Engineered for serious divers and built to endure, the Citizen Promaster BN1024-01Z is a 46mm professional-grade dive watch that delivers on both performance and purpose. Its bold red dial stands out beneath a sapphire crystal with anti-reflective coating, while luminous hands and markers ensure visibility in the darkest depths. The stainless steel case is paired with a rugged black polyurethane strap for comfort and durability. Powered by Citizen’s Eco-Drive Calibre E365, it runs for up to 12 months on a single charge from any light source—no battery changes required. ISO-certified for scuba diving and water-resistant to 300 metres, it features a unidirectional bezel, screw-down crown, date display, and low charge indicator. This is a tool watch made for those who never back down from a challenge.
