In 1886, the Geneva government promulgated the "Geneva Seal" law to prevent the identification of pirates in Geneva from being abused by using "Geneva Seal" engraved with "Eagle and Key" motifs on the movement as the locus of origin of the motive. (Source: Time to spread) In 2009, the Geneva Timepieces and Microengineering Laboratory (Timelab) began to operate the "Geneva Seal" project. Timelab is a private foundation chaired by a nine-member board of six government delegates from the state of Geneva in the fields of education, economics and finance, three representatives from the Geneva watch industry and the government of the state of Geneva ensuring Timelab Neutrality and independence. "Geneva Seal" law In 2011, which is also the 125th anniversary of the "Geneva Seal", the "Seal of Geneva" has been greatly modified following the 12-year-long centripetal component 12-rule of certification. The new rule consists of three parts technically. The first part follows the old 12th rule and is classified into nine parts in the new version. The parts are molded parts, reeds and lever springs, splints, gem bearings, gear trains, escapements, adjusting mechanisms, speed control systems, etc. Core components of the material, size and chamfer, grinding and polishing and other finishing to make detailed specifications. Added Part 2 on finishing criteria for chamfering, sanding and polishing of casing components including watch cases, straps and buttons. The new Part 3 on the performance of the watch (header), including waterproof performance of not less than 3 bar; 7 days walk deviation of not more than 1 minute; power storage not less than the published value. dispute A certified header provided by a certified applicant includes a movement component and a set of drawings. Timelab issues a certification report through a two-week audit and thereafter periodically reviews applicants' watch movement, component stock and movement assembly To ensure that the batch of products meet the standards of certified boards. The above is the mark of the specific certification process. As a result, one of the controversies is that non-100% certification marks the heart by one. The second of the controversies comes from the historical origins of the Geneva mark, its strong geographical protection and many of the brands that missed the mark simply because they are not engaged in watchmaking in the Geneva area, but they also possess state-of-the-art manufacturing processes and technology, As a result, the authority and value of the mark have also been weakened and questioned. Related watch brands Patek Philippe used to be the most powerful supporter of the Geneva imprint, but in 2009, Patek Philippe announced the renunciation of the use of the Geneva Seal instead of developing its own Patek Philippe imprint, the official reason is that the Geneva Seal impracticably satisfies Patek Philippe in terms of specific rules and enforcement processes high standard. Possibly the reason for this is that Patek Philippe in Vaud and Neuchâtel , outside of Geneva, the new factory, so we can only discard the Geneva Seal. These two possible reasons also point to the controversy we mentioned above. Vacheron Constantin ( Vacheron Constantin ) became the Geneva Seal is currently the biggest fans. Watch upstart Luo Jiedu He (Roger Dubuis) is declared across the board watches through Geneva Seal certification.
