UNDERSTATED ELEGANCE
The Sigma Date Calendar Royal Blue features a unique colour that shifts between deep blue and soft violet. The dial carries a distinct aesthetic, and this regal blue enhances its dialogue with the watch’s steel finishing. It remains subtle, understated, and luxurious — without ever venturing into flamboyance.

PRECISION ENGINEERED
The Sigma Date Calendar 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.

LOW-LIGHT BRILLIANCE
The Sigma Date Calendar applies multiple layers of Swiss Grade-A Super-LumiNova® to its hour markers and hands. This meticulous application ensures lasting luminosity, giving the watch a strong and confident presence in low-light conditions.

SEAMLESS CRAFT
One of the key features is its sleek, seamless stream of steel links that is 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 your wrist.
