+ | The principle of the bayonet compressor used here was rediscovered by Martin Klocke while studying old archives. It concerns both the crown seal and the caseback seal. First, the history of this invention: | ||
+ | |||
+ | * **Crown seal:**\\ The ingenious idea is to do without the [[screw-down crown]], but to use the rising water pressure for sealing. This technology, called Monoflex, was developed in the 1950s by Ervin Piquerez S.A. ([[EPSA]]) and updated by Sherpa. \\ In this process, higher external pressure leads to pressure on the seal towards the tube, while the pressure decreases or disappears at lower (or no) pressure. The sealing materials used here are not common in the watch industry and are very long lasting and resistant agains wear. | ||

+ | This term refers to a design idea that has never been seen before in this form: Similar to Tibetan prayer flags and prayer wheels, which mechanically carry spiritual messages to the world, here watch wheels are engraved with laser-engraved texts in microscopically small original letters, spreading "good vibrations" | ||
