Antarctic IV
=Early Date Model - Unsigned
With the same flat lug case and big crown as the first series, these contain an ETA with date dial and no Antarctic subtext. It is assumed that these were made before the US Navy 1957 DeepFreeze tour as Nivada certainly used the marketing coup associated with the expedition to its maximum on a huge variety of dials after this date. The same watch also appears with the Antarctic name in an advert.This movement is mostly associated with models circa 1950-1954,
