Additional variety was introduced by with Version 3. A move towards a more formal dress style saw thinner lugs and bezels and away from the original explorer concept. The crowns are unsigned and less substantial than the original scallop shape (which had first been seen on the original Aquamatics from the early 1950s).
Most dials have been observed with some marking- they are very prone to wear, damage and water ingress sadly. The unsmooth surface of the linen dial attracts dust and traps moisture. Pristine examples command a premium and will normally be NOS unworn. Another factor is the lacquer or varnish used on dials in this period by Nivada. It is prone to yellowing and discolouring as well as crazing, particularly if there has been any damp ingress, a distinct possibility with the non screwdown crown and a model marketed as waterproof. Very often a white dial (the Antartctic default dial colour) will appear at first glance to be cream or yellow. This can have a charm all its own - all dependent on the individual collectors eye for patina.
At some point around 1960 the font changed from a straight simple uppercase san serif to a stylised wavy written style for the word Antarctic. This is also seen in adverts at the time.
The automatic calibers are normally ETA movements with signed rotor and COW stamped on US models marketed by Croton.
