What makes Grand Seiko 9S mechanical special?
#GrandSeiko #Mechanical #9S
Every one of the 200 or more components in a mechanical watch are critical to its performance and durability but none more so than those that make up the regulator and escapement mechanisms.
When the 9S caliber was designed, these were engineered anew. With the subsequent creation of the 9S85 Hi-beat caliber, new materials and new manufacturing techniques were used, further enhancing the performance of these key parts and these latest materials and techniques are now incorporated in all 9S movements, greatly increasing both their power reserve and their precision.
