A moon in the silence of the night

While evoking the M45 (classic), it expresses simplicity (silence) with minimal design. The world of a lone moon floating in the night sky is created through the shapes, textures and colors.

A new allure of the moon phase, shaped by exquisite craftsmanship and white mother-of-pearl

A moon phase wheel with a glossy finish, studded with stars, and a gently shining moon made of white mother-of-pearl(MOP). Moon phase with a structure designed to achieve precise expression (patent pending)

70-hour power reserve, crafted with a distinctive design.

Newly developed hand-winding moon phase movement, equipped with a silicon escape wheel developed in-house, achieves a power output of 70 hours. The cutout through which the wheel can be seen is shaped like a crescent moon. The width of the wave pattern changes intermittently to evoke the trail of stars.
