Description from the seller
Norton: over thirty years of Italian watchmaking, where artisanal tradition meets the precision of Japanese and Swiss movements.
In this auction we offer: Norton - Sirio - Automatic Miyota 8215 - Steel - Integrated Bracelet - Exhibition Back - 40 mm - 10 ATM
Automatic 40 mm watch in stainless steel with brushed and polished finish, blue dial with guilloché and sunray finish, visible Japanese automatic movement through the exhibition back, anti-reflective mineral glass, water resistance 10 ATM/100 m, integrated steel bracelet designed by Norton. New with box, documents and official 2-year warranty.
Sirio takes its name from the brightest star in the sky, and like that star it lives on light. The dial is built around a guilloché pattern of parallel lines beneath a sunray finish: light passes through it and changes shade with every wrist movement, from light to dark, never flat. Applied indices and hands are luminescent, and the printed minute track completes the dial with instrument-grade precision.
The case is stainless steel, 40 mm in diameter, with alternating brushed and polished surfaces that define the sporty-elegant character. The screw-down caseback carries a mineral glass window from which the Japanese automatic movement can be observed at work, with the rotor winding with every motion.
The bracelet is stainless steel, custom-designed for this case, integrated into the profile of the lugs and finished with the same alternation of brushed and polished surfaces: not a modified bracelet, but part of the watch’s design. The blue dial shifts from deep blue to near-black toward the edges, with the sunray finish that brightens the center when it catches the light: the most classic and sober variant of the line, one that never tires.
