Take a step back to 1983 with a timepiece that pays respect to the world’s thinnest calculator in its time, the Casio SL-800.

A revolutionary calculator no bigger than a credit card , the eight-digit SL-800 paved the way for much more to come.

Casio revives this iconic design in timepiece form, bringing the original ’80s touch to the ever-popular A168 — by using the retro black and gold base colors of the SL-800, and even the same accent colors used for the time display numbers and other details.

Vintage flair meets contemporary style for a timepiece as eye-catching as it is nostalgic.

SL-800
At 85 mm x 54 mm, the eight-digit SL-800 calculator was astonishingly slim, at just 0.8 mm, and light, at 12 g. The calculator represented the pinnacle of the digital technologies that made possible a new era of slim, lightweight, compact products. It also laid the foundation for Casio development of state-of-the-art high-density mounting technology. In 2013, the SL-800 was designated an Essential Historical Materials for Science and Technology (or Future Technology Heritage) by the National Museum of Nature and Science in Tokyo, as a calculator with an extraordinarily slim, compact form.
