The Vulcain Cricket is an iconic Swiss watch, celebrated as the first true mechanical alarm wristwatch, introduced in 1947. Known for its distinctive and powerful alarm sound—often compared to a cricket’s chirp—the Cricket quickly gained popularity among professionals and became known as the "President's Watch," with several U.S. presidents, including Harry Truman and Lyndon B. Johnson, known to wear it. Its robust design and reliable alarm function made it a favorite among explorers and aviators as well. Today, the Vulcain Cricket is cherished by collectors for its historical significance, innovative alarm feature.
