Watch 101: Quality Standards

 

DEFINE: Rigorous tests completed on watches to ensure strict quality criteria are met and to distinguish watches made from the highest standards.

 

COSC (Controle Officiel Suisse des Chronometres): The COSC is currently viewed as the industry standard for movement accuracy and tests only the accuracy of non-cased movements, tolerating only the slightest (small) deviations for mechanical movements.

 

Geneva Seal: The seal is reserved for watches made in Canton of Geneva; it defines high quality standards for the manufacturing and finishing and decoration of the movement, with some specifications on technical design (water resistance, power-reserve, the rate, etc.…).

 

Fleurier Quality Foundation: To receive the certification the watch must be manufactured in Switzerland along with strict stages of finish for each watch.

  • Product Development: The Fleurier Quality Foundation validates the qualities of the finishes.
  • Technical Design: Tested with a Chronofiable Test, see below.
  • Manufacturing: The watches must pass the COSC and Fleuritest trials.

 

METAS & Master Chronometer (Omega): To achieve this standard, the watch needs to be COSC certified and be able to pass tests that replicate real-life wearing conditions and demonstrate resistance to water and magnetic fields.

 

Chronofiable Certification: Chronofiable Certification focuses on durability and reliability of watches, simulating several months of wear and tear.

 

Independent brands testing standards includes:

  • Patek Philippe Seal
  • Jaeger-Lecoultre 1000 Hours
  • Montblanc 500 Hours
