The watch was conceived by Italian car designer Giorgetto Giugiaro in the early 1980s, and is known for its blocky panel that houses chunky chronograph buttons to the right of the watch face.

The Seiko 7a28 series are the world’s first watches to use an analog quartz chronograph movement. The 7A28-7000 was worn by actress Sigourney Weaver who plays the role of former warrant officer and alien attack survivor Ellen Ripley in the best action-horror movie ever made James Cameron’s 1986 “Aliens”.

Note: Seiko 7A28-7009 is another Sports 100 watch, similar to the  7000 version above, but with red pushers. Its futuristic design is reminiscent of the popular “Aliens” watches. It features orange hands, stick hour indicators, and sub dials at the 3, 6, and 9 o’clock marks. Markings on the dial include “SEIKO,” “QUARTZ,” cursive “Chronograph”  and “SPORTS 100.”
