Introducing: Piaget Updates Their Classic Polo With An Ultra-Thin Perpetual Calendar
But of course, all those watches are hand-wound, and much of what makes a watch thicker is its self-winding mechanism, and obviously its complications. So, this is Piaget’s first Ultrathin Perpetual Calendar. This watch is 42 mm and 8.65 mm thick. It comes in green only, with a horizontal textured groove that calls back on the Polo’s early godroon styling. The month, day, and day of the week are in titanium edges subdials at 12, three, and nine. The moonphase is at six, and the power reserve is 42 hours.
