|About nO-Ring® Technology

Eric Mauron and Christoph Musie, the founders of MAURON MUSY, have invented a new waterproof technology nO-Ring® system that does not use packing or gaskets at all, based on years of experience as engineers. Did. Until now, the waterproof system of wristwatches has been done by gaskets (packings). However, since the gasket (packing) is made of a synthetic material, it has a limited life and needs to be replaced regularly to keep it waterproof. MAURON MUSY's nO-Ring® technology realizes a 100% waterproof wrist watch with ultra-high precision mechanics, which does not have the restriction of regular gasket replacement. nO-Ring® technology combines three principles: mechanical sealing technology, clamp braces, and satellite compression springs. Its excellence lies in the fact that this device has been miniaturized and adapted for the production of watches.

MAURON MUSY was founded in 2012 in Switzerland by Eric Moron and Christoph Musie. After more than 20 years of experience in the watch industry under a leading brand and a long research period, they have invented a new waterproof technology nO-Ring system that does not use packing or gaskets and have obtained a patent. At present, in addition to being equipped with the world's only waterproof mechanism nO-Ring system that does not deteriorate due to parts, in the lineup after Mμ03, the brand's first self-made automatic movement (CalibreMM01) is installed. .. MAURON MUSY watches do not have the "SWISS MADE" stamp, but instead 100% of the watches were developed, manufactured and assembled in Switzerland and are proud of the "SWISS CRAFTED" label. I am thinking.
