There are two ads published on Dec-06 and Dec 20, 1929 by Smit's Fifth Ave. Jewelers in the PITTSBURG PRESS, PITTSBURG, PENN.
The ad states: "flexible wristlet to match" meaning that the watch and bracelet was available in either synthetic sapphires or emeralds, both on the watch and wristlet/bracelet.
Here's another ad below. There is a difference in the size and shape of the dial minute track between the Miss Liberty and the Sylvette. See both watches below the ad.
Same watch as the other ad. The illustrator of the drawing has put an extreme emphasis on the "V" around the center stone.
This ad is from: DEC 14,1930 THE BALTIMORE SUN, BALTIMORE, MARYLAND from KAY JEWELRY COMPANY.
MY MISS LIBERTY 3rd version MY SYLVETTE
There is a difference in the size and shape of the dial minute track with these two watches. The Miss Liberty 3rd version VS The Sylette.
