Timex WS4 User Manual

“When the alarm beeps you know you’ve reached your set altitude. This quick reminder will allow you to assess your condition and decide if you are on track for a successful ascent.” 
-Conrad Anker World-Renowned Mountaineer
To set the Target Altitude or Altimeter Alarm: 
1. Press MODE until ALTI is shown. 
2. Press and hold SET to start.
3. Press START/SPLIT (+) or STOP/RESET (-) to increase or decrease setting   values.  
When the watch reaches the current altitude display you can also:

As it is an inverse relationship between altitude and barometric pressure, if I wake at the same or lower elevation I can be confidentthe atmospheric pressure has remained constant. If I rise to a higheraltitude I need to be aware as there is a chance a low pressure ismoving in.” 
-Conrad Anker World-Renowned Mountaineer
BAROMETER MODEYour watch includes information about current and sea level pressure, high or
low barometric information, and changes in sea level pressure over the most
recent 36 hours....

You only need to calibrate the barometer OR altimeter, since they rely on the same pressure. See Calibration Mode on page 36 formore information.
TEMPERATURE AND FORECASTIn TIME, ALTI, BARO, CHRONO, and TIMER Modes, your WS4™watch includes
information about temperature and forecast.  
The watch can predict the weather based on historical air pressure trends. 
Generally, if the air pressure is rising, the weather situation is considered to be
improving and is indicated by the sun icon. If the air pressure...

COMPASS MODEThe WS4™watch includes an accurate digital compass that takes a reading 
every second when engaged and shows the compass reading as a number and
a cardinal heading along with a virtual compass needle. You must calibrate the
compass prior to first use and it’s also a good idea to calibrate it periodically to
maintain more accurate readings. For more information, see Calibration Mode
on page 36. 
Calibrating the Compass 
When using the compass, it’s important to keep your wrist at a level,...

TIP: Your watch would be a great tool for orienteering. You can use 
your compass to navigate way points and if you participate in an orienteering race, you can time yourself using the chronograph(see next section). 
CHRONO MODEYour watch includes a chronograph, which is a stopwatch function. The chrono
can track up to 100 hours and 99 laps. The data you collect while running the
chronograph can then be used to check your progress in Review Mode.

make sure bad weather is not approaching. Once you’ve finished, you can check out information about your activity in Review Mode.
Laps and Splits 
When referring to lap times, this is the time for an individual segment of an 
activity. Split time is the entire time up to the current segment.
When the chrono is running, a bar is shown in chrono and time of day modes above the stopwatch icon. 
NOTE: 
Your chronograph can be a good tool for mountain  
biking, skiing, or trail running. You can take...
