World Watch Day
Faithful to its mission of precision and excellence, the COSC is taking part in the World Watch Day this October 10th at exactly 10:10 a.m, a symbolic time for watch enthusiasts around the world.

Advocating for Swiss Made
We only certify Swiss Made movements and watches. In doing so, we uphold our commitment as a non-profit public interest association: to celebrate and promote Swiss watchmaking expertise worldwide.
We work closely with the most prestigious Swiss watch brands, renowned for their unique expertise and pursuit of excellence. By committing themselves to the highly demanding COSC certification process, these manufactures demonstrate their commitment to delivering timepieces of the highest quality to their customers. This certification serves as both a mark of recognition and a guarantor of excellence for future buyers.
Watchmaking federations, associations, schools, and research centers—since its founding, the COSC has worked hand in hand with all the key players shaping Swiss watchmaking excellence.
