DUAL PERSONALITY
Simply refined by day, visually captivating by night. The Sigma Date Calendar Luna White showcases 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. It glows brilliantly while maintaining the disciplined design 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 features a premium-grade Miyota Calibre 9015, an automatic self-winding movement with a custom oscillating weight finished in satin-brushed and sandblasted treatments. Fully assembled in Japan, it is the thinnest high-beat automatic calibre Miyota has ever created. 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. 

SEAMLESS CRAFT
One of its key features is a sleek, seamless stream of single steel links, perfectly integrated with the case. Super slim and equipped with a quick-release, micro-adjustable system, it ensures a precisely tailored and comfortable fit on the wrist.
