There are many styles in the Nautilus series but the dials are always round and they always had the 505 movement. Some were stainless steel (500), others in 10K Gold Filled (400), some in 14K solid gold (200) and others in 10K Rolled Gold Plate (600).

Sadly, many of the Nautilus stainless steel examples have been sacrificed over the years to become donor watches for the more collectible asymmetric and solid gold cased electrics.
