Piaget's ultra-thin Altiplano is a watch for those who appreciate discretion and refined complications. Forget those hulking great big watches that sit on the wrist like a can of tuna and set off security alerts, the smart way to wear a watch is to go for the slimline look, and you can't get any thinner than this classic 43mm Piaget Altiplano in 18ct pink gold. Inside is the revolutionary Manufacture Piaget 1208P mechanical self-winding movement - the thinnest movement in the world at just 2.35mm thick - which has made an icon out of the Altiplano watch. With a purist approach, rather than clutter the dial, this gentlemanly timekeeper limits itself to tracking only hours, minutes and seconds on a discreet subdial. Also the thinnest watch in the world, at a mere 5.25mm, if it's slender perfection you're after, it doesn't get any better than Piaget's Altiplano in 18ct pink gold.
