Robust, sporty and sleek

Yet also refined, intriguing, sophisticated: the new ARMURE MU03 is a world of its own. Equipped with nO-Ring® mechanical direct-seal gasket-free water-tightness technology, the latest addition to MAURON MUSY is not only water-resistant to 300m, but also splash-proof and easy to handle under water.

An avant-garde partner ideal for all settings, including the most hostile environments. Entirely attired in anti-allergenic titanium, immediately recognisable by its industrial design and brushed finishes, it is just as well teamed with adventurers’ gear as with an evening outfit. This intrinsically noble model houses an exclusive Manufacture movement. The ARMURE MU03 is undoubtedly the first watch with a maintenance-free five-year guarantee.
