Found this ad in the Nov./Dec. 1958 issue of Swiss Horological Journal for the Titus  "Royal Time" Watch. The ad shows an automatic with 25 jewels (you really need only 17!), date, and sweep second hand.

Solvil (also known as Solvil & Titus) is a Swiss brand founded in 1887 in La Chaux-de-Fonds, Neuchâtel, Switzerland by Paul Ditisheim. Some vintage Titus watches are shown below:
