For decades, Swiss watch- and jewelry-maker Piaget has been at the forefront of ultra-thin movement and watch design. From its storied, hand-wound Calibre 9P from 1957 to the micro-rotor-powered, automatic 12P from 1960, Piaget’s movements have consistently pushed the boundaries of what was possible in mechanical horology.

The modern Altiplano collection is a natural outgrowth of this ultra-thin philosophy. Housing some of the maison’s most compelling timepieces, this line is where Piaget exercises its creative muscles with unbridled restraint, combining ultra-thin watchmaking with avant-garde dial design that causes the entire watch industry to stop and stare.

This Reference G0A39110-P10920 is a case in point. Measuring 38mm in 18K rose gold with a smooth bezel, a signed crown, and a sapphire crystal, its remarkable dial reveals much of the ultra-thin, hand-wound Calibre 900P beating within. With an offset timing dial in anthracite grey and gold occupying the upper left dial quadrant, its remaining real estate is given over to showing off the skeletonized calibre’s balance, gears, jewels, and other componentry. 

At just 3.65mm tall, the dressy 900P is proof positive of Piaget’s command of this type of watchmaking — the type of horological pursuit that seamlessly blends micro-engineering and elegance, yielding a magnificent result. Paired to a brown leather strap, it’s ready to be worn to an elegant dinner party, a business engagement, or every day.
