 mm. This makes assembly much more challenging. One consequence of the ultra-thin construction is the downward action of the repeater slide, in contrast to the conventional upward slide.
The repeater chimes in the fifth octave, at G sharp for the hours, and the minutes at A sharp. The loudness of the striking is 64 decibels, which is very audible and similar to the Jaeger-LeCoultre Master Minute Repeater and last year’s Rotonde de Cartier Minute Repeater Flying Tourbillon. Though the watch I saw and heard was a prototype, it still sounded good, and I expect the final product to score high marks. Though the case is large at 48 mm, as much material as possible was removed to maximise resonance and sound transmission. To that end, the movement is secured to the case at four points, while the gong mount is screwed to the movement as well as the case.
Because the watch has a sapphire dial, all the workings of the repeater are visible. Everything is finished to a high standard; though it has to be remembered Piaget movement finishing in general is excellent.
I have always liked the Emperador Coussin case, even with a large diameter like this it remains elegant. When paired with ultra-thin movements as is the case for Piaget, the cushion shape sits very well on the wrist.
The Emperador Coussin repeater is a limited edition of 10 pieces in rose gold, with an estimated retail price of approximately CHF250,000, or about USD270,000. And to close with some interesting historical trivia: this is not the thinnest minute repeating wristwatch ever. That record is held by the self-winding Gerald Genta minute repeater movement from sometime in the eighties that was just 2.72 mm high; around the peak of the craze for ultra-thin movements which mimicking the slimness of quartz that started in the seventies. But that thinness came at the price of poor reliability and exceptionally delicate mechanics. Given today’s technology and Richemont’s highly developed industrial processes, I expect this Piaget will work robustly. – SJX
