This certificate accompanies your watch. It shows the precision values achieved by the movement before it was cased and that the movement met the Grand Seiko Standard. The precision tests were conducted in an artificially controlled environment in our facility. The certificate shows the caliber number, the movement’s individual number and the case’s individual number.
Normal usage accuracy of a mechanical watch varies depending on individual customer’s use conditions such as winding state of the mainspring by movement amount of the customer’s arm per day, temperature environment, and position (orientation of a watch). Accordingly, the actual normal usage accuracy when the watch is used by a customer may differ from the numerical value of each item specified in the Grand Seiko Standard.
CAUTION
Your Grand Seiko Inspection Certificate is unique and cannot be replaced or reissued if lost or after maintenance or adjustment.
