Antique A.G. Spalding Bros 15 Min Hourglass Sand Timer 520 Fifth Ave NY Cast Alu For Sale

Up for your consideration is an exceptionally rare, museum-quality antique 15-minute hourglass sand timer produced by the legendary A.G. Spalding & Bros. Standing at 6.5 inches tall by 3 inches wide [], this substantial desktop piece is an authentic relic of early 20th-century American luxury commerce. We know definitively that this piece is a genuine antique from the early 1900s due to the crisp, stamped maker’s mark on the heavy cast-aluminum base: "A.G. SPALDING & BROS. / 520 FIFTH AVENUE / NEW YORK." This specific address marks Spalding’s historic flagship retail location in Midtown Manhattan during the Gilded Age and Edwardian eras. At the turn of the 20th century, cast aluminum was considered a cutting-edge, semi-precious luxury material celebrated for its industrial elegance. Adding immensely to its rarity is the functional 15-minute countdown duration; while standard 3-minute and 5-minute timers are overwhelmingly common, a 15-minute sequence is incredibly difficult to find from this era. This is a premier crossover collectible combining prestigious New York retail history, early American manufacturing, and functional Edwardian desk decor that beautifully anchors any high-end office collection.
