1. A. Lange & Sohne Perpetual Calendar Terraluna
The large 45.5mm diameter face fits three dials - the large minute dial dominates at the top, whilst the bottom right dial counts hours and the bottom left counts seconds. More impressively the small windows at 3 and 6 on the face display the day and month of the year thanks to the perpetual calendar motion, and there’s a beautiful moon phase display on the back too.

2. Piaget Altiplano 900P
Swiss watchmaker Piaget has been making ultra-thin watches since way back in 1957, but the Altiplano 900P is the thinnest of them all. Its 3.65mm thick, and still has room for 145 parts inside it - an incredible piece of engineering that puts Piaget on top once again.
Price: $20,000 | Piaget
3. Richard Mille RM63-01 Dizzy Hands
Richard Mille has built a reputation for pushing the boundaries of watchmaking, both technically and aesthetically. Dizzy Hands is in effect, a concept piece, based on a poem called ‘Le Temps’ by 19th century French poet Gérard de Nerval. Pressing down the centre of the crown causes the dial to rotate counter-clockwise… press it again, and the time will reset, accurate to the millisecond.
