The BOLDR Expedition Enigmath boasts a robust 41mm sandblasted stainless steel case, offering impressive resistance to both extreme temperatures and corrosion. The dial flaunts an elegant ombre gradient that darkens towards the edge, highlighting the white inner bezel that houses the slide rule. Luminous hour markers, along with the lumed hour and minute hands, ensure easy readability. Enhanced by an AR-coated sapphire crystal, the watch’s dial remains crystal-clear in all lighting conditions, adding to its practical and durable design for outdoor adventures.
