Casio’s new calculator watch features design details inspired by Back to the Future’s DeLorean. | Image: CasioIt 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.Michael J. Fox’s character actually wears a Casio CA-53W in those films with a plastic strap and case, but Casio’s new CA-500WEBF-1A is based on a later model that swapped plastic for metal. The watch’s functionality remains the same — including an 8-digit calculator, time and date capabilities, a stopwatch, and daily and hourly alarms — but it now incorporates design elements from Back to the Future’s time-traveling DeLorean. The watch’s keypad features labels inspired by the vehicle’s time circuits, while on the back you’ll find an engraving of the flux capacitor.The Casio CA-500WEBF-1A will be available for preorder starting on October 21st, 2025, according to Hypebeast, and is currently listed on the company’s website for $120. It will come in packaging that looks like a VHS copy of the original movie, but there’s nothing to actually wind or rewind.
