AI-assisted summary
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 - Miyota 8215 Automatic - Black PVD - Sunray Guilloché dial - See-through caseback - 40 mm - 10 ATM
40 mm stainless steel automatic watch with a black IP finish, brushed and polished, black dial with guilloché work and sunray finish, Japanese automatic movement visible through the see-through caseback, anti-reflective mineral glass, 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 that one it lives by 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 indices and hands feature luminescent treatment, and the printed minute track completes the dial with instrument-like 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 caseback features a window in mineral glass from which the Japanese automatic movement can be observed at work, with the rotor winding with every gesture.
The total black version is the most bold: case, dial and indices in the same dark shade, where the guilloché reads not as color but as relief, revealing itself only when light cuts it from the side.

Seller's Story
NORTON — WE ARE THE CREATORS OF THE BRAND
We are the creators and owners of the Norton brand, with a watchmaking history that traces back to the Nineties. We design and personally curate every timepiece, from material selection to final quality check before shipping.
Our philosophy blends Italian artisanal tradition with the precision of Japanese and Swiss movements. We select high-quality materials — stainless steel, sapphire and domed mineral glass, ceramic and aluminum bezels, worked dials, genuine leather straps and solid bracelets — and we take care of every detail, even those that aren’t visible.
The collection ranges from water-resistant automatic divers to vintage-inspired chronographs, from GMTs for travelers to collector pieces with sapphire cases. Several models are limited editions, numbered, produced in only a few dozen or a few hundred pieces.
All our watches are new, unworn, and come in the original Norton Watchmaker box with official two-year warranty and documents.
WHAT YOU WILL RECEIVE
- A new, unworn watch with protective films applied.
- Original packaging, manuals, and official two-year warranty.
- Shipment within 3 working days from payment, with tracking communicated via the Catawiki system.
IMPORTANT NOTES
Limited editions: the progressive number engraved on the case back is assigned based on warehouse availability at the time of shipment. It is not possible to choose it.
Screwed case backs: they are screwed down to the end of travel to ensure water resistance, so the position of the engravings may differ from catalog images.
Returns: accepted only if the protective films have not been removed and the watch and its box are in the same condition as when shipped.
Non-EU Buyers: customs duties and import charges are the responsibility of the buyer.
We respond to messages Monday to Friday, within 24 hours. We are available before and after the purchase for any questions.
