The Family: Classic Collection

The Casio Classic Collection includes some the most iconic watches the company has ever made. Popular today due to their retro appeal, refreshingly simple practicality, and understated styling, the Casio Classic Collection of timepieces are truly timeless and appeal to an almost uniquely broad range of people; proof that some things genuinely never go out of style.

The Brand: Casio

Casio was established in 1946 by Japanese engineer Tadao Kashio. The company entered the watch market in 1974 with the release of the Casiotron, which was the world’s first Auto Calendar watch. Only eleven years after entering this field Casio reshaped global thought about the functions a watch should perform, this began with the release of the pioneering and the now legendary G-Shock family.

Innovation and world firsts have defined the company’s history ever since. The most striking of these being the release of the first ever touch screen watch in 1991, 24 years before the Apple Watch. Also, the first ever wrist camera watch in 2000. Casio have been producing smartwatches decades before the term ever came into circulation. Casio has firmly cemented its reputation as a famously reliable and precise name in both analogue and digital watches.
