This is the Chronofighter Oversize Black Arrow (in Celsius), and here are the details straight from the source -

Dedicated to action and courage, the Chronofighter Oversize Black Arrow watches, present distinctive military style fatigues on a silkscreen printed dial. Each dial is engraved with a unique identification number on the seconds counter, based on regimental numbers.

The start and stop lever on the left of the case, the renowned GRAHAM signature, is made of plain carbon material and results from a very specific machining process. This means that the lever is a unique piece of carbon which provides the watch with more stiffness and enhanced usability.

To brave the elements, each watch is endowed with a calculated telemeter scale. It enables to measure distances thanks to the speed of sound by starting the chronograph when a visible event occurs (e.g. lightning, explosion) and stop it when the sound reaches the observer (e.g. thunder, deflagration). As the temperature influences the speed of sound, our engineers have based their calculations on 25°C, the average temperature on Earth. The distance in kilometres can be measured on the dial thanks to the scale rim (346 m/s).
