A clock on Broadway was put up by them in 1930 near 1318 Broadway, and later moved to 1635 Broadway.
"Wonder why they didn't move it to Walnut Creek. Commissioned by Davidson & Licht Jewelry Co in 1930, the geometric structure containing the clock originally stood in front of the family-owned jewelry store a few blocks away at 1318 Broadway. Benjamin Davidson, a diamond broker and Arthur Licht, a watchmaker’s son, custom-built it to increase attention to their high-end jewelry business. In the first half of the 20th century, standing clocks served jewelry stores as red-and-white-striped poles served barber shops: announcing the store’s presence from afar. Between 1930 and 1947, the Davidson & Licht Jewelry Co moved twice, and took the clock with them, until they landed at 1635 Broadway." (from Oakland History group on Facebook)
