About the caliber number
The caliber number is a four-digit number that indicates the model of a
movement (mechanical part of a watch). The Grand Seiko watch is mounted
with an exclusive caliber. The mechanical caliber number starts with "9S", the
spring drive caliber number starts with "9R" and the quartz caliber number
starts with "9F".
※ Some quartz caliber number starts with "8J" or "4J".
How to check the caliber number
The four-digit model number on the case back is the caliber number.
In the case of mechanical models, the attached "Grand Seiko Standard
Inspection Certificate" is printed with "Caliber No." So, the caliber number can
also be checked on the certificate.
