The Ball Fireman Storm Chaser Pro was designed in collaboration with Dr. Joshua Wurman, a meteorologist and member of the Ball Explorers Club. It has a stainless steel case of 43 and either a black or grey dial. The bezel is engraved with a tachymeter scale, while the flange of the dial features an additional telemeter scale. It is powered by the Valjoux-derived RR1402 movement.
