Strong and elegant, stylish and confident. The newly relaunched Citizen Series 8 mechanical collection of modern timepieces makes an unforgettable impression with sophisticated designs and advanced automatic movements. The richly detailed 831 mechanical timepiece features a superior accuracy of -10 to +20 per day in a luxurious, gold-tone stainless case and blue calfskin leather strap, a glossy blue dial with luminous hands and markers, and an anti-reflective sapphire crystal. This modern Citizen automatic men’s dress watch also features enhanced magnetic resistance to protect the movement against external magnetic fields, a 42-hour power reserve and water resistance to 100 meters. Caliber number 9051.
- Powered by the release of a wound spring, mechanical movements never require a battery. Automatic mechanical movements have an oscillating weight that winds the spring with the motion of the wearer’s arm.
