Very rare version of the Nivada Antarctic from the 60s with an absolutely awesome dial- and casedesign. This  35mm (+crown) toolwatch has never been polished and comes with all original parts like signed crown and plexi. These watches were originally designed for the arctic expedition named „Operation Deep Freeze“ of Admiral Byrd and the US Navy in 1957/58. Nivada created  a waterproof and anti-magnetic automatic watch for them. Dial and handset are in awesome original condition. This rare watch will come on a new beige leatherstrap.
