The dial of this “Great Blue” edition is reminiscent of the ocean’s surface seen from just below it. You can see the light penetrating it and gradually getting dimmer and darker. The top half also shows wave-like ripples, a cool touch that adds character and depth to it. The applied markers and hands are finished with LumiBrite of course, and the sapphire crystal has a loupe over the day and date window. Inside ticks the familiar 4R36 automatic movement, running at a frequency of 21,600vph and offering a power reserve of 41 hours. The back of the case is solid, so you don’t see the movement at work.
