The first La Sallita was a 2 inch time-only clock with ring on top and two legs. The style 2 La Sallita had a rectangular ivory or black Bakelite® case. Style 3 had a metal cushion shaped case and had an alarm. Style 4 was part of the boutique line with a solid brass case and automatic alarm.
When identifying a LaSallita style, observe the case shape and ignore the case and dial color, as some styles were made in various case and dial colors, as shown in the detail page for each style.
The Western Clock Mfg. Co. was granted a trademark for LA SALLITA on April 24, 1906. The registration contains the statement "The trade-mark has been continuously used in the business of said corporation since the 1st day of January, 1895."
