Bell & Ross, a brand steeped in heritage, released two new models inspired by watches worn during the First World War. The WW1 wrist watch and the PW1 pocket are the world’s first Argentium silver watches. Argentium is a pure silver, oxidation resistant alloy. Dials are available in a silver or ruthenium finish with appliqué metal numerals with an alligator strap with an Argentium pin buckle.
