The Casio CA-500WEBF-1A pairs the familiar calculator-watch format with Back to the Future details inspired by the DeLorean and its time circuits. It is a 40th-anniversary collaboration, not an established screen-used replica, and its practical features include an 8-digit calculator, stopwatch, alarm and dual time.
Casio CA-500WEBF-1A: what it is
Casio identifies the CA-500WEBF-1A as a Casio Vintage and Back to the Future collaboration based on the CA-500 calculator-watch design. The release marks the film’s 40th anniversary. The European model is designated CA-500WEBF-1AER; check the model shown on your regional Casio page.
The CA-500WEBF-1A is not established as the exact watch worn by Marty McFly in the film. It is a licensed design inspired by Back to the Future and the DeLorean, rather than a confirmed screen-accurate prop replica.
A DeLorean-inspired face with time-circuit details
The appeal is in the details Casio has added to its recognizable calculator-watch layout. Casio says the colored areas around the buttons evoke the DeLorean’s time circuits. The international product page also highlights a DeLorean-inspired design, a Flux Capacitor engraving on the caseback, a Back to the Future logo on the buckle and special packaging featuring scenes from the film.

What to check before buying
- Confirm the model designation for your market: CA-500WEBF-1A or the regional designation shown by Casio, such as CA-500WEBF-1AER in Europe.
- Check the regional Casio listing or an authorized seller for current stock and price; neither is established by a historical announcement.
- Ask whether the special packaging is included if completeness matters to you.
- Treat claims that it is Marty McFly’s exact screen-used watch, or that a specific number were made, as unverified by the reviewed material.
- Do not infer swimming or diving suitability from the general “water resistant” description alone.
Verdict
The CA-500WEBF-1A makes its Back to the Future connection through concrete design touches: time-circuit-inspired colors, a Flux Capacitor caseback, branded buckle and film-themed packaging. It keeps the useful calculator-watch format, too, with an 8-digit calculator and everyday digital functions.
