Oris X Bamford Watch Department Propilot Altimeter ‘Mission Control’Beyond boundaries Lighter than titanium, stronger than steelThe carbon-fibre composite case of the ProPilot Altimeter Mission Control delivers exceptional strength and lightness.The ProPilot Altimeter Mission Control is the only watch in the world (or space) with an automatic mechanical movement and a mechanical altimeter. It has a carbon-fibre composite case and an altitude scale in feeHow it worksThe ProPilot Altimeter Mission Control can measure air pressure and gauge altitude up to 19,700 feet. Its also designed to be simple to operate and use1. Neutral mode(Crown position 0) In neutral mode, when its crowns are screwed in, the ProPilot Altimeter Mission Control is a regular automatic watch. Time is displayed by the hands on the central dial (adjusted by the crown at 2 oclock), and the watch is water-resistant to 10 bar (100 m).2. Activating the altimeter(Crown position 1) To activate the altimeter, unscrew the crown at 4 oclock into position 1. At that point, a red ring appears, indicating the altimeter is in use.3. Setting the altimeter(Crown position 2) To set the altimeter, pull the crown out to position 2 and rotate it so that the reference air pressure (supplied by an airport control tower, for example) aligns with the red triangle at 6 oclock on the central dial. The watch now shows the current altitude, shown by the yellow indicator, and the current absolute air pressure, shown by the red indicator. While activated, a patented Oris altimeter-adjustment and venting crown, equipped with a PTFE vapour barrier, stops ambient moisture entering the watch.4. Measuring altitude(Crown position 1) Having set the altimeter, push the crown back into position 1. Changes in altitude are shown by the yellow indicator against the outer dial ring, on a scale from 0-19,700 feet. The altimeter hand is made from lightweight laminated carbon fibre. To deactivate the altimeter and return it to neutral, screw the crown back into position 0. This also reseals the watch so that it becomes water-resistant to 10 bar (100 m).
