HANDS ON WITH THE GRAND SEIKO AUTOMATIC LIMITED EDITION BLUE GS DIAL SBGR097 – 42MM 9S61 NO DATE
2015 marked not only the 55th Anniversary for Grand Seiko, but also the 5 year anniversary of the introduction of the 9S65 caliber. The advantage of the 9S65 as compared to the previous 9S5 series was the use of Spron 610 for the hairspring. They also had a 72 hour power reserve (which was originally introduced in the 9S67 in 2006), due to their in-house manufactured mainspring, Spron 510. Today we introduce you to a model that commemorates both anniversaries… The SBGR097.
