The Citizen Promaster Tough Eco-Drive Men's Watch (Model CA0727-12E) is a rugged 44mm timepiece built for demanding conditions. Its black ion-plated stainless steel case features Citizen's proprietary Duratect surface hardening treatment, making it 5x harder than standard stainless steel with exceptional scratch resistance, anti-rust properties, anti-magnetism, and shock resistance.

Powered by Citizen's Eco-Drive technology, this watch runs on any light source and never needs a battery replacement. The movement is caliber B612. A scratch-resistant, anti-reflective sapphire crystal protects the black dial, which features Super LumiNova luminous hands and hour markers for excellent low-light readability. The watch offers a 1/5-second chronograph measuring up to 60 minutes, 12/24-hour time display, and a date window.

The camouflage-patterned strap is constructed from ballistic CORDURA® nylon and polyurethane for durability in the field. The watch carries a 22mm lug width and a buckle closure. Water resistance is rated to 200 meters (20 bar / 666 ft), making it suitable for swimming, showering, and snorkeling.
