When most people hear the name Oris, their minds immediately jump to rugged dive watches like the Aquis or the vintage inspired Divers Sixty-Five. But if you only look at their sports watches, you are missing out on some serious mechanical flexing. Enter the Oris Artelier Calibre 113, a watch that proves this independent Swiss brand knows exactly how to build a highly complex, executive-level timepiece without losing its pragmatic edge.

The Dial: A Masterclass in Organized Chaos

Packing this much information onto a watch dial is risky. But Oris managed to keep the Artelier Calibre 113 remarkably elegant and legible.

If you look at the outer perimeter of the dial, you will see the months of the year paired with weeks numbered 1 through 52.

The use of varied textures, like a smooth outer ring for the calendar and a recessed finish for the sub dials, creates depth and prevents the watch from feeling overly busy.

Calibre 113

The real star of the show is hidden right inside the name: Calibre 113. This is an in-house, hand-wound movement engineered by Oris that solves one of the biggest annoyances of manual watches, constantly running out of juice.

Thanks to a massive, single oversized mainspring barrel, the Calibre 113 packs an astounding 10 day (240 hour) power reserve.

Final Thoughts

The Oris Artelier Calibre 113 is a testament to what independent watchmaking can achieve when it prioritizes practical utility over sheer tradition. By combining an ultra-long power reserve with an incredibly intuitive business calendar, all adjustable via a single crown, Oris has created a mechanical tool watch disguised as an executive dress piece.

If you have the wrist to pull off the 43mm footprint, it remains one of the most compelling and uniquely capable calendar watches in its bracket.
