The automatic mechanical movement independently developed and manufactured by Emile Chouriet was certified by the Official Swiss Chronometer Testing Institute (COSC) in 2017. With a diameter of 8¾''' and long power reserve, it consists of 137 components, constructed with a precision escapement mechanism and a balance wheel and hairspring system that showcases the beauty of its mechanics in every detail.
The creation of an in-house watch movement and the use of new materials demonstrate Emile Chouriet's commitment to the field of watchmaking and its aspiration to become a fully independent watchmaking brand. By deciding to produce its own movement and developing special components, like the hairspring, during the manufacturing process, Emile Chouriet has taken a monumental step towards its goal.
Emile Chouriet is now among the few brands that are able to independently produce such components. The introduction of the in-house movement inaugurates a new era in Emile Chouriet's manufacturing and opens up endless possibilities for the company.
Emile Chouriet made the decision to first use its in-house movement in women's watches.
When designing the movement, the brand's watchmaking team made countless revisions to achieve the ideal curve and find the perfect balance.
The rounded movement embodies elegance, harmony and femininity in motion. Feminine qualities inspire Emile Chouriet's watch design, and the brand's timepieces are poetic in their precision.
Some of the important components of a watch movement are the balance wheel and hairspring module.
As fine as a human hair, the hairspring is connected to the balance wheel, which produces vibrations.
Adjusting the hairspring is a rather complicated and sophisticated process. This is precisely because few watch manufacturers produce their own balance wheels and hairspring modules. When the balance wheel and hairspring begin to run, they resemble a heart, and this is where its wonder can be found.
Despite the advancement of science and technology, the structure of the balance wheel and hairspring module has changed very little since it was conceived by Christiaan Huygen, a Dutch mathematician and scientist, in the 17th century.
Thus, the craftsman at Emile Chouriet had to meticulously hone their skills to craft the 4 Hz vibrating balance wheel and hairspring module. This makes Emile Chouriet one of the rare watchmakers who produce their own balance wheels and hairsprings.
Every in-house movement prototype must undergo stringent testing by independent laboratories to ensure the highest quality standards.
Meanwhile, the in-house movement that is the pride of Emile Chouriet has also been tested in real-life conditions to verify its accuracy and durability.
The brand is also preparing to introduce newly designed movements and complex components, primarily for use in men's watches.
Emile Chouriet has developed its own hairspring.
Emile Chouriet possesses its own design patent.
The three exceptionally beautiful curves on the balance wheel's hub are clearly visible.
After the hairspring is drawn out, coiled, shaped, cut to length, and assembled on its central piece, the balance wheel is pressed, refined, and adjusted for dynamic and static balance. Then, the two are assembled together with double disks, collet, and outer stud, ultimately coming together to form a complete balance spring module.
COSC inspects 1.8 million mechanical and quartz movements each year. COSC is the only organization in the world that is capable of testing such a large volume of watches. Each certified watch is unique, with a code engraved on the movement as well as a code issued by COSC.
Emile Chouriet's EC5318's high-class movement earned the COSC certification in 2017.
