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, water resistance 10 ATM/100 m, integrated rubber strap. Brand new with box, documents and official 2-year warranty.
Sirio takes its name from the brightest star in the sky, and like it lives by light. The dial is built around a guilloché pattern of parallel lines beneath a sunray finish: light passes through it and changes tone with every movement of the wrist, from light to dark, never flat. The applied indices and hands feature luminous 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, and drilled lugs that allow easy strap changes. The screw-down case back houses a mineral glass window from which you can observe the Japanese automatic movement at work, with the oscillating weight winding on every gesture.
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.
