he rise of the wristwatch was unstoppable, punctuated by events that bolstered its image and cemented its success. The Swiss Fair in Geneva (1920), the Paris Exhibition (1925 – famously known as the birthplace of the Art Deco style), and the Universal Exhibition in Barcelona (1929) celebrated the fusion of technology and jewellery, consolidating the appreciation of the female audience.
Athletes, explorers, aviators, and show business stars wore their timepieces as they engaged in a variety of activities, all of which garnered media attention. Watch brands recognised that associating their products with contemporary heroes offered a significant advantage in capturing the male market, and advertising played a crucial role. Longines associated itself with aviation records, Rolex launched the Oyster by pairing it with swimmer Mercedes Gleitze, and several manufacturers capitalised on the success of sports competitions to promote their chronographs.
At the same time, watch technology broke new ground, and advertising campaigns highlighted these innovations. LeCoultre, Harwood and Glycine introduced the first two-level movement, the first automatic wristwatch and the first with the Geneva Seal, respectively. Most advertisements showcased rectangular and square-shaped cases, which, in the eyes of customers, had the merit of emphasising the distinction with the typically round pocket watch. The latter’s presence in advertisements diminished significantly, as it became clear to everyone that the future belonged to the wristwatch.
