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, silver dial with guilloché work and sunray finish, Japanese automatic movement visible through the exhibition case back, anti-reflective mineral glass, 10 ATM/100 m water resistance, integrated rubber strap. New with box, papers and official 2-year warranty.
Sirio takes its name from the brightest star in the sky, and like that star it thrives on light. The dial is built around a parallel-line guilloché pattern beneath a sunray finish: light passes through it and changes tone with every wrist movement, from light to dark, never flat. Applied indices and hands have luminescent treatment, and the printed minute track completes the dial with instrument precision.
The case is 40 mm stainless steel, with alternating brushed and polished surfaces that define a sporty-elegant character and drilled lugs that allow easy strap changes. The screw-down case back features a window in mineral glass through which the Japanese automatic movement can be observed at work, with the rotor winding it up with every gesture.
The silver dial is the brightest and most versatile version of the range: it changes with the ambient light, from warm white to steel gray, and pairs well with anything you wear.
