Expressing the dynamism of waterfall spray Platinum lacquer finish

Makie is a technique in which a picture is drawn on the surface of a vessel with lacquer, and metal powder is sprinkled before the lacquer dries to create a pattern. The sapphire glass bezel has been given a maki-e finish with the cooperation of Mr. Yutaro Shimode, a master of Kyoto maki-e. The scenery of a waterfall with splashes is expressed with the exquisite density of the platinum powder that is sown. Mr. Shimode himself named it "Makiboke Nuki Gakitakimon". The craftsmanship and sensibility of the craftsmen are alive and carefully done one by one by the hands of craftsmen to create expressions unique to one-of-a-kind items.

Bezel components displaying on the OCWS5000MB

Original OCEANUS blue

A unique process was devised to apply the maki-e to the bezel. On the back of the beautifully polished sapphire crystal bezel, a newly developed translucent gradation vapor deposition is applied, and craftsmen apply platinum powder to the lacquer work. Finally, by painting black, the OCEANUS blue that changes from blue to black and the glittering lacquer work appear in it. In addition, the inside of the sapphire ring is polished to create a beautiful finish that reflects the sparkle of the lacquer work in three dimensions. Gradation vapor deposition intentionally makes the direction of color change oblique to express the dynamism of flowing water.

Inspired by mother-of-pearl white mother of pearl dial

In order to express the dynamism of the sparkling water flowing down, the dial is decorated with white mother of pearl shells. Inspired by the mother-of-pearl mother-of-pearl used in traditional crafts such as lacquerware, a jet-black mirror dial with slit-like gaps is layered on top of a mirror-finished pearl oyster shell that enhances color development. The iridescent luster echoes with the sparkle of the lacquer work, creating a mysterious waterfall scene.
