*  Before using the water resistance 5, 10, 15 or 20 bar watch in water, be sure the 
crown is pushed in completely.
  Do not operate the crown when the watch is wet or in water. If used in sea water, 
rinse the watch in fresh water and dry it completely.
*  When taking a shower with the water resistance 5 bar watch, or taking a bath with 
the water resistance 10, 15 or 20 bar watch, be sure to observe the following:
  •  Do not operate the crown when the watch is wet.
  •  If the watch is left in warm water, a slight time loss or gain may be caused.  
This condition, however, will be corrected when the watch returns to normal 
temperature.
NOTE:
Pressure in bar is a test pressure and should not be considered as corresponding to 
actual diving depth since swimming movement tends to increase the pressure at a 
given depth. Care should also be taken on diving into water.
TEMPERATURES
and 35°C (41° F and 95°F).
Temperatures over 60°C or 140°F 
(50°C or 122°F for some calibres)  
[for analogue quartz watch 
only]
Your watch works with 
stable accuracy within a 
temperature range of 5° C 
may cause battery leakage or shorten 
the battery life. 
Do not leave your watch in very low 
temperatures below –10° C (+14° F) 
for a long time since the cold may 
cause a slight time loss or gain.
However, the above conditions  will 
be corrected when the watch re
turns 
to normal temperature.
