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 - Black PVD - Sunray Guilloché Dial - Ex exhibition caseback - 40 mm - 10 ATM
40 mm automatic stainless steel watch with black IP coating, brushed and polished finish, black dial with guilloché work and sunray finish, visible automatic movement through the display caseback, anti-reflective mineral glass, water resistance 10 ATM/100 m, integrated rubber strap. New with box, documents and 2-year official warranty.
Sirius takes its name from the brightest star in the sky, and like that star it lives on light. The dial is built around a parallel-line guilloché pattern beneath a sunray finish: light passes through it and changes tone with every wrist movement, from light to dark, never flat. Applied hour markers and hands feature luminous treatment, and the printed minute track completes the dial with instrument precision.
The case is 40 mm in stainless steel with black IP finish, brushed and polished, with drilled lugs that allow easy strap changes. The screw-down caseback features a mineral glass window from which the Japanese automatic movement can be observed at work, with the rotor winding with every gesture.
The total black version is the boldest: case, dial and indices in the same dark shade, where the guilloché reads not as color but as relief, revealing itself only when light slices it from the side.
