Skillfully utilizing the constraints of the movement's shape, the design is simple yet dynamic. With excellent operability and visibility, it is a masterpiece that can be called the bible of CITIZEN diver's watches. The polyurethane band is printed with "N.D.LIMITS (No Decompression Limits)", indicating the no-decompression limit values.
The design maximally emphasizes the water pressure sensor, which is the main feature of this movement, giving it a powerful and distinctive look. The overall case shape is streamlined with no waste. The functions are embodied in the form, giving a sense of decisiveness.
The side surface of the bezel features a knurled cut, making it easy to turn even when wearing gloves.
When worn on the left wrist, the design of the sensor at the 9 o'clock position is thick and wide, giving a sense of power without interfering with the wrist. There is also a sense of security as the delicate pressure sensor is protected.
The aluminum nameplate on the inner side of the bezel is slanted in reverse, so when the watch is placed upside down, the glass does not touch the surface directly.
Although the shape of the case back is determined by the shape of the movement, the outer shape is impressive. The six screws serve as an accent.
The side surface of the crown, like the bezel, features a knurled cut, making it easy to turn even when wearing gloves.
The LCD display that shows diving-related information is positioned at 12 o'clock, giving the dial a distinctive look. The indexes and hands are mostly composed of straight lines, giving an overall sharp impression.
For the 1 o'clock and 11 o'clock indexes, whose area is reduced by the LCD display, the cutout windows are precisely set at 30°, making the hour easily readable.
Hour hand: Although it is a thick hand typical of a diver's watch, the fence in the center makes it easy to see the indicated position. Minute hand: The top surface is printed in orange to differentiate it from the hour hand, enhancing the visibility of elapsed dive time.
