Celebrate 50 years of Casio watches with a commemorative Casiotron timepiece that sparkles with Casio passion for new value and constant innovation.

The Casiotron TRN50ZE embodies the spirit of craftsmanship inspired by the excitement of “making something from nothing” — the thrill of going from “0” to “1” — the total creativity that brought the world the very first Casiotron in 1974. The first wristwatch released by Casio, the Casiotron was also the world’s first digital watch with an automatic calendar function.

The 50th anniversary TRN50ZE pays homage to the original, but with a black and gold colour scheme that evokes the first flicker of light, that spark of innovative craftsmanship, where the creation of new value begins.

The gold colour of the bezel, logos, and other elements complements the sophisticated look of the dial and dial ring for a luxe design that makes it easy to read the time.

Separate hairline and mirror finishes on the stainless-steel band add sophisticated textural appeal. The single gold-colour link on an otherwise black ion-plated band is a special touch that catches the eye, flickering like a light that breaks the darkness and illuminates the path to value innovation. The link is also laser engraved with “50th ANNIVERSARY.”

The case back*1 employs special design features worthy of a limited-edition anniversary model. These include an engraved “CASIO 50th ANNIVERSARY” mark encircled by 0’s and 1’s, capturing the Casio devotion to the art of making something from nothing.

The watch comes in special environmentally responsible packaging made with recycled materials, including a cotton pouch for storing accessories.

*1 The orientation of the case back may vary from watch to watch due to details of the manufacturing process.

Note: Graphics may vary from actual appearance.

Commemorative timepieces sparkling with the Casio passion for new value and constant innovation

A spirit of craftsmanship expressing the journey: “Making something from nothing”

The first wristwatch Casio released in 1974 — the Casiotron — was the world’s first digital watch with an automatic calendar function. Over the half-century since, Casio has taken on many other challenges, always remaining committed to originality and constant innovation. With a devotion to craftsmanship inspired by the thrill of “making something from nothing” — Casio has driven the evolution of the timepiece by introducing ever-expanding functionality.

Commemorating the Casio Watch 50th Anniversary, the Casiotron TRN-50ZE features a black and gold colour scheme that evokes the first flicker of light, where the creation of new value begins.

Design motif evoking the first flicker of light, where the creation of new value begins

The gold color used for the bezel, logos, and other elements, combined with the sophisticated look of the dial and dial ring, creates design that makes it easy to read the time and delivers a luxe textural appeal.

Stainless-steel band with two-tone finishing

Separate hairline and mirror finishes give the stainless-steel band a sophisticated textural appeal. As a special design touch, a single gold-color link stands out on the otherwise black ion-plated band, evoking the first flicker of light that ends the darkness. The link is also laser engraved with “50th ANNIVERSARY.”
