It wasn't the first watchmaker to release a wristworn calculator, but by making them affordable, Casio's calculator watches became an icon of '80s technology. It was even the timepiece of choice for Back to the Future's Marty McFly, and as 2025 marks the 40th anniversary of that film's release, Casio is once again resurrecting one of its most popular calculator watch models and giving it a time machine makeover.
The G-Shock MRG-B5000HT features a gorgeous 'tsuiki' or hammered texture on its bezel and body. Meticulously forged by a single Japanese master artisan, each watch brings that true handmade finish to life.
