DUAL PERSONALITY
Refined by day and illuminated by night, this special edition Luna White features a full-luminescent dial that interacts dynamically with its hollow hands and openworked markers, creating an intricate interplay of light and form in low-light conditions. The luminous composition reveals a striking presence in darkness while preserving the disciplined design language and modern elegance that define the collection.

LUNA WHITE
The Luna White dial is applied with multiple printing passes of Swiss Grade-A Super-LumiNova®, engineered for lasting brightness and an intense glow. The openworked hour markers reveal the underlying grey colour date wheel, creating exceptional depth and visual contrast, whether by day or night.

PRECISION ENGINEERED
This special edition is powered by premium-grade Miyota Calibre 9015, a self-winding automatic movement with our custom oscillating weight finished in satin-brushed and sandblasted treatments. Fully assembled in Japan, it is one of the thinnest high-beat automatic calibres. Each movement is adjusted in-house across six positions to an accuracy of –5~+15 seconds per day.

BRILLIANT PRESENCE
The dial is fully coated with the highest-quality Swiss Grade-A Super-LumiNova®. This meticulous application is deliberate, ensuring lasting luminosity while enhancing the design aesthetic in the dark. The glow is bright and striking, creating a bold visual contrast in low-light conditions. 

UNIFIED FORM
Another defining feature is the sleek, seamless flow of multi-faceted steel links, perfectly integrated with the case. Equipped with a quick-release and micro-adjustable system, it ensures a precise, tailored fit and lasting comfort on the wrist.
