Arguably known for being the first watch on the Moon, Omega’s Speedmaster collection has seen many variations. The tachymeter scale on the Speedmaster bezel was the first of its kind. Today, the tachymeter bezel is still a staple on the Speedmaster; it is used to measure the speed at which the wearer travels over a fixed period of time.
