The Grand Seiko SBGN013 is encased in 40mm of stainless steel surrounding a black dial on a stainless steel bracelet. Features of this Grand Seiko Heritage Collection 9F Quartz GMT include hours, minutes, seconds, date and GMT. This Grand Seiko watch also measures 12.4mm in thickness and 46.7mm from lug-to-lug.

This time piece features the 9F86 Calibre which is based upon, and has all the precision and durability attributes of, the original 9F but incorporates a GMT function that allows the watch’s precision to be maintained when the hour hand is adjusted independently. This is made possible by new components that have been created especially for this movement.
The watch allows you to move the hands without stopping the watch when setting it to local time. This achieves a convenience in which excellent accuracy of the quartz watch won’t be lost.
