The Seiko Generation 1 7A28-7120 is a highly sought-after timepiece, often referred to as the Seiko Gen 1 Military Chronograph. It was issued to British military personnel during the 1980s and became famous as the world’s first analogue quartz chronograph.

The Seiko Generation 1 -7120 was officially issued to British forces, particularly RAF pilots and the British Army, from the early 1980s into the 1990s. It gained legendary status due to its precision, durability, and the groundbreaking 7A28 movement, which was the first of its kind.
