This elegant chronograph is clearly aimed at lovers of beautiful timekeeping instruments. In stabilised CuAl7Si2 bronze (91% copper, 7% aluminium and 2% silicon), its 41-mm case stands out with its distinctive yellow gold colour. Known for its changing nature that gives it its unique character, bronze – a material cherished by Bell & Ross – provides a whole palette of unique shades. Although stabilised, the material changes over time - as if by magic!
