This exceptional Longines wristwatch, Ref. 4981724, is a historically significant piece dating back to 1931. Crafted in 18-carat yellow gold, it houses the revered manually wound Caliber 13.33Z, Longines’ first chronograph movement specifically designed for wristwatches. Known for its precision and robustness, the 13.33Z is celebrated among collectors for its classical architecture and smooth pusher action. The watch features a beautifully preserved enamel-style dial with Breguet numerals, blued steel hands, and a bi-compax layout with 30-minute counter and running seconds—hallmarks of early 20th-century chronograph design. Its round case and elegantly curved lugs exemplify the transitional style between pocket watches and early purpose-built wristwatches. Accompanied by an official Extract from the Archives issued by Longines on September 21, 2021, the document confirms the watch’s original delivery to the Spanish market on January 13, 1931. This piece is not just a fine mechanical chronograph, but a tangible link to the golden age of horology, offering rarity, craftsmanship, and historical value in equal measure. A true collector’s gem from one of Switzerland’s most storied manufactures. Ref. 4981724
