In addition, the Ross came in three different case materials, yellow gold filled, white gold filled and coral (rose) gold filled. Furthermore, different choices for hands and dials made selecting the right Ross even more of a challenge. In the end, there are at least six different varieties of Ross models to add to the watch stable.
One thing I find interesting about the Ross is for a 1930's model it really foretold a lot of the styling for Hamilton watches in the next 20 years. Considering it was discontinued in 1946, at least to my eye, it seems to fit in well with the rectangular watches that were introduced in the late 1940's and in to the 1950's.
It's a very sharp design and I especially like the gilt-dialed varieties.
