W-100
This watch had the rigid resin case, but with 100-meter water resistance. Its comfortable fit and lightweight design made it great for swimming and other water sports, and it also had a stopwatch, timer, and other functions useful for athletes. Even powering all this functionality, the battery life was still great, at about five years.
C-80
This wristwatch incorporated a keypad the user could operate with a fingertip, leveraging original Casio miniaturization technology. In addition to doing all you would want in a watch, it offered all four arithmetic operations to eight digits. Even further, the Finger Touch System (FTS) circuitry could electronically determine the likely intended key when the user pressed two or more at once. Reinterpreting accidental input to grasp what the user meant to do — this was a truly conscientious design touch of the sort only Casio, a calculator maker, would think of. This timepiece was a milestone in both multifunctional watch development and wearable calculator design.
J-100
This sports-oriented timepiece was created just in time for the worldwide jogging boom. Helping joggers keep their desired cadence with an electronic signal, the watch could also measure required time, distance, number of steps/strides, and average speed if the user specified stride length. It also displayed lap times down to 1/100 of a second. Rigid resin was used to allow for a lightweight, colorful design. From athletic-minded younger fans to health-conscious older users, joggers of all ages loved this watch.
T-1500, T-2000
Casio leveraged original LSI technology to develop a CPU capable of running English-Japanese and Japanese-English dictionaries on these digital watches. The T-1500 included English terms and phrases at about the level of a junior high school graduate, while the T-2000 went further with terms and expressions for travelers and businesspeople. Needless to say, all the desired basic watch functions were included, as well. Another new step for Casio — a “walking dictionary” that changed the time-telling wristwatch into a wearable information device.
DW-1000
Designed to perform as a diver’s watch, this was the first Casio digital watch to deliver 200-meter water resistance. The stainless-steel, screw-lock case back ensured a water-tight seal. Paired with a top bezel made of resin, this made for an all-around heavy-duty design. Even when using the stopwatch or timer functions, the watch also separately displayed the current time, a highly practical feature. More than ready for intensive use, it also had long-term stamina, with a battery life of around seven years.
TS-1000
The TS-1000 could tell the temperature, another first for a wristwatch. It employed a fine ceramic semiconductor called a thermistor to sense changes in temperature. The alarm function even notified users of temperatures above or below specified ranges. Despite the greater number of components, the watch was still an easy size to wear, thanks to the new single-chip microprocessor and high-density mounting technology. This also ensured low power consumption, providing for a roughly three-year battery life.
AQ-500 (Janus)
Offering both a digital display and an analog display complete with hour, minute, and seconds hands, this watch gave the advantages of both: an intuitive grasp of the time at a glance and confirmation of the time with precision.
