Never send sentimental or engraved items for repair as your watch could be replaced and the original may not be returned to you.
Repair charges vary depending upon the style, age, and condition of the watch.
In most cases, problems with your watch in the first year will be covered by the terms of Timex's limited warranty. You will not have to pay for repairs to your watch that are covered by the warranty. There is, however, a $8.00 charge to cover postage and handling as specified in the warranty (US customers only).
Approximately 2-4 weeks.
