Marble-W is Azusa's first watch for women, with a mother-of-pearl dial. As a piece for sharing its world, we also offer it as a matching set with the men's model, ORTHODOXY Pearl & Blue. The mother-of-pearl glow, shifting with the angle of the light, makes each one special—no two ever alike. And on ORTHODOXY Pearl & Blue, an unusual blue rotor lets you enjoy the appeal of a mechanical watch from behind as well. With classic design and a refined touch of individuality, the two make an ideal gift for a wedding, an anniversary, or someone dear.
A special matching gift, for the time two people share.
With classic design and a refined touch of individuality, the two make an ideal gift for a wedding, an anniversary, or someone dear—a matching set for sharing your feelings.
Both watches use natural mother-of-pearl (MOP) for the dial. Its soft glow, shifting delicately with the light, gives each a singular face—no two ever quite alike.
A natural-stone cabochon—ruby or sapphire—on the crown adds a subtle touch of brilliance to the wrist.
ORTHODOXY Pearl & Blue features an unusual blue rotor. The vivid blue glimpsed through the exhibition case back brings out the moving charm unique to a mechanical watch.
Each movement receives additional regulation by our own watchmakers, beyond the factory-standard adjustment—holding down unit-to-unit variation for dependable, consistent accuracy.
