SIGMA DATE CALENDAR
CONTEMPORARY EXPRESSION THROUGH COLOUR
Introducing the SIGMA Collection. Our very first series focuses on contemporary aesthetics whilst embodying minimalist elegance. From the selection of alluring dial colours to the finishing and treatments, SIGMA is a testament to our dedication to TIGA's design language and horological culture. This collection is dedicated to enthusiasts who appreciate the perfect balance of form and function.
PERFECT DESIGN INTEGRATION
The SIGMA Date Calendar showcases a perfect integration of design aesthetics and function. Rather than traditionally being a mere hidden component, the date functions of the calibre have been purposely designed to incorporate seamlessly with the dial. Openworked hour markers offer a glimpse of the date wheel and the date-changing process. The date window is finished in fine sand-blasted bevel edges and the decorated rotor is displayed through the exhibition caseback.
DURABLE ELEGANCE
The case and bracelet are forged from 316L surgical grade stainless steel. Grade 316L is known for its excellent corrosion resistance, durability, and low carbon content, making it an ideal material choice for our watch construction. The perfect balance of satin and mirror finishes facilitates a beautiful dance of light, highlighting the design's elegance and further enhancing the sleek lines.
ULTRA-THIN JAPANESE PRECISION
Driven by an ultra-thin 3.90mm Japan-assembled Miyota Calibre 9015 - a three-hand automatic movement with a date calendar function. The unidirectional winding creates a distinctive sound as it smoothly engages and disengages from the winding system and reduces friction losses, as no reversing gear is required. With a high beat frequency of 28,800 vph, it offers a maximum power reserve of 42 hours. The calibre is decorated with a satin-polished and sand-blasted rotor, adding a contemporary touch to the exhibition caseback.
REFINED RADIANCE
The hour markers and the hour and minute hands are filled with Swiss Super-Luminova® BGW9 Grade A. The multiple printing passes of the luminescent material increase the intensity and longevity of the glow. The minimalistic luminous design with BGW9 casts a captivating turquoise glow in the dark.
AESTHETICS MEET PRACTICALITY
The bracelet is specifically engineered and designed to align seamlessly with the aesthetics of the case. Its slim, single-link design offers a comfortable and perfect fit on any wrist. Additionally, the short link design and the micro-adjustable clasp further enhances the flexibility of bracelet adjustments. Each of the link's edges are chamfered and finished in mirror polish, creating intriguing contrasting details that further elevate the visual appearance of the timepieces as they interact with light.
