The result was a repeater that sounds at an impressive 64 decibels, striking in the 5th octave. The hours are pitched to G sharp, and the minutes at A sharp. This is accomplished by using steel hammers, activated by the traditional slide at 9 o’clock. It also uses an inertia fly-wheel to regulate the rhythm between the start and finish of the chiming.

Calibre 1290P also houses the most prestigious level of finishing ever performed by Piaget: the “image finishing” level. Featuring alternating interior and exterior angles. Bridges hand-bevelled and hand- drawn with a file, sunburst or circular satin-brushed wheels, pink gold-toned screws and oscillating weight, mirror-polished finishing – the hand-finishing takes a mind-blowing 70 hours.

The 48mm rose gold PIaget Emperador Coussin Ultra-Thin Minute Repeater is an incredibly impressive piece of technical watchmaking, and while we have no word on pricing or availability, you can be sure we’ll do our best to go hands-on with this guy at SIHH, and hopefully get a video of it in action.
