We work with two independent outside companies for quality control.
Inspection is carried out on each production batch based on the system used in the watch market. Inspections are never carried out repeatedly by the same inspectors.
Standards are stricter than those generally used in the watch market, i.e. AQL (Acceptable Quality Level) Level 3 with Major 1.0 and Minor 2.5.
What is the AQL system?
This system defines the maximum number of defective parts a batch can contain to be accepted. If the number of defective parts found during an inspection is greater, the entire batch is rejected.
Inspections are carried out on each batch before they are sent to our logistics centre. A sample is taken from each batch. Sample size is determined by AQL system level 3 and the method for taking the sample is based on international quality control standards. (MIL-STD-105E, ANSI/ASQC Z1.4, ABC-STD-105, BS6001, ISO 2859, DIN 40080)
The inspection is carried out in 3 phases:
1. On exiting the assembly line: all of the watch’s mechanical functions, its water resistance and its esthetic appearance (scratches, scrapes, etc.) are checked.
2. During the packaging phase: verification that the watch is properly packaged, that the warranty is in the box, etc.
3. During the packing-for-shipment phase: checking of cardboard boxes and assurance that they are properly closed.
