Oris began in 1904 when watchmakers Paul Cattin and Georges Christian purchased a factory in Hölstein, Switzerland. The brand grew into a major producer while remaining focused on practical mechanical watches. Today, independent Oris is especially popular for its Aquis dive watches, Big Crown pilot models, vintage-inspired Divers Sixty-Five collection, and innovative Calibre 400 movements with five-day power reserves.

Finding the right Oris watch parts can be tricky because bracelets, bezels, crowns, crystals, dials, and movement components are usually reference-specific. This guide covers estimated replacement-part prices, shopping tips, useful Oris manuals, and compatibility basics for popular collections such as the Aquis, Big Crown, Divers Sixty-Five, ProPilot, and Artelier.

A broken Oris can be frustrating, especially when your Aquis, Big Crown, Divers Sixty-Five, ProPilot, or Calibre 400 suddenly stops behaving normally. Luckily, many Oris problems can be diagnosed and repaired without replacing the entire watch. This guide covers common Oris faults, repair costs, official service options, maintenance tips, and what to know before buying a broken Oris for restoration.

Trying to find an Oris service center or authorized dealer nearby? Whether your Aquis needs a water-resistance check, your Big Crown is running slow, or you simply want to buy a new Oris from an approved retailer, this guide shows you where to look, what to expect, and how to find official Oris service and dealer locations around the world.

Buying a pre-owned Oris can be a great way to get an Aquis, Divers Sixty-Five, Big Crown, ProPilot, or older vintage model for less than retail. eBay has plenty to choose from, but picking the right seller matters. Below are established sellers to check, practical buying tips, and a few solid alternatives for used Oris watches.
