Oris Artelier Calibre 400

Classic proportions, stylish design

The case of the Artelier Calibre 400 measures 40 mm and is crafted from finely polished stainless steel. Its lines are soft, its proportions balanced—perfect for the wrist of watch lovers who appreciate classic shapes. The slim bezel allows the dial to unfold: it comes in subtle silver, blue, or anthracite with a fine sunray finish, applied indices, and a clearly drawn minute track.

The slim dauphine hands, the discreet date window at 6 o'clock, and the domed sapphire crystal with anti-reflective coating underscore the elegant restraint. A transparent caseback offers a view of the movement—a hint of the technological expertise hidden within.

Depending on the model, the watch is combined with an elegant leather strap or a stainless steel bracelet with a butterfly clasp. In both cases, it impresses with its high level of comfort and stylish appeal.

Calibre 400 – a modern manufacture movement

At the heart of the Artelier is the Calibre 400 – an automatic movement developed entirely in-house by Oris. It offers an impressive power reserve of 120 hours (5 days), high rate stability, and a silicon escapement that makes the movement particularly resistant to magnetic fields. The movement architecture is designed for longevity: maintenance intervals of up to 10 years and a 10-year warranty underscore the quality commitment.

With a frequency of 28,800 vibrations per hour, the movement runs smoothly and precisely. The winding mechanism is automatic on both sides, and the energy transfer is low-friction and efficient. The decorated rotor, visible through the glass case back, complements the high-quality appearance even in technical detail.

A watch for lovers of modern classics

The Oris Artelier Calibre 400 is aimed at connoisseurs who want to combine classic style with modern sophistication. It's a dress watch that does more than just look good – behind its understated exterior lies one of the most innovative automatic movements in its class. Whether for work, travel, or formal occasions, this watch delivers reliable performance with timeless elegance.
