When the watch displays “

LOW BATT

” (as in the figure below), the battery in 

your watch needs to be replaced. To maintain its water resistance, professional 

battery replacement service is advised. Improper battery replacement or service 

will void the warranty.  In the case of self replacement, removal of the old battery 

should be documented in detail to ensure proper replacement of new battery, position 

of contacts, and O-ring line-up. To maintain the watch’s water resistance, it is a good 

idea to smear a small drop of silicone lubricant spray on the O-ring.

Note: 

After the first low battery warning comes on for 15 minutes, the 

EL

,   

    

      Humidity & Temperature

 features will be turned off to conserve the 

          battery power.
