To express one of the product concepts, 'a sense of speed,' chamfers that create a slim appearance and edgy profiles are used extensively. The multifaceted case, which looks as if it has been shaved down with a sharp blade, is especially striking and possesses a unique originality unlike any other. Details that could only be achieved through 3D software design are found throughout, and the designer’s individuality is evident even in the smallest details, such as the sub-components that use many corners, slopes, and tapered lines to match the case image, as well as the dial, hands, and fonts. Special attention has been paid to the arrangement of the edges of the ridges and the profile edges. Compared to the case, the metal band has a somewhat more subdued design, but this makes it feel more comfortable on the wrist.

Throughout the model, there is a triangular emphasis on the edges in the arrangement.

By making the bezel thicker and the case body thinner, and by adding steps to the outer edge of the case back, various techniques are used to make the watch appear as thin as possible.

A unique center shape with four flat surfaces.

There are slim and sharp hidden surfaces.

A crown with a tapered shape and four distinctive grooves.

The push button, with its hollowed-out shape and diagonal lines, is thin and gives a very sharp impression.

The indexes are placed on the indicator ring, and by floating the indexes, a sense of depth is created. The fin-shaped outer dial part evokes a sense of speed.

The font uses many diagonal lines, giving it a unique character that matches the case design.

The dial features three-dimensional shapes unique to 3D software, such as twisted surfaces and boundary lines created by steps, giving it a fresh look.

The profile of the hands also features many edges and tapered lines, resulting in a distinctive shape.

The way the printing is applied to the hands is also unique, creating a design that conveys a sleek sense of speed.

Fastest Reception and Hands: the Next Generation
This is the third-generation Satellite Wave, which accelerated reception of satellite radio signals to complete in as little as three seconds—then the world’s fastest at the time—while also achieving a significantly thinner profile to become, at the time, the world’s thinnest radio-controlled watch. In addition, by designing the hour hand, minute hand, and second hand to be driven independently, time-zone correction and the hand movements that reflect the time after reception are performed at high speed, letting you enjoy very speedy and distinctive motions that synergize with the faster reception.
This independent hand-drive mechanism is unusual for a CITIZEN movement, and combined with the difficulty of receiving satellite signals, its development involved considerable challenges; however, the technologies and know-how have been applied to various subsequent models.
This movement also, for the first time, adopts a light-level indicator function that allows you to check the amount of light energy the watch is receiving. Furthermore, it is equipped with a precision-compensation system of ±5 seconds per month, making it a bold movement/model that incorporates numerous new initiatives as an Eco-Drive.
