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 Caseback - 40 mm - 10 ATM
40 mm automatic watch in stainless steel with brushed and polished finish, silver dial with guilloché pattern and sunray finish, Japanese automatic movement visible through the exhibition caseback, anti-reflective mineral glass, water resistance 10 ATM/100 m, integrated steel bracelet designed by Norton. New with box, manuals 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 linear 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-grade precision.
The case is 40 mm stainless steel, with alternating brushed and polished surfaces that define the sporty-elegant character. The screw-down caseback houses a window in mineral glass from which the Japanese automatic movement can be observed at work, with the rotor winding with every gesture.
The bracelet is stainless steel, custom-designed for this case, integrated into the lugs and finished with the same alternation of brushed and polished surfaces: not a bracelet adapted to the watch, but part of the watch’s design. The silver dial is the brightest and most versatile version in the range: it changes with ambient light, from warm white to steel gray, and goes with anything you wear.
