The dual-coil motor is used for the in-dial motor at 3 o’clock, and the world time can be displayed in a shorter time. In addition, the speed of the hand movement can be slowed down to express the original movement of the hand, and to operate the clock. The value of “fun” has been newly added. In terms of design, we adopted an elegant and beautiful round index, pursued a sense of detail and three-dimensionality, and paid particular attention to detail. In addition, the dial at 3 o’clock has a world time of 12 hours that allows you to intuitively check the time. Like the Oceanus manta ray, we are particular about blue coloring and use sputtering (*) to beautifully express the blue symbolizing the brand identity. Dual curve sapphire glass with anti-reflective coating on both sides, rough polishing that requires skill, case with DLC and titanium carbide treatment to prevent scratches, band, and high quality finish.
