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 - Automatic Miyota 8215 - Steel - Integrated Bracelet - 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 crystal, water resistance 10 ATM/100 m, integrated steel bracelet designed by Norton. New with box, papers and official 2-year warranty.
Sirio takes its name from the brightest star in the sky, and like that star it lives on light. The dial is built around a guilloché linear 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-precision.
The case is 40 mm stainless steel, with alternating brushed and polished surfaces that define a sport-elegant character. The screw-down case back houses a mineral glass window through which the Japanese automatic movement can be observed at work, with the rotor winding on every gesture.
The bracelet is stainless steel, custom-designed for this case, integrated into the lugs’ profile and finished with the same alternation of brushed and polished surfaces: not a strap adapted to the case, but part of the watch’s design. The silver dial is the brightest and most versatile version of the line: it changes with ambient light, from warm white to steel gray, and pairs well with anything worn.

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.
