Good luck wearing a watch this thin, the crystal is only 0.2mm thick. Any slight flex in the case putting it on or taking it off will put that crystal under great stress, and if you put any impact on it while on your wrist, goodbye crystal. Some years ago Concord had their Delirium series that got thinner and thinner, eventually reaching <1.5mm, but they were unwearable, the crystal would pop off by putting stress on the case as the strap was tensioned. This Piaget is a great achievement for sure, but it isn't a real practical watch in day to day life.
