Introduced in 1979, the Piaget Polo quickly made its mark as the brand’s sport-luxe watch. Not only does this 42mm version fit that bill perfectly; it does so with the additional constraints of a wafter-thin, skeletonised movement, areas in which Piaget has excelled since the 1950s. All the design traits of a Polo are there, not least the curved steel case surmounted by a round bezel framing a cushion-shaped dial. Blue PVD treatment on the plate and arabesque bridges of the superbly skeletonised movement accentuate the watch’s sporting character, as does 30-metre water-resistance. The movement in question, Calibre 1200S, keeps all its promises in a height of just 2.4mm, inside an equally slender 6.5-mm high case that slips effortlessly under the cuff.
