LUXURIOUS AESTHETICS
The Sigma Date Calendar Graphite Black draws the eye with its unique construction, while the classic black dial offers an exceptionally refined aesthetic, highlighting the grained textures. The contrast between satin-brushed and mirror-polished surfaces further enhances the sleek profile, creating a clean, understated look that defines modern luxury.

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.
