Swatch Sistem Chic SUTB402

It wears the 42 mm plastic Sistem51 case, 13.8 mm thick, with stick hands over the numerals. The automatic movement is anchored to a single central screw, gives 90 hours of power reserve and shows through the caseback past a rotor that runs around its edge. It is sealed into the case with structural adhesive, so it cannot be serviced.

The numerals set it apart from plastic siblings with stick-and-dot markers on sunburst dials, such as the silver Sistem Arlequin (SUTW402) and the brown Sistem Fudge (SUTC401), which share the case. The Sistem White (SUTW400) is another white-dial plastic model. For a steel case, the Sistem51 Irony models, such as the Sistem Earth (YIS400), use the same movement.
