The Sigma Date Calendar features a symmetrical octagonal case with rounded corners and a circular bevel-edged bezel, finished in harmonious blends of satin and mirror polishes. It embodies TIGA's design philosophy and approach to contemporary sophistication and is engineered with modern, minimalistic elegance.

This model features a sandblasted textured dial with a die-cut design on the hour markers and a date window at the 6 o'clock position. The die-cut slats treatment offers a detailed glimpse of the date calendar wheel, integrating practical function with visual aesthetics. The hands and additional hour markers are filled with white Swiss Super-LumiNova, which emits a turquoise glow in the dark.

Powered by an automatic self-winding Miyota Calibre 9015, it is decorated with an original designed rotor that is visible through its exhibition sapphire crystal case back.
