About the brand

About the brand Casio


Casio, Japan is one of the best-selling watch brands in the world. The first watches from the Casia workshop were digital and at the same time the first in the world to display the date. Casio's digital watches are no longer popular today, although analog watches or watches with a combined time display already form a large part of the range.

Casio has made history with its range of super-durable G-Shock watches, which are equipped with a light but sufficiently durable construction (against falls of up to 10 m, shocks, vibrations, magnetic field and temperature fluctuations) and a great value for money. The glory of the G-Shock watch over time also required a lightweight women's version - Baby-G. The Casio Pro Trek or Casio Edifice outdoor watches are also very popular. Casio does not lag behind in modern technology either, as evidenced by models equipped with Bluetooth technology, the Tough Solar solar drive or the high-precision radio-controlled Wave Ceptor watch.

Model lines: G-Shock - Wave Ceptor - Edifion - Classic Collection - Pro Trek is an authorized dealer and specialist of the Casio brand.
