Casiotron 50th Anniversary TRN50ZE-1A

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.
