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 - Black PVD - Guilloché Sunray Dial - See-through Case Back - 40 mm - 10 ATM
40 mm automatic watch in stainless steel with black IP finish, brushed and polished, black dial with guilloché work and sunray finish, Japanese automatic movement visible through the see-through case back, anti-reflective mineral crystal, water resistance 10 ATM/100 m, integrated rubber strap. New with box, papers and official 2-year warranty.
Sirio takes its name from the brightest star in the sky, and like it lives on 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 wrist movement, from light to dark, never flat. The applied indices and hands feature luminescent coating, and the printed minute track completes the dial with instrument-grade precision.
The case is 40 mm stainless steel with black IP finish, brushed and polished, and drilled lugs that allow easy strap changes. The screw-down case back mounts 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 is the boldest version: case, dial and indices in the same dark shade, where guilloché is read not as color but as relief, revealing itself only when the light strikes it from the side.
