The Nivada Antarctic III
Heading text
The dress variation is one the very first spin-offs from the original Antarctic as may be seen in the advert of circa 1959/60 shown here. (courtesy of IG @nivadamuseum)
The very first variation is a steel case with straight plain capitalised text. This was closely followed by the wavy script as seen in steel and, rarely, gold cases. There is also a crosshair dial version.
The notable feature is the slim case and thin lugs as apposed to the flat top lugs of the first model. They are still waterproof with steel screw back cases as per other Antarctic and Aquamatic models of the time.
