The stainless-steel bezel is first treated with recrystallisation and deep-layer hardening processes to form a hard layer on the surface of the material and create a unique, brilliantly gleaming texture. Then, a rainbow IP coating is applied to the surface to express the look of the aurora borealis as seen from outer space. With its impressive beauty of form, the watch demonstrates a dedicated passion for design in its materials, colours, and finishes.

*The stainless steel is processed into components and then recrystallised, yielding unique differences in crystalline grain. This makes the pattern, colour tone, and lustre differ subtly from part to part.
*The look of the rainbow IP colour will vary from watch to watch.

Deep-layer hardening process (stainless steel)
This technology creates a hard layer by infusing carbon into the surface of the steel. Unlike coatings, the process delivers enhanced strength by hardening the material itself.

The Dual Core Guard structure protects the module with a carbon fibre-reinforced resin case and encloses the case with metal components. The side of the case back is raised to serve as the lugs that connect the bands to the case and as the guards for the crown and buttons. While delivering enhanced rigidity, integrated moulding also helps make the watch so compact and lightweight.

While maintaining shock resistance, we optimised the circuit board layout by using smaller, slimmer parts and integrating electronic componentry with high-density mounting technology. This multi-hand chronograph offers a slim, compact profile, while still packing a punch with functions like Smartphone Link and solar-powered radio control.
