Longines Diamonds Cocktail Watch, 1920s–1930s

Dealer description — Analog/Shift

There’s a very particular kind of glamour that only exists in the Art Deco era — the kind that feels equal parts jazz club, cigarette case, and midnight cab ride. This vintage Longines cocktail watch captures that mood perfectly, with a tonneau-shaped case that leans into Deco geometry without feeling fussy or precious. Longines is a brand that needs no introduction. It was a staple of the Swiss watchmaking industry throughout the 20th century. They are well-known for their broad assortment of models and designs, as well as their masterful — and iconic — chronographs. Today’s piece is a wonderful extension of their watchmaking prowess into the realm of delicate ladies’ watches. Dating to the 1920s–1930s, it features a petite tonneau (tortoise or barrel-shaped) case set in a pale precious metal, typical of the era, with a shimmering field of brilliant-cut diamonds framing the dial. Bold 'Arabic' numerals encircle the design in blue sapphires, creating that signature Deco contrast, while the center remains elegantly restrained: a warm silver-toned dial signed Longines, finished with a crisp minute track. Topping it all off is a blued steel 'spear' handset. Inside, the watch is powered by a manual-winding mechanical movement, exactly as a proper ladies’ dress piece of the period should be. The case is engraved on the sides and back, and it comes fitted to a simple black leather strap with a traditional pin buckle, letting the watch itself do all the talking. This is the exact category that’s been quietly resurging lately: true vintage ladies’ pieces worn not as “women’s watches,” but as pure style. Jennifer Lawrence, a long-time Longines Ambassador, has been championing this look on the red carpet (including at the 2026 Golden Globes), proving that the most modern watch statement you can make right now is sometimes the one that’s already stood the test of time. Over a century, in fact!
