This black digital watch is part of the sporty G-Squad line of Casio’s iconic G-Shock series, and it comes with a Bluetooth connection. It is an excellent training buddy for both goal-oriented athletes and everyday sporting enthusiasts, and it comes with very versatile training functions, Thanks to the G-Shock Connected app, you can also monitor the results very easily. Unlike common smart watches, G-Shock watches can take a beating, and the battery lasts for years, so it is very good for those who like to stay in the harsh conditions in the badlands for extended periods of time.

The GBD-800 may look robust in pics, but the round shape and weight from the lower end of the series make it very wearable. The design comes from the legendary DW6600 used by the Navy Seals. The 5 mm hole spacing (closer than normal) on the watch enables a better fit on the wrist.

In addition to the precision strap, the watch has a lap/split button on the front and a comprehensive interval timer. If these appeal to you, comparison between models just got easier.

Decoding the name

The cryptic letter/number combination in Casio watch names (GBD-800-1BER) tells you about the watch type and its features. G = G-Shock, B = Bluetooth ja D = Digital.

The number in the middle (800) tells you the watch series. The number in the 1BER suffix is the color code where 1 = black. The letter after that refers to the "order number", B = Second Wave. ER tells that this is the version made for the European market. The various regions are most often just packaged a bit differently, and the manual language varies.
