The Timex Expedition WS4 is a great ABC (Altimeter, Barometer, Compass) watch at a great price. It is affordable and sets new standards for ease of use; the watch is much easier to use than my Casio Pathfinder and the sensors are more precise and accurate.
Calibrating the WS4, a sometimes tricky task with competing products, is straightforward and exceptionally flexible. For instance, multiple calibration points for the altimeter can be entered into the watch so that the watch can be instantaneously calibrated when you are at a set location.
The large display is very readable and provides an unmatched amount of information. The Indiglow backlight is very bright and illuminates only the LCD digits and pixels.
The chronograph records up to 99 laps while also logging sensor information which can later be reviewed. The timer can be set to immediately restart while reporting the number of times it has restarted.
While the watch is large, it is light and comfortable. The watch looks surprisingly good. I was afraid the camo design would be over-the-top, but it actually looks great.
The Timex Expedition WS4 is a handsome, approachable, thoughtful, full featured, easy to use ABC watch at a very fair price.
Note: be sure to spend ten minutes going through the initial setup instructions at the beginning of the watch manual. While the WS4 has display prompts that make it easy to use, the watch, like all ABC watches, must be initially calibrated in order for it to produce valid results.
Lastly, the CR2430 battery is easy to replace using only a coin. The Energizer Watch/Electronic Battery, 3.0 Volts, 2430, 6-Count Pack batteries are inexpensive and available on Amazon.
