Because it does not have the need to change out batteries, the Casio Pro Trek watch is totally environmentally friendly. A compass comes standard on the watch. These features, plus its overall durable and well-built nature, make it perfect for those who spend a lot of time outdoors. It also features a stopwatch, which makes it excellent for those who are sporty to keep up with their best times. All the information is displayed in a digital format on the Casio watch to make it legible and readily accessible at any time.
