Commentary: Asymmetry
Although it is quartz, it is equipped with Cal. 3510 with mechanical-style pushers and was designed as a motorsport chronograph that offers a tactile feel comparable to that of a mechanical watch. To leverage its distinct, positive click for high-precision timing, it featured unusually large S/S pushers for a watch of its time. By rotating the module 30° to place the pusher at the 1 o’clock position, and by enlarging the 1/50-second sub dial as much as possible, it presents an appearance specialized for stopwatch use. The realistic exterior screws and the asymmetric case and bracelet emphasize a sense of speed and tool-like functionality.

Affordance Design

This model is equipped with CITIZEN’s standard chronograph watch layout movement, Cal.3510. While various models featuring Cal.3510 have been released to the market with different design approaches by designers, this particular model stands out as a highly sophisticated design that makes the basic operations of the chronograph immediately clear to users at a glance. The placement of the push buttons and the positions of the hands are designed so that users experience no stress when wearing the watch and using the chronograph functions. To ensure that the complex operations of the chronograph can be understood at a glance and to encourage instinctive and unconscious actions, each push button has a distinctive shape and size. The color scheme of the case, the asymmetrical styling, and every aspect of the design are unlike anything seen before. These distinctive shapes, the mechanical component-like forms incorporated into the outer ring, and the four screws visible on the asymmetric case all serve as details that evoke the impression of a 'chronograph' as a 'precision machine,' completing the model’s design.
