So, how can you rest assured that you're getting a watch of exceptional value? That's where COSC certification comes in.

What is COSC Certification?

COSC stands for Contrôle Officiel Suisse des Chronomètres. It's a Swiss non-profit organization that aims to preserve the reputation of Swiss-made timepieces. Any brand can say that it has Swiss watches. But if you're looking to invest in a watch with the signature Swiss quality, you need to look for COSC certification.

This organization is independent of watchmakers. They're impartial judges who rigorously test time-keeping components. COSC has strict standards, and only the finest materials and construction techniques fit the bill.

If a watch meets the organization's standards, it receives a certification number on the movement. Not only that, but an official paper certification will come with the purchase.

How Common is COSC Certification?

More than a million watches get COSC certification every year. That might sound like a lot, but it's not compared to the bigger picture of the Swiss watch market. On average, only about six percent of Swiss-made watches receive certification.

Swiss watch making is already renowned around the world. COSC certification is a step above the rest, signifying exceptional quality beyond the norm.

What Brands Have COSC Certification?

It's important to remember that certification goes to individual watches, not entire brands or small collections. That said, some brands have refined their engineering so much that COSC certification is widespread.

This won't surprise any watch collector, but Rolex typically receives the most certifications every year. Omega follows as a close second. Other brands that often receive a certificate include Breitling, Tissot, Longines, and more.

Peace of Mind

When you buy used Rolex watches, look for that COSC certification of approval. It provides instant peace of mind, ensuring that you're getting the impeccable quality the brand used to build its global reputation.
