Which one I'd pick
New vs pre-owned: with no grey-market discount today, $3,900 direct from Oris gets you the full 10-year warranty. A pre-owned one saves a lot, but check the warranty can be transferred.
What to check before you buy
- Warranty: the 10-year cover depends on MyOris registration. Ask whether a used watch's registration and warranty transfer to you.
- Ref check: Aquis models come in many sizes, dials and movements (including non-Calibre 400 ones). Match the full ref.
- Bracelet: check the clasp's quick-adjust works and all links are included.

History
Oris was founded in 1904 in Hölstein, Switzerland, where it's still based.
In 2020 Oris introduced the Calibre 400, its in-house automatic with a five-day power reserve and high resistance to magnetism.
The Aquis Date Calibre 400 was the first watch to carry it. Oris backs Calibre 400 watches with a 10-year warranty when you register with MyOris, and quotes 10-year service intervals.
