The U.S. warranty period for Seiko watches sold by Seiko Corporation of America is three (3) years from the date of purchase.

Please examine your warranty closely.
What should I do if my Seiko timepiece needs repair?
The service and repair division of Seiko Corporation of America (SCA) is called Coserv. If you need your timepiece serviced, there are several things you should remember prior to taking or sending it to a Coserv location:

a.) Fully describe the problem or symptoms you are having with the watch or clock.

b.) Include your warranty or proof of purchase if the timepiece is still within the warranty period.

c.) If mailing, make certain your name and address are shown both on the outside of the package as a return address, and on the correspondence inside describing the problem. Also, keep a record of the case number (hyphenated) and the serial number from the back of your watch for reference.

d.) Always insure the package to protect yourself in case of a loss in transit and to make tracing possible if necessary.

e.) Package the timepiece well to protect it in transit.

Should I pack my timepiece in the original gift box?
No. Securely package your watch or clock and ship via UPS, if possible. Gift boxes should NOT be used to return watches.
Will I receive an estimate prior to my timepiece being repaired?
If your timepiece is out of warranty and the repair charges exceed $20.00, you will receive a written estimate outlining all repair costs. You can respond to the estimate by returning the postcard or calling the appropriate service center. If you give instructions in your letter that no estimate is required, regardless of cost, no estimate will be given and the repair will be forwarded to the repair shop for service.
Can new watches be purchased at Coserv?
No. Coserv is strictly a repair center for Seiko Corporation of America.
Does Coserv accept credit card payments for repair services?
No. Payment can be made by sending a check to the repair facility (made payable to Coserv) or COD (cash or check on delivery).
Do I have to send my watch to SCA's Coserv for a battery change if it is a water-resistant watch or a sport diver's watch or can a dealer do it?
You do not have to send a water-resistant watch to Coserv for a battery change. However, you should have a qualified technician at an Authorized Retailer change the battery. Both water-resistant watches and sport diver watches should be pressure-tested after the battery is changed.
Can I go swimming with a water-resistant watch?
You should check the rating level of your Seiko watch as follows to determine its suitability for exposure to water:
  • Water-resistant to 30 meters (100 feet). Will withstand splashes of water or rain but should not be worn while swimming or diving.
  • Water-tested to 50 meters (165 feet). Suitable for showering or swimming in shallow water.
  • Water-tested to 100 meters (330 feet). Suitable for swimming and snorkeling.
  • Water-tested to 150 meters (500 feet). Suitable for snorkeling.
  • Water-tested to 200 meters (660 feet). Suitable for skin diving.
  • Diver's 150 meters (500 feet). Meets ISO standards and is suitable for scuba diving.
  • Diver's 200 meters (660 feet). Meets ISO standards and is suitable for scuba diving.

Note that a SWIM-SAFEŽ strap is made of genuine leather and is suitable for swimming.
Can you send me an instruction booklet for my watch?
Seiko USA is happy to send an instruction booklet to you if you supply them with the eight-digit number (hyphenated in the middle) located on the back of the case along with your complete mailing address. Or, supply your information at custserv@scamahwah.com.
