Notes:  This model is first seen in the advertisements (discovered to date) in 1926.  It shows in the 1926 ads as having both an engraved and a smooth, unengraved bezel.  The engraving on the Trojan is non-continuous, having a slight break at each corner.  In 1927, the Conqueror first appears in the ads.  The Conqueror case shape is the same as the Trojan, but the engraving is continuous around the bezel.  Also in 1927, the smooth, non-engraved bezel is renamed the Spartan.  By 1928, the Trojan is no longer seen, and the engraved Conqueror and smooth-bezel Spartan carry on this case shape.
