A seventeenth century watch, thin as a half dolar, and a nineteenth century chronometer, souvenir of the marriage of Queen Victoria and Prince Albert, will be shown at Wiss Sons, Inc., jewelry store, 665 Broad street, starting Monday. The exhibition, open to the public, will include 73 antique watches, some dating back to the early 1500s. One is in the form of a beetle, with diamonds. The display was loaned by Louis Aisenstein, New York importer.
