Sorry Hammy but yet again I feel the need to point something out to you.
I have it on very good authority the SAS ... yes the SAS ... use these watches on special ops. Under cover of darkness, they signal to each other using morse code by flicking their wrist back and forwards. Assuming no obstacles, they can do this from a distance of 5 miles from each other. and even then, because of the brightness, they need to wear special night time goggles to reduce the glare.
I shouldn't really be saying this but the SAS and our other armed services use quite a lot of IW / Shop Extra products in their defence and attack kit. Whizzy whisk for close up combat. Weighted blankets to stop the enemy on their tracks. Drones for reconnaissance. Collectibles to bribe the enemy if our troops find themselves captured. Air fryers (using battery power from the drones) to cook food when in the field. Electric bikes to quickly get from a to b over all types of terrain.
The list goes on ... ALL procured from IW / Shop Extra.
