The big case GAX100, whose combination analog and digital format delivers the information you need in an instant. The model was inspired by the ever-changing spectacles on display in the great natural beauty of Hawaii. Black semi-transparent resin is formed using mixed color molding that reproduces the twilight gradations reflecting off of a big wave. Function-wise, this model comes equipped with Tide Graph, which is a must for surfers. The GAX100 has a dial at 10 o’clock that is an analog tide graph. Moon Data and temperature measurement also provide intuitive tide information that supports your rides, no matter where they take you.
