As an authorized service agent, Swiss Service Center, Inc. provides full factory warranty repair on Omega, Rado, Longines, Tissot, and Hamilton watches. To qualify under the terms of a factory warranty, you will need to supply the warranty card or book and the original sales receipt along with your watch when sending it in for repair. Please do not ship your watch in its display box, since all packing materials are discarded. Please use our Swiss Service Mail-In Repair Form to ensure that we have all of the information we need, including your daytime phone number.
