The 2026 Norton Sirio - Automatico, reference NW.SIR.SLB (Silver), is a new 40 mm stainless-steel watch with a Japanese Miyota 8215 automatic movement.
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 are offering: Norton - Sirio - Miyota 8215 Automatic - 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 to 10 ATM/100 m, integrated stainless steel bracelet in the Norton design. New, with box, documents and 2-year official warranty.
Sirio takes its name from the brightest star in the sky, and like that star, it lives by the light. The dial is built around a parallel-line guilloché pattern beneath a sunray finish: light moves across it and changes its tone with every movement of the wrist, from light to dark, never appearing flat. The applied indices and hands feature luminous treatment, while the printed minute track frames the dial with instrument-like precision.
The case is 40 mm stainless steel, with alternating brushed and polished surfaces that define its sporty-elegant character. The screw-down caseback features a mineral glass window through which the Japanese automatic movement can be seen at work, its oscillating weight winding the watch with every movement.
The stainless steel bracelet is custom-designed for this case, integrated into the profile of the lugs and finished with the same alternation of brushed and polished surfaces: not an adapted bracelet, but part of the watch's design. The silver dial is the brightest and most versatile version in the range: it shifts with the ambient light, from warm white to steel grey, and goes well with anything you wear.
