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
Automatic watch of 40 mm in stainless steel with brushed and polished finish, silver dial with guilloché work and sunray finish, Japanese automatic movement visible through the exhibition caseback, anti-reflective mineral glass, water resistance 10 ATM/100 m, integrated steel bracelet Norton design. New with box, papers and official 2-year warranty.
Sirio takes its name from the brightest star in the sky, and like that it lives by light. The dial is built around a guilloché pattern of parallel lines under a sunray finish: the light passes through it and changes tone with every movement of the wrist, from light to dark, never flat. The applied indices and hands have luminous treatment, and the printed minute track completes the dial with instrument-level precision.
The case is 40 mm stainless steel, with alternating brushed and polished surfaces that define the sporty-elegant character. The screw-down back features a mineral glass window from which the Japanese automatic movement can be observed at work, with the rotor winding on every gesture.
The bracelet is stainless steel designed to fit this case, integrated into the profile of the lugs and finished with the same alternating brushed and polished surfaces: not a borrowed bracelet, but part of the watch’s design. The silver dial is the brightest and most versatile version of the range: it changes with ambient light, from warm white to steel gray, and goes well with anything you wear.
