Test the extremes with this CITIZEN Promaster Tough men's watch. Living up to its name, the timepiece features shock resistance and anti-magnetism. The 44mm stainless steel case and bracelet have CITIZEN's proprietary Duratect surface-hardening coating, which makes it 5X harder than stainless steel, in addition to rust-resistant, scratch-resistant, and hypo-allergenic. Other features include a light blue-gray dial, anti-reflective sapphire crystal, and super LumiNova hands and markers. The Caliber B612 watch features Eco-Drive technology, which is powered by any light so it never needs a battery. * LumiNova® is a registered trademark of NEMOTO and CO.,LTD.
