in p>24, initiated by Mr.

, four companies, Parma Johnny Watchmaking Factory, VaucherManufacture Fleurier Movement Factory, Chopard and Bovet, jointly formed a foundation called Fleurier Quality Foundation, and launched the QF seal, which originally had only four standards:

1. To obtain each watch with QF stamp, the movement you own must first pass the certification of COSC Observatory (ISO 3159 specification).

2. durability.

Watches have to pass a test called Chronofiable, which includes periodic handle operation test, anti-magnetic test, impact test (excluding complicated function table) and waterproof test. The number of watches tested is submitted in proportion to the number of watches produced. If the watch is produced within 1~1 pieces, 5 test numbers must be submitted; 11~2 pieces, you have to submit 1 test numbers; More than 21 pieces need to submit 2 test numbers.

3. Accuracy in actual wearing. Different from COSC, the table has to be put on the Fleuritest simulator for 24 hours of periodic oscillation test, and the data is recorded by computer; On the simulator that keeps moving, the watch must be kept within the error value of ~+5 seconds a day.

4. Technical and aesthetic requirements. Like the Geneva Seal, the decoration, polishing and material of the movement have certain specifications, such as prohibiting plastic parts and chamfering all parts; It must be assembled by hand or machinery, and it must not be assembled in bulk; Nickel plating is prohibited unless it is used for oxidation resistance of stainless steel. In 212, a new regulation was added to the original four specifications: 1% made in Switzerland; This provision is only for the meter head, and does not include the strap and buckle. Although any material source in the header can come from all directions, the processing of materials must be carried out locally in Switzerland; Of course, the tasks of assembly and fine processing have to be completed in Switzerland.
