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 - Sunray Guilloché Dial - Exhibition case back - 40 mm - 10 ATM
40 mm automatic watch in stainless steel with brushed and polished finish, blue dial with guilloché work and sunray finish, Japanese automatic movement visible through the exhibition case back, anti-reflective mineral glass, water resistance 10 ATM/100 m, integrated rubber strap. New with box, manuals and official 2-year warranty.
Sirio takes its name from the brightest star in the sky, and like it lives by light. The dial is built around a guilloché pattern of parallel lines beneath a sunray finish: light passes through it and changes tone with every movement of the wrist, from light to dark, never flat. Applied indices and hands carry luminous treatment, and the printed minute track completes the dial with instrument-grade precision.
The case is 40 mm stainless steel, with alternating brushed and polished surfaces that define the sporty-elegant character and drilled lugs that allow easy strap changes. The screw-down case back features a mineral glass window through which the Japanese automatic movement can be observed at work, with the oscillating weight winding with every gesture.
The blue dial shifts from deep blue to 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 range, one that never tires.
