1983 Seiko Chronograph Sports 100
(ref. 7A28-7009)

This Rare Seiko was designed by Influential Car designer Giorgio Giugiaro and is often referred to as the “Alien” because the character Lieutenant Ripley (played by actress Sigourney Weaver) wore a silver colored version of this watch in the 1986 movie Aliens.

The Watch houses Seiko's First Ever Quartz Analog Chronograph movement - The 7A28, which was recently serviced July 2023. It keeps good time and all chrono functions operate as they should.
