MTGB3000 Series – MTGB3000PRB1 Monica Jewelers

Immerse yourself in stunning structural and luminous beauty — metal meets resin in a very special textural MT-G timepiece inspired by the aurora borealis.

The stainless steel bezel is treated first with recrystallization and deep-layer hardening processes, then a rainbow ion-plated (IP) coating is applied for an extraordinary top bezel developed with just this design in mind. Each timepiece is a one-of-a-kind, thanks to the unique differences in crystalline grains*1 and rainbow IP colors.*2

Elaborate finishing takes this timepiece to an entirely other level. The case back, made of stainless steel treated with rainbow IP, is then repolished to remove the coated layer from only the raised portions on the back of the case. The mysteriously beautiful aurora borealis colors are also captured in the new purple hue of the translucent soft urethane band paired with the rose gold-colored ion-plated band loop and purple ion-plated buckle. The MTGB3000 design invites you to join the dance of color in the aurora borealis as seen from outer space.

*1 The stainless steel is processed into components and then recrystallized, yielding unique differences in crystalline grain that make for subtle differences in pattern, color tone, and luster from part to part.
*2 The look of the rainbow ion-plating color will vary from watch to watch.
