Overview of COSC Certification
Getting certified by COSC is a great way to guarantee your timepiece is reliable and precise! The Contrôle Officiel Suisse des Chronomètres (COSC) is an independent, non-profit organization that sets the accreditation standards for Swiss-made timepieces.
Since 1973, it has been responsible for certifying chronometers—watches with precision accuracy—after they pass a series of tests. To receive certification from COSC, watches must go through an extensive certification process that includes 16 different days of testing at temperatures between 8° and 33° Celsius.
After passing these tests, the movement must display a daily variation rate no greater than +/- 6 seconds per day in order to be given the official COSC stamp of approval. This rigorous certification process ensures that all watches meeting the requirements are accurate to within -4/+6 seconds per day.
The testing process for COSC certification involves putting each watch through a battery of 15 individual tests over various positions and temperatures before being approved as a chronometer. Each test begins with manually winding the watch and then recording its performance during periods of 24 hours or more.
The results are measured against established norms based on international standards set forth by ISO 3159 regulations—the same guidelines used by many other countries around the world.
If any discrepancies occur during this testing phase, the watch will fail and not be given its COSC Certification until any issues have been corrected or replaced with new parts that meet their standards.
Once all tests have been passed successfully, the watch will receive its official COSC Certificate along with its unique serial number engraved onto its case back as proof of authenticity and accuracy.
As such, buyers can rest assured knowing that their Swiss-made timepiece has gone through one of the most rigorous inspection processes available in horology today – guaranteeing it will remain accurate no matter what conditions it may encounter in everyday wear.
With this peace of mind comes confidence knowing you’ve purchased a quality product backed by one of Switzerland’s oldest accrediting organizations – making it well worth investing in if you’re looking for something special to add to your collection!

Testing Process
COSC certification is based on internationally accepted standards of watchmaking, including criteria for precision and reliability.
Every individual movement is put through 15 days and nights of testing in 5 different positions at 3 different temperatures to ensure accuracy across the board. During this time, the watch must remain functioning within an acceptable range of timekeeping variation for it to pass the test.
In addition to this stringent testing process, each watch is further inspected by hand before being certified with a unique serial number that corresponds to its specific model.
The entire process usually takes around three weeks from start to finish and requires an immense amount of skill and experience on behalf of the manufacturers—all adding up to one thing: assurance that your watch will keep accurate time even when you’re miles away from home or deep underwater.
The thoroughness of the COSC Certification Testing Process ensures that any wristwatch sporting its seal has gone through extreme scrutiny so you know it will perform exactly as intended. This provides peace of mind no matter where your adventures take you or what kind of conditions you encounter along the way.
