Casio recreates the 1974 classic but with a few modern updates and features

Casio Computer Co., Ltd. has released a new watch re-creating the Casiotron QW02, the world’s first line of digital watches with an automatic calendar function, to commemorate the 50^th anniversary of Casio watches. The new TRN-50 is available in a limited edition of 4,000 watches worldwide.

Going Back

Casio originally released the Casiotron in 1974, breaking ground with a digital wristwatch inspired by the insight that “watches simply add up seconds.” The watch made the most of the original digital technologies Casio had developed in its calculator business, bringing the concept of a fully automatic wristwatch to life.

The Casiotron not only displayed time but also the correct month, date and day of the week, automatically adjusting for longer and shorter months with its automatic calendar function. Eliminating the hassle of correcting the calendar every month, the Casiotron was a true pioneer that went beyond what anyone expected of a digital wristwatch.

True To The Original

The new TRN-50 stays true to the Casiotron concept of a fully automatic wristwatch, drawing on all the advancements of Casio watch development over the half-century since the original model came out.

While re-creating the Casiotron design, the new watch incorporates state-of-the-art features including radio controlled time adjustment, solar charging, and Mobile Link functions for pairing with a smartphone.

Small Details, Big Impact

The original watch exterior, including its size, is meticulously re-created in a design that meets present-day quality standards. Many details, including the sophisticated textures of the case and band, the dark blue face, and the CASIOTRON logo, are faithfully reproduced.

The new watch also delivers practicality with the highly readable super-twisted nematic (STN) LCD and Tough Solar charging system. In addition to receiving time calibration signals transmitted from six stations around the world, the watch is equipped with Mobile Link functionality for pairing with a smartphone via Bluetooth to ensure precision timekeeping.

Special details befitting a limited-edition timepiece include the original case back design with engraved serial number and special packaging made from paper materials for low environmental impact.
