The SBGA427 is the latest addition to Grand Seiko's USA-Exclusive 'Seasons' (or 'Sekki') collection, highlighting the ever-changing nature of the seasons. Each timepiece, design and movement in the ongoing collection is a tribute to Japanese nature and expresses the natural and continuous flow of time. Reference SBGA427 is powered by Grand Seiko's 9R65 Spring Drive calibre, which combines the motive force of a mainspring found with the high precision of a quartz watch.
