The first erotic wristwatches were not wristwatches at all. In late-18th-century Geneva, master watchmakers like Pierre Jaquet-Droz, the Frères Rochat, and Henri Maillardet built pocket-watch automatons for the Ottoman court, the Qing dynasty, and the wealthier corners of European nobility. The watches typically featured a hand-painted enamel scene on the caseback (or sometimes inside a hidden compartment under a hinged cover), and a movement-driven cam triggered automaton figurines, who would, when the watch struck the hour or quarters, perform a discreet but unambiguous tableau. The genre was lucrative because export tariffs on overtly mechanical clocks were lower than on jewellery, and the hidden-erotic format gave a private buyer something to show only the audience he wanted to show it to.
The 18th- and 19th-century pocket-watch erotic automatons coming out of Geneva and La Chaux-de-Fonds were almost entirely export pieces for the Ottoman, Persian, and Chinese markets, where ornate decorative timepieces were prized at court and the social context for explicit imagery was different from contemporary Western Europe. The Forbidden City museum in Beijing and the Topkapi Palace museum in Istanbul both hold significant collections of Geneva-made pocket-watch automatons from this era. Western collectors did not really start buying erotic pocket watches at auction until the 1970s, when Antiquorum (Geneva) began catalogue-listing them with academic descriptions and discreet illustrations. Major examples now reach USD 200,000-500,000+ at auction depending on maker, complexity, and condition.

The modern revival of the erotic-watch genre is associated almost entirely with Ulysse Nardin under Rolf Schnyder, the entrepreneur who acquired the dormant Le Locle manufacture in 1983 and rebuilt it. Schnyder's creative collaborator Ludwig Oechslin developed the technical platform; Schnyder himself drove the explicit-imagery branding. The first commercially significant modern erotic was the Hourstriker Erotica: a sonnerie-passante minute-repeater wristwatch with painted-enamel automaton figurines visible through a dial aperture, who animate in time with the chime mechanism. Subsequent variants by Italian comic-book artist Milo Manara (the Classico Manara line, with Manara's signature line-art erotic illustrations on the dial) and various other limited editions extended the format through the 2000s and 2010s.
Blancpain has carried a parallel tradition of caseback engraving, often via the brand's Le Brassus haute-horlogerie atelier, in which a customer can commission a hand-engraved or hand-enamelled scene on the caseback of an existing reference (a Villeret moonphase, a Léman dress watch, etc.). Some of these caseback commissions have been overtly erotic, executed by the brand's in-house engravers, with the front of the watch remaining a perfectly ordinary dressed Blancpain dial. Auction examples of vintage Blancpain (and a handful of vintage Patek Philippe and Vacheron Constantin caseback erotics) appear at Geneva sales every few years, generally fetching multiples of the equivalent unstamped reference. The Métiers d'Art programme at Vacheron Constantin and the Hommage series at Audemars Piguet have included similar one-off engraving commissions, though typically with classical or mythological imagery rather than explicit content.
The modern Jaquet Droz brand (revived by Swatch Group in 2000, named after the 18th-century master) has continued the automaton-watch tradition with non-erotic content (singing birds, blooming flowers, miniature scenes), but the technical lineage runs directly back to the 18th-century erotic-automaton era. The contemporary luxury-watch market generally treats erotic watches as a small, specialist sub-category. Modern examples are produced in tiny limited editions (often 1-50 pieces), priced from approximately CHF 60,000 (Ulysse Nardin Classico Manara) to several hundred thousand francs (Hourstriker Erotica with minute repeater complication). Vintage erotic pocket watches sell almost exclusively at Antiquorum, Phillips, and Christie's Geneva, with the strongest market for the 1780s-1850s Geneva masters. The category remains discreet by design: the genre's defining aesthetic move is concealment, not display.
