TRN-50SS-2A

Celebrate 50 years of Casio watches with a beautifully updated Casiotron that symbolises Casio's determination to stay true to who we are, while constantly innovating.

This special limited-edition re-creation features a special commemorative colour scheme and design with Casio colours, materials, and finishes that evoke the omnipresent yet ever-changing nature of the sky, the sea, and the sunlight — shining today and forevermore.

The iconic fluted pattern of the original Casiotron, logo, buttons, and other details are accented in a gold hue inspired by the look of brilliant sunshine. Paired with a dark blue hue evoking the sky and sea, the design is a study in beautiful contrast. 

Glass with blue-toned printing adorns the stainless-steel screw-lock case back, which also features the 50th anniversary logo in a gold hue. A gold-and-silver bicolour finish is applied to the tri-fold clasp that, when opened or closed, reveals an engraved triangle pattern and "50th Anniversary" lettering in the golden folded section.

This very special 50th anniversary-worthy Casiotron is packaged plastic-free in a paper box, in keeping with the Casio commitment to the environment.
