It is time for battery change..... This time it is my Precista W10 watch. This is not a detail step by step procedure. You can see some of the steps here...
The basic steps are the same. :)
My Precista 6bb watch.
Remove the NATO strap.
Gain access to the battery compartment cover.
The new battery.
The battery compartment and the cover. Don't forget to lubricate the gasket on the cover.
The new battery in place. Check to make sure the battery works before you close up.
All done. :)
