After 2016's Black Bay Bronze with a chocolate-brown dial and bezel, Tudor continues to explore this rare material with a new slate-grey dial—shaded from the exterior to the centre—and bezel as well as gold accents on the hands and hour markers. The high-performance aluminium-copper alloy used to manufacture the Black Bay Bronze model is hardy and durable and will produce a subtle, unique patina based on the wearer's habits. Its entirely satin-brushed finishes will also ensure a homogeneous development of the patina.
