Watches from the Marc Ecko collection come in a variety of styles and designs, ranging from sports watches to elegant watches to even "dog-tag" necklace watches. It is easy to get help from the company when there is a problem with one of their watches.

Remove the back cover of the watch. You may need to use a coin or something sharp to lift the cover. Once open, remove the battery. If the battery is old, changing it may solve your problems with the watch.

Install a new battery. Batteries can be purchased at jewelry stores or any stores selling batteries; just make sure to get one that is the same size and type as the old one. Check the serial number on the back of your old battery, and find a new battery that matches. Before you replace the back cover, hold the watch in your hand while pressing the battery. If the hands of the watch move, put the back cover on and set the time. If they don't, your watch needs more fixing.

Make sure the watch isn't wet inside. If it is wet, you will need to dry it completely. You can let it air dry or dab it with a paper towel. You may also immerse the watch in some dry, uncooked rice, which will soak up all the moisture. Remove the battery first. Once dry, put the battery in and check if the watch works.

Check to see if the watch isn't simply dirty inside. You will need a tiny screwdriver from a watch repair kit to remove the screws and disassemble the watch. You should only attempt this if you have a lot of experience working with watches. For more complex repairs, visit a watch repair center or a place where Ecko watches are sold, or mail your watch to the Ecko company for repairs, which may be covered by your watch warranty. If you choose to disassemble the watch by yourself, pay attention to where each part goes and make sure not to lose any of the parts. Clean everything using a small brush or cloth, while blowing into it to remove dust.

Put the watch parts back together. Put the battery in and the cover back on. Your watch should be working now.

Call Ecko's customer service line at 800-248- 3775, Monday through Friday, from 9 a.m. to 5 p.m., if you need detailed information on repairing your watch.

Find your original Ecko watch warranty and dated receipt. All Ecko watches feature a limited two-year warranty from the date of purchase. This warranty covers all defects in material or workmanship. The watch will be repaired or replaced if defects occur during this period. The warranty does not cover wear-and-tear, abuse, misuse or water damage. It also does not cover batteries, the case, the crystal, the strap or the bracelet.

Visit the Marc Ecko Time website and download the watch warranty. Print out the warranty information.

Fill out the box on the top right side of the watch warranty, which reads "Watch Repair" and has places to write contact information and the cause of repair. You may already have this form on the back of your original warranty. State whether you need a battery, a case or a crystal, or if your watch is broken. Cut this form out of the warranty page. It should be the size of a postcard.

Pack the watch carefully into a small cardboard box filled with protective filler, such as bubble wrap or newspapers, or in a protective envelope. Include a copy of your receipt, along with the "Watch Repair" form and some form of payment to cover the $7.50 shipping-and-handling fee. You may pay this via check, money order or credit card. If paying by card, also complete, cut out and include the form on the warranty page which asks for your card type, card number, expiration date and signature.

Seal the box or envelope tightly and send it, insured, to the following address:

Callanen International 145 Woodward Ave. Norwalk, CT 06854 Attention: Repair Department

Call the Ecko company customer service line, either before or after mailing in your watch, if you have any questions about repairs. You will not be charged for repairs if the watch is still covered under the warranty.
