Catalog 15 of 1929 is the last catalog offered by the Chelsea Clock Company before the devastating stock market crash of September/Oct 1929. 12” and 10” striking clocks and special grand dials had already been eliminated from the line prior to this catalog. A review of this catalog shows that smaller clocks dominated the catalog and 8.5” striking clocks and 10” and 12” time only clocks were relegated to the end of the catalog. This catalog has a unique cut out cover showing the 8.5” Mariner (Yacht Wheel) Clock offered at $310 with special dial.
