Oris is a Swiss luxury watch manufacturer that has been in business for over 110 years. The company was founded in 1904 by Paul Cattin and Georges Christian in the town of Hölstein, Switzerland. 

Oris initially focused on producing pocket watches, but soon expanded into wristwatches as well. Throughout the 20th century, Oris continued to grow and innovate, introducing new models and technologies. In the 1930s, the company introduced its first automatic movement, and in the 1940s, it began producing chronograph watches. In the 1960s, Oris introduced its first diving watch, the Aquis, which was designed for professional divers. Today, Oris is known for its high-quality watches that are both functional and stylish. The company produces a wide range of models, including dress watches, sports watches, and diving watches. Some of the most popular Oris models include:

  • Oris Aquis: This is a diving watch that is water-resistant up to 300 meters. It features a stainless steel case, a unidirectional bezel, and a sapphire crystal.
  • Oris Big Crown: This is a classic pilot's watch that features a large, easy-to-read dial and a fluted crown for easy winding. It is available in a variety of styles, including a stainless steel case and a leather strap.
  • Oris Artelier: This is a dress watch that features a slim profile and a classic design. It is available with a variety of complications, including a date display and a moon phase indicator.
  • Oris Carlos Coste Limited Edition: This is a limited edition diving watch that is named after Carlos Coste, a world champion free diver. It features a titanium case and a helium escape valve.

Overall, Oris Watches are a great choice for anyone looking for a high-quality watch that combines functionality, durability and style. The brand has a rich history, and the company continues to innovate and produce watches that are designed to meet the needs of professional divers, pilots, and watch enthusiasts.

Frequently Asked Questions: Oris Heritage & Innovation

Q: Is Oris still an independent brand in 2026?

A: Yes. Oris has remained independent since a management buyout in 1982. This independence is the core of their identity, allowing them to pursue "Change for the Better" sustainability projects and develop the Calibre 400 without the pressure of corporate shareholders. In a 2026 market dominated by three major luxury groups, Oris remains one of the few "pure" Swiss independents left.

Q: Why is the "10-Year Service Interval" a big deal? A:

Most mechanical watches require servicing every 3 to 5 years to replace dried-out lubricants. The Oris Calibre 400 utilizes more than 30 non-ferrous and anti-magnetic components, including a silicon escape wheel and anchor. This high-tech construction, combined with specialized long-life lubricants, allows Oris to confidently recommend a 10-year service interval—effectively halving the long-term cost of ownership for the collector.

Q: What is the "Big Crown Pointer Date" and why is it so iconic?

A: First introduced in 1938, the Pointer Date is Oris’s longest-running signature. Instead of a standard date window, it uses a dedicated central hand that points to a date scale on the outer edge of the dial. This was originally designed for pilots who needed a large crown to adjust the watch while wearing gloves—a design feature that remains a favorite for 2026 enthusiasts who appreciate legible, tactile tools.

Q: How does Oris’s sustainability focus affect the quality of the watch?

A: It improves it. Oris is a Climate Neutral company, and many of their 2026 models feature technical innovations derived from sustainability. For example, their "Upcycle" dials are made from recycled PET plastic, meaning no two dials are exactly alike, while their collaboration with organizations like the Billion Oyster Project uses high-grade medical steel and recycled materials that are as robust as traditional counterparts.

Q: Is the Oris Aquis a "True" professional diver?

A: Absolutely. While the Aquis is known for its modern, "integrated" look, it is a tool watch at heart. The 2026 models feature a patented Extendable Security Folding Clasp and a ceramic bezel insert. When paired with the Calibre 400, it provides 300m of water resistance and a movement that won't be affected by the strong magnetic fields found in modern cockpit or engine room environments.
