Thank you very much for choosing
a Grand Seiko watch.
For proper and safe use of your Grand Seiko watch,
please read the instructions carefully in
this booklet before using it.
Keep this manual handy for easy reference.
Bracelet sizing is available at the retailer from whom the watch was purchased. If you cannot
have your watch band sized by the retailer from whom the watch was purchased because you
received the watch as a gift, or you moved to a distant place, please contact Grand Seiko
international service network mentioned on CERTIFICATE OF GUARANTEE or our website.
The service may also be available on a chargeable basis at other retailers, however, some
retailers may not undertake the service.
The battery in your watch at the time of purchase was inserted in the watch at the factory for
performance checks. Battery replacement is at cost even within the guarantee period.
If your watch has a protective film for preventing scratches, make sure to peel it off before using
the watch.
If the watch is used with the film on it, dirt, sweat, dust, or moisture may be attached to the film
and may cause rust.
