Hi Kathy, I am happy you don't have my book yet because it would have spoiled the fun of your research LOL! It will come out on 28 October to celebrate the 100th anniversary of their first Saturday Evening Post ad and contains 5 pages explaining the Lucille Luella story. The key question is "what watch was the model used for the illustration?". That turns out to be a solid gold Lucille of 1925 (!). Novelty was not a reason to advertise a watch! The models existed already for some time before they made it to an ad. This changed in 1929 with the introduction of the Miss Liberty that was introduced using an ad. The 1926 edition of the Lucille received the extra engraving but Bulova did not bother to update the illustration (as they didn't bother doing so for many other models!). That only happened in 1929, the reason being that they had introduced the filigree bracelet as a standard on solid gold and gold-filled models, so they had to update all their illustrations and in the process they updated the engraving to the reality. As you indicate, in 1928 there was a name change to Luella, one of the many name changes that happened. Some models changed name 5 times! Unclear why. One question to you: I did NOT find a 1927 Luella ad, only 1928 versions. So, this ad above you say is a Luella ad of 1927, can you give me some detail so I can find it?
