It's amusing to read a review where someone mentions changing the battery in a 900s model over 10 years...
IT'S NOT A BATTERY!

IT'S A RECHARGEABLE BATTERY! It would have been enough to leave it on the windowsill for a few days and the charge would be like new, considering that these rechargeable batteries rarely last less than 15 years.
Yes, the watch will probably get worn out faster!
During the autumn-winter, the charge dropped by a quarter
(I specifically keep it in a dark place because I'm curious)
BATTERY, SOLAR BATTERY, lunar, tidal boats...
many do not know that this watch has a battery and a solar battery and change the battery after 5-10 years of use.
 i recommend it should buy
In 2009 I bought them for 4,500 rubles.

I’ve been wearing it every day for nine years now, with pennies. In January 19 it will be ten years old, during which time I only replaced the battery once and replaced the strap.
Everything is great. The watch is amazing!!!!!
The only downside is that the watch has run off by almost three minutes in a year, but that’s crap.
use Casio G-Shock G-7900-1 more than year
