The perfect alchemy

Philippe Leopold-Metzger, Piaget chief executive

What was the first watch you owned? A Universal Geneve. A very flat, round watch.

Which is your favourite aspect of watch craftsmanship? I love the encasing operation, just when the watchmaker puts the movement in the case, and creates the perfect alchemy between the art of the watchmaker and the art of the jeweller.

What is your favourite time of day? The early morning, when I open the window, breathe fresh air, and wind up my mechanical Emperador tourbillon watch. I always feel that the world belongs to me.
