Grand Seiko GMT Quartz SBGN013

The SBGN013 holds a significant place in Grand Seiko’s lineup as the first 9F quartz GMT model introduced to the Heritage Collection. The Calibre 9F86 is based on the renowned 9F movement, known as one of the world’s most advanced quartz calibres with an accuracy of ±10 seconds per year. The GMT function allows the hour hand to be adjusted independently without stopping the movement, preserving the watch’s precision while travelling.
