I changed the battery in the watch and don't know how to set it. I keep getting an ERROR and won't connect!
You can get a new battery for your Casio 2638 G-Shock watch at most jewelry store. The jewelry department at Walmart and Target sells batteries for Casio watches.
Casio has a digital watch that claims 10 yrs of battery life.
To replace the battery in a Casio 1827 watch, place a soft cloth under the face of the watch to prevent scratches. Locate the small dent on the back of the watch and slide the blade of the knife under the back so that it pops off. Remove the old battery, replacing it with a new one and returning it to the same position. Replace the back of the watch.

Are you serious?
The Atomic watch by Casio receives a time calibration signal six times a day to ensure time accuracy. Many models also have a rechargeable solar power battery.
Casio is a watch factory from Korea
Yes, the casio watch has a built in shock absorber.
What battery goes into a Colibri Sport 2000 stop watch made in Hong Kong about 20 years ago and where is the battery inserted? Thank you. fmeares@hotmail.com
No. the battery could potentially last for more than 40 years, so long as it's regularly charged. However, these watches have only been around for 10 years so we'll have to see if any make it to the year 2040! In all probability, some other part of the watch will break first. (Casio claim the battery will last as long as the watch itself).
You can purchase Casio watch bands online from the official Casio website. You can also purchase them from personal sellers at eBay as well as Craigslist.
