Omega milestone museum collection, limited edition, 18k white gold, telemeter. Originally issued to military generals. The scaling on the dial is to calculate how far the enemy was, so they could set their artillery to the right angle. When they saw the fire of the enemy’s artillery, they would start the chronograph, and when they heard the sound they would stop it, and whatever number the chronograph hand pointed at, was the distance between them and the enemy!
