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 - Exhibition Case Back - 40 mm - 10 ATM
40 mm automatic watch in stainless steel with black IP finish, brushed and polished, black dial with guilloché pattern and sunray finish, visible Japanese automatic movement through the exhibition case back, anti-reflective mineral glass, 10 ATM/100 m water resistance, integrated rubber strap. Brand new with box, documents and official 2-year warranty.
Sirius takes its name from the brightest star in the sky, and like that, it thrives 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. 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 black IP finish, brushed and polished, and drilled lugs that allow easy strap changes. The screw-down case back houses a mineral glass window from which the Japanese automatic movement can be observed at work, with the rotor winding at every gesture.
The total black is the boldest version: case, dial and indices in the same dark tone, where the guilloché reads not as color but as relief, revealing itself only when light cuts it from the side.
