Equipped with an impressive range of tech features intended to support land missions, all sensors can be linked to a dedicated app for data capture and mission monitoring. The watch has a triple sensor and an accelerometer: the three sensors detect compass bearing, measure atmospheric pressure/altitude, and gauge temperature, while the accelerometer counts steps. Countdown start time setting range: 1 second to 24 hours (1-minute increments and 1-hour increments) The carbon fiber bezel is made with a carbon fiber sheet inserted into the fine resin. The top fine resin layer is transparent which allows the the carbon fiber to be visible. time zones (38 cities + coordinated universal time), daylight saving on/off, Home city/World time city swapping Barometric pressure tendency information alarm (beep and arrow indicates significant changes in pressure)

When you press the top right button you get the seconds hand now pointing north for you AND a digital readout in bearing degrees for the direction you are currently facing. You can also change this readout to a NSEW readout rather than a specific bearing. The watch also allows you to drop a virtual pin on a location and then have the watch indicate direction for you to return to that location later. Battery

A built-in pressure sensor measures barometric pressure, which is converted to relative altitude, Altitude Graph: Changes in altitude are represented by a graph on the watch face, Measuring range: -700 to 10,000m (-2,300 to 32,800ft), Measuring unit: 1 metre (or 5ft) Sunrise and Sunset times are displayed for your chosen location.
