FEATURES
Spring Drive GMT with an innovative heart in a classic attire
It is a model with a classic design and ultimate function. Designed with a simple 24 o'clock scale, the GMT indicator creates stark legibility without breaking the formal expression. This model incorporates Grand Seiko’s unique Spring Drive caliber, which combines the motive force of a mainspring with the high precision of a quartz watch, while also offering the GMT function that the international traveler needs to ensure that the accuracy of the time shown is not compromised when the time zone is changed.
