The "Chronometer" certification guarantees the high accuracy of a watch or a movement.

The tests run by the COSC include the verification of the engraved number on the watch movement and controls in a testing environment. Each movement is individually tested following a strict procedure that lasts several days in five positions and at different temperatures (8°C, 23°C and 38°C). Over 15 days, the movements go though daily controls. Every day - including Saturday and Sunday - the instruments are measured and wound. If it meets the standards, the movement is "Chronometer" certified.

Ceramic is a non-metallic mineral material that undergoes a specific treatment in a high-temperature environment. Many types of ceramics exist, each with their own unique properties suited to a variety of applications, from medicine to watchmaking. Ceramic is time-resistant, hypoallergenic and resistant to high temperatures, friction and abrasion. High-tech ceramics combine timeless elegance with distinct sophistication, belying their practically unmatched solidity. With the use of this material usually reserved for luxury watchmaking, MIDO confirms its constant desire to offer cutting-edge technology, the very best materials, and high-end finishes without forsaking the value of its watches.

MIDO’s sapphire crystal glass reveals its spectacular dials in sharp relief. They afford excellent readability in a range of conditions while perfectly complementing the watches' elegant design. Strong and shock-resistant, they are made to last, maintaining their exceptional transparency for many years.
