Timex Watch (T2P277) T2P277 Scheda Tecnica

Pull crown all the way out. The upper and lower retro-

grade hands reset to the start of their scales automati-

cally. Indicator hand (4th center hand) should point to 12 

o’clock. If it does not, press either A and/or B button to 

move hand until it points to 12 o’clock. A and B buttons 

move hand clockwise and counterclockwise, respectively. 

Hold button to move hand fast. Push crown in when done.
ALTIMETEr CALIBrATIon

Before use, the altimeter must be calibrated.
Since an altimeter uses pressure to determine the altitude 

and pressure varies from place to place, it is important to 

set the altimeter to a known reference altitude value, or 

to a standard reference altitude of a given place. Sudden 

changes in pressure due to changes in weather can cause 

your altimeter reading to be off by +-100m (328 ft), even 

if your location has not changed. Recalibrate to a known 

altitude when drastic pressure changes occur.
To calibrate the altimeter:
1.  Pull the crown to its middle position and wait for the 

indicator hands to stop moving.

2.  If the altimeter was OFF at the moment of crown 

pulling, the lower retrograde hand will point to the unit 

selected the last time the altimeter was used, other-

wise the lower retrograde hand points to the current 

selected unit in altitude display. The 4th center hand 

and upper retrograde hand should point to the current 

altitude.

3.  Press A or B to move the 4th center hand counter-

clockwise or clockwise, respectively, until it points 

to the desired calibration altitude. Holding A or B
