In 1675, the Dutch scientist Christiaan Huygens invented the construction of the combined elements of the balance wheel and balancing spring, thus inventing the basic clockwork (mechanical) catch. If you look now at your wrist, there is a very good chance that your watch works exactly the same, age-old solution. Refined, of course, in line with today’s standards and possibilities, but in principle faithful to Huygens’ invention.
The classic layout is built on an average of 30 elements, it has more or less Smm height. It also requires precise assembly and manual adjustment. Zenith’s invention – in no way resembling a traditional oscillator (see above) – is a monolithic, one whole, made of a special kind of monocrystalline silicon coated with silicon oxide. The finished element has only G.Smm thick and all the advantages of the metal with the chemical symbol Si: no need for lubrication, resistance to magnetic fields and extreme temperature variations and high strength. I do not even mention the extremely simplified assembly and adjustment, but the precision is the most important. Mounted in the ZO 342 caliber, the oscillator operates at the frequency of lSHz (3 times as much as the El Primero iconic), that is 108,000 A / h, with an amplitude of +/- 6 degrees. Daily deviation does not exceed 0.3s – that is, as much as in the average quartz watch. The mechanism has 6oh of energy reserve, and its almost ideal walk will fit 95% of this value, losing a bit until the very end of the “unloading” of the automatically winded spring. For comparison, the standard caliber loses accuracy after just 24 hours, and the COSC chronometer certificate is considered precise by the watch whose deviation is within the range of -4 / + 6s per day. In this light, Zenith’s achievement in itself makes an impressive impression.
This is confirmed by the “head of the viper” – emblem of the certificate of the Besancon Observatory. Resembling metallic foam material is the lightest form of aluminum used in watches, almost three times lighter than titanium and twice from ordinary aluminum. It is created in combination with a special polymer that fills the pores in the aluminum structure resulting from processing in the mold. Ten copies of Defy Lab will be leaving for the start with Le Locle – each one unique by the application color on the skeleton face. Everyone in a special set with a visit to the factory and other bonuses worth publishing 29.90oCHF. Ten volunteers found out faster than the information about the watch was made public. Fortunately, it seems that Defy Lab is not one of those conceptual creations that are dying before they were born for good.
