Mauron Musy

Mauron Musy was founded in 2013 by Eric Mauron and his son-in-law Christophe Musy in Switzerland's Broye Valley, where Eric had long run a mechanics workshop supplying components to the watch industry. The pair developed nO-Ring, a patented mechanical sealing system that makes watches water resistant without a synthetic gasket.

Mauron Musy controls its process from design through final assembly, producing components locally under the Swiss Crafted standard. Manfredi Jewels is an Authorized Mauron Musy Dealer. Shop Mauron Musy watches at Manfredi Jewels Greenwich CT Location.
