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.

MIDO watch movements combine all of watchmaking tradition's strict criteria. The models of most of the collections are equipped with a transparent case back showing the mechanical and aesthetic beauty of the Swiss watch movements. Our timepieces are endowed with an oscillating weight decorated with Geneva Stripes and MIDO logo, guilloché or circular-grained bridges, or blued screws. MIDO also offers a series of chronometers whose conformity is certified by a neutral testing bureau that provides an official certification after rigorous testing. Each chronograph watch is unique and identified by an engraved number on the movement.

MIDO exclusively uses high-grade 316L stainless steel for its steel components to ensure complete and continued compatibility with the skin. This material resists corrosion, is unaffected by magnetic fields and demonstrates excellent durability, making MIDO’s stainless steel watches enduring creations that can stand the test of time and weather the elements. The metal’s many technical properties are complemented by its sleek, extremely pleasing aesthetics, enabling a wide range of uses.

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.
