To Be Kind

An all-analog diver's watch equipped with a depth gauge. By making the approachable feel and excellent legibility of analog the key point and trimming away unnecessary functions as much as possible, it thoroughly pursues ease of use to enhance benefits. Cal. B740 simultaneously displays the time and depth—both essential for diving—by means of hands. A depth hand is arranged coaxially with the hour and minute hands, so you can easily read the current depth by the angle of the hands with the same familiar watch sense. Specifically, since each minute track corresponds to 1 meter, you can know the depth by which “minute” the depth hand indicates, allowing you to see at a glance how many meters you can descend. This is effective even in the dark thanks to luminescent hands. There are broadly two types of register rings. One places a knurled cut around the entire circumference so you turn it by catching your finger with friction. The other places about six large blocks that you grasp to turn. This model is the former, and because it has a volcano-like shape, even the pad of your finger catches, making it very easy to turn. Regarding the back shape of the case, the protrusion beneath the sensor is covered with a gentle curved surface for a unified finish. The composition of complex three-dimensional curves also sits very comfortably on the wrist, conveying a sense of kindness.

Medical Motif

A model approached with a design concept inspired by a clean and transparent medical motif. The organic styling gives it a strong sense of individuality. Translucent textures, which were a trend at the end of the 20th century, are used for the case, band, and other parts. Light is also brought in from the side surface of the three-dimensional crystal, and new ideas are incorporated, such as indexes designed to resemble transparent capsules. In addition, the asymmetrical case between 12 and 6 o'clock causes the dial to tilt slightly toward the wearer when worn, making it easier to read the time.

Early Adopter Gadgets

This model is a watch that uses the Bluetooth® hands-free function found in mobile phones to notify you of incoming calls via vibration and light. The design, aimed at early adopters, features a gadget-inspired aesthetic with details such as a hairline-finished main plate, hex screws, and polyurethane parts reminiscent of the punched metal of speakers, all brought together with a precise, slightly retro shortwave radio feel. Through the upper window, you can see the vibrator motor. When this motor rotates, an LED light shines on it, diffusing the light to notify you of incoming calls. The design aims to provide both tactile (vibration) and visual effects. To enhance the gadget feel, the motor is intentionally made visible. Due to the thickness of the case, the back is shaped as much as possible with curves, utilizing the characteristics of plastic molding to improve the fit on the wrist. Additionally, a new structure was devised that combines a polyurethane band with an internal side push button and a free-adjust clasp, making it easy to put on, take off, and adjust.
