The story · Since 1983
In 1983 the Italian car designer Giorgetto Giugiaro gave Seiko a family of driver's watches with offset cases and tilted displays. Three years later one of them, the 7A28-7000, was on Ellen Ripley's wrist in Aliens.

Seiko launched its collaboration with Giugiaro Design in 1983 with watches meant to suit the wrists of car and motorcycle drivers. The family, sold as Speed Master, included analogue quartz chronographs on the new 7A28 calibre and digital LCD chronographs whose display tilts toward a driver holding the wheel.
In James Cameron's Aliens, Sigourney Weaver's Ellen Ripley wears the 7A28-7000 and Lance Henriksen's android Bishop wears the 7A28-6000. The watches were not made for the film; both had been on sale since 1983.
Seiko marked thirty years of the partnership with six limited Seiko x Giugiaro Design chronographs in its Spirit range, 40.8 mm quartz pieces shaped like the originals; the red SCED003 echoes the Bishop.
Seiko reissued the Ripley design as the SCED035 in steel and the SCED037 in black hard-coated steel, each limited to 3,000 pieces, with the 7T12 quartz chronograph.
For the 35th anniversary Seiko recreated the digital driver's chronograph as the SBJG001 and SBJG003, 3,000 pieces each, keeping the tilted LCD and the bezel that switches modes. Six store editions of 500 pieces followed.
Film role: as Ellen Ripley in Aliens she wears the Seiko 7A28-7000, which collectors now call the Ripley. No personal ownership is claimed.
Film role: as the android Bishop in Aliens he wears the Seiko 7A28-6000; a screen-used sample piece was later sold by The Prop Gallery.
Reported to have worn the tilted-display Speed Master LCD driving watch before his TAG Heuer association; Grail Watch names the grey/green SSBA022.

The Italian car designer drew Seiko's 1983 Speed Master watches: asymmetric analogue chronographs on the 7A28 calibre, including the 7A28-7000 and 7A28-6000, and digital chronographs with tilted displays. Seiko's museum credits the chronograph's design innovation to him.

An analogue quartz chronograph whose pushers sit at both ends of a block on the right of the case, placed for the right hand while the left grips the steering wheel. Seiko's museum calls its 1983 Speedmaster the world's first analogue quartz chronograph.

No. Seiko describes one of its 1983 Giugiaro chronographs as offsetting the case centre from the band centre for easier use while driving.
The gap between the two lugs that hold the strap, in millimetres. A new strap must match it exactly: 20 mm lugs take a 20 mm strap.
Most watches use spring bars, so any strap of the right width fits. Many smartwatches use their own band system instead, such as Apple Watch bands or Garmin QuickFit.
