PIAGET Exceptional Pieces Collection – Ref: G0A37020 (Emperador Perpetual Calendar Gem Set Cushion-Shaped Watch – 49 mm)

From the workshop of Georges-Edouard Piaget, created in La Côte-aux-Fées in 1874, to the international-scale luxury brand it has now become, Piaget has succeeded within almost a century and half in developing an exceptional two-fold watchmaking and jewellery expertise. Located in two sites – La Côte-aux-Fées in the Neuchâtel Jura region and in Plan-les-Ouates near Geneva – both of which have made a speciality of one of these skills, Piaget presents exclusive models that transcend the constraints of time.

This technical virtuosity is brilliantly highlighted in the Emperador Perpetual Calendar model which houses the 856P Manufacture Piaget ultra-thin movement, combining a perpetual calendar and a dual time-zone with retrograde date and day displays, with classic displays of the months and leap-years. The indications appear on a particularly elegant black mother-of-pearl dial.

The case (including the profiles), the hour-markers, the rim of the sapphire crystal case-back, the buckle and even the oscillating weight that may be admired through the transparent case-back, are all lavishly set with baguette- and brilliant-cut diamonds. The admirably elegant case and sides are enhanced by ideally calibrated baguette-cut diamonds beautifully moulding the cushion shape of the case. Over 100 hours of gem-setting were required to craft this numbered model studded with 560 brilliant- and baguette-cut diamonds totalling approximately 15.3 carats.
