Mauron Musy offers a breakthrough timepiece in ultra-tough industrial bronze featuring a
patina designed to last forever, offset by the linearity of wholly modern khaki etching.

Equipped with nO-Ring® seamless mechanical sealing technology, the latest from MAURON MUSY is not only airtight up to 300m, but is also splash-resistant and can be handled underwater. This model houses an exclusive manufacture movement and is instantly recognisable with its industrial design and brushed finishes.


Mauron Musy, a family-owned brand rooted in the Broye Valley of Switzerland, is characterised by its rich industrial design and mechanical technology heritage. Guided by a philosophy that emphasises both the external intricacies of timepieces and Swiss craftsmanship, the brand distinguishes itself through the innovation of the inaugural mechanical direct-seal gasket-free water-tightness technology mechanical sealing system. Notably, Mauron Musy timepieces are not stamped with the conventional 'Swiss made' designation but proudly showcase the 'Swiss Crafted' label. This certification attests that every aspect of the watch, from development to manufacturing and crafting, is executed entirely within Switzerland.
