Celebrating 50 years of Casio watches:
A limited-edition re-creation of
the Casiotron
We bring back a historic Casio design using today’s technologies by re-creating the Casiotron — the very first wristwatch Casio released in 1974 — to commemorate the 50th anniversary of Casio watches. The Casiotron was the first digital watch in the world with an automatic calendar function. We reproduced the original design meticulously, including its size, while meeting present-day quality standards. This special model symbolises a half-century of commitment to originality and innovation. Available in a limited edition of 4,000 pieces worldwide.
With its debut in 1974, the Casiotron — the very first wristwatch Casio ever released — eliminated the need for monthly calendar correction with its automatic calendar feature. This embodied our philosophy and commitment to contributing to society by offering products with innovative functionality that has never been seen before.
The new TRN-50 perpetuates the spirit of the original Casiotron with its incorporation of updated modern technologies. In addition to receiving time calibration signals transmitted from six stations around the world, it is equipped with Mobile Link functionality for pairing with a smartphone via Bluetooth® to ensure precision timekeeping. Features including automatic updating of world time zone/time difference information via smartphone pairing deliver practicality and convenience as well.
World’s first digital watch with an automatic calendar function
Casiotron(QW02)
Hitting the scene in 1974 as the very first wristwatch Casio ever released, the Casiotron eliminated the need for monthly calendar correction with its automatic calendar feature. With a conventional watch, people had to reset the calendar date on the first of each month, but the QW02 eliminated this hassle. Later, Casio delivered a fully automatic calendar watch that even correctly displayed February 29 during leap years. Casiotron: a name to be remembered as the point of origin for a half-century of commitment to the ongoing evolution of digital technologies.
Re-created design commemorates the Casiotron 50th anniversary
A close look at the design of this watch from 50 years in the past reveals careful consideration of factors including ease of the time’s readability and textural appeal. Separate finishes are applied to the surfaces of the case and band, and the dial and grooved panel cover are crafted with luxe quality. Now, as then, the wristwatch continues to function as a practical device as well as an accessory adding fashion flair. The original design is meticulously reproduced with a dark blue dial, Casiotron logo, and many other details.
Special case back design
Just like the original, the new TRN-50 features a screw-lock case back. The centre of the case back employs glass to allow for radio wave reception with the built-in antenna. The symbol featured on the original case back has been redesigned to commemorate the 50th anniversary and is accompanied by engraved serial numbers (0001/4000–4000/4000) to highlight the rarity of this special limited edition.
*The orientation of the case back may vary from watch to watch due to details of the manufacturing process.
*Graphics are included for illustrative purposes and may vary from actual appearances.
Capping a 50-year history of originality and innovation with new functional evolution
A half-century has passed since the debut of the world’s first digital watch with an automatic calendar function. This re-creation of the Casiotron faithfully reproduces the original design, while incorporating the advanced technologies of today, expressing our commitment to staying true to origins and constantly innovating. The use of smaller components and high-density mounting technology enabled us to build in Smartphone Link, radio wave reception, and the Tough Solar charging system, all while maintaining the size of the original watch.
Special packaging for a limited-edition commemorative model
As part of our ongoing effort to utilise the world’s limited resources effectively, Casio has done a major re-evaluation of the packaging for its Casio Collection of standard watches. By adopting paper as the primary raw material, we achieved an approximately 82% reduction of plastic usage compared to the conventional packaging. The box for this special model is also made with eco-friendly, plastic-free paper material.
