The Casio G-Shock Tough Solar Aviation Watch GW-2500-1AER is part of the G-Shock aviation series and is especially designed for ease of use under cockpit conditions subject to strong gravitational forces.

The dial of the watch can be read instantly and the large buttons offer reliable operation of the stopwatch and other functions. The face is matte black to minimise the reflection of bright light at high altitude.

The large arabic numerals at the 12 and 6 o'clock positions combine with sharply pointed hands and luminous material is used at strategic positions on the dial for easy reading in dark conditions.

The G-2500 also features Tough Solar power energy and boasts Multiband 6 radio-frequency control timekeeping accuracy.
