Norton Sirio Automatic, reference NW.SIR.SLB (Silver), 40 mm stainless steel case with automatic Miyota 8215 movement, silver guilloché sunray dial, integrated steel bracelet, 10 ATM water resistance, new with original box, papers and 2-year official warranty, period beyond 2025.
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 - Sirius - Automatic Miyota 8215 - Steel - Integrated Bracelet - Exhibition case back - 40 mm - 10 ATM
Automatic 40 mm 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 stainless steel bracelet designed for Norton, New with box, documentation and official 2-year warranty.
Sirio takes its name from the brightest star in the sky, and just like it, lives by light. The dial is built around a guilloché pattern of parallel lines under a sunray finish: light passes through it and changes tone with every wrist movement, from light to dark, never flat. Applied indices and hands feature lume, and the printed minute track closes the dial with instrument-grade precision.
The case is 40 mm stainless steel, with alternating brushed and polished surfaces that define the sport-elegant character. The screw-down case back mounts a window in mineral glass through which the Japanese automatic movement can be observed at work, with the rotor winding on every movement.
The bracelet is stainless steel, custom-designed for this case, integrated into the lugs’ profile and finished with the same alternation of brushed and polished surfaces: not a modified bracelet, but part of the watch’s design. The silver dial is the brightest and most versatile in the range: it changes with ambient light, from warm white to steel gray, and goes with whatever you wear.
