For an analog clock that displays time with a circular motion of the hands, the casing trim being round is the both the most natural and the most basic shape. A round shape, which for a clock is a stable one, is the most standard shape and makes it naturally easier for people to see and read. Although an undistorted round frame, possible only with something that is aluminum die-cast, is in comparison a little heavier than a plastic one, it has a high quality feel to it. A slight R on the upper face of the frame and a slight spreading outward give a not too sharp, rather soft feeling to the whole. Having pursued visibility, raised printed bar markers were used instead of Arabic numerals. Though people are inclined to think “large letters = easy to read” and “numerals = easy to read,” what is important is that the letters and numbers are well-balanced and that they naturally catch the eye. Volume has been added to the round portion at the base of the hands at the center of the clock, so that the center is the initial focus when the clock is looked at; the time can be checked in an instant. Three sizes, large, medium and small were developed so that this clock comfortably fits into a range of different rooms.
