Oris 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 fibre 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. The ProPilot Altimeter's case is produced using a unique "additive manufacturing and moulding" process developed by our Swiss partner 9T Labs. This is different to normal 3D-printing, which is mainly for prototyping. We can industrialise manufacturing and use the technology to produce structural end-use parts at high volumes. This is a real breakthrough.
