Length adjustment service for metallic bands is available at the retailer from whom the
watch was purchased. If you cannot have your watch repaired 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.
If your watch has a protective lm for preventing scratches, make sure to peel it o
before using the watch. If the watch is used with the lm on it, dirt, sweat, dust, or
moisture may be attached to the lm and may cause rust.
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.
