INTRODUCING: The ProPilot Altimeter.  Meet the new ProPilot Altimeter, the world’s only watch to combine a mechanical altimeter with an automatic mechanical movement.

The second generation piece is better than ever: higher, slimmer, lighter.

Higher: because thanks to a new pressure box, it can now gauge altitude up to 6,000 metres or 19,700 feet, depending on which model you go for.

Slimmer: because we’ve upgraded the movement to the thinner Calibre 793, which also has a bigger 56-hour power reserve. The watch is 1mm thinner than the previous generation.

And lighter: because its case is made of a pioneering carbon fiber and PEKK composite we’ve brought into watchmaking for the first time. The new watch weighs just 98 grammes, a drop of 70 on the outgoing model.
