Breitling watches are entirely manufactured in Switzerland, according to the strictest Swiss watchmaking quality standards. They undergo nearly 1000 checks during production, while all movements (mechanical and quartz alike) must successfully pass the extremely stringent tests of the Official Swiss Chronometer Testing Institute (COSC). Any manufacturing defect is covered by an international warranty, valid for two years from the date of purchase, or five years for watches equipped with a mechanical Manufacture movement.
The water resistance of a watch can only be guaranteed for a limited period of time, particularly due to the natural deterioration of the gaskets. It is therefore recommended to have the water resistance tested every two years.
The water resistance test can be performed by an authorized Breitling service center or retailer and is free of charge. Watches with a five year warranty need to undergo this test every two years, to keep up the coverage regarding water resistance problems and their consequences throughout the warranty period.
