Founded in 1981, Guess is a luxury American clothing and accessories manufacturer. Guess added luxury wrist watches to their accessories line in 1984. When the battery in your Guess watch finally runs down, you can change it at home in less time than it would take to have a professional jeweler do the job. The process is simple, requires no previous watch-repair experience, and can be completed in less than 10 minutes. Opening the watch yourself may void the warranty, however.
Items you will need
Pocket handkerchief or optical cloth
3-tipped watch-case-opening tool
Plastic needle-nose tweezers
Optical-sized flathead screwdriver
Place your Guess watch face-down on a flat surface, such as a table or countertop, that has been cushioned with a pocket handkerchief or soft optical cloth.
Note the positioning of the notches on the back of the watch case. Manipulate the tips of a three-tipped watch-case-opening tool to align with the notches.
Insert the tips of the tool into the notches on the back of the Guess watch case. Tighten the tool's grip on the case by twisting the knob at the end of the tool. Twist the tool to the right to pop the cover off of the back of the watch case; set the back cover aside.
Pull the rubber gasket and plastic plate out of the Guess watch case with a pair of plastic needle-nose tweezers; work carefully to avoid damaging these essential components. Set the rubber gasket and plastic plate aside; the watch's battery compartment will now be visible.
Raise the metal latch covering the battery compartment with the tip of an optical-sized, flathead screwdriver. Use the small flathead screwdriver to pry the old battery out of the battery compartment. Insert a new battery, and lower the metal latch to hold the battery in place.
Cover the battery compartment with the plastic plate, followed by the rubber gasket. Place these components into the watch case, using the plastic tweezers.
Replace the watch's back cover to complete the battery-replacement process. Place the cover over the back of the watch case, and pinch the case between your fingers until it snaps into place.
Open the watch case with a pair of needle-nose jewelry pliers if you are unable to find a three-tipped watch-case-opening tool.
Guess recommends having a professional jeweler replace your watch battery. Doing the job yourself may void its manufacturer's warranty. Contact Guess Watches customer service for more repair and warranty information.
