We’re calling it. Bulgari has released the most important novelty of LVMH Watch Week 2025. While its fellow LVMH stablemates TAG Heuer, Zenith, and Hublot have iterated on their pre-existing releases this year, Bulgari has debuted an entirely new movement for LVMH Watch Week 2025.


When it comes to animalic associations in the jewellery world, none are more intertwined than Bulgari and the snake. With Bulgari’s history steeped in ancient Grecian and Roman tradition, it’s no wonder that the mythical allure of the serpent has long seduced the maison. The Serpenti line was originally inspired by the glamorous Roman jewellery worn by Cleopatra, but has since taken on a life of its own and is known for being a feminine, slightly suggestive icon in its own right.




With 2025 being the Year of the Snake in the Chinese calendar, Bulgari was perfectly poised to add new references to its Serpenti Seduttori and Serpenti Tubogas lines. However, Bulgari hasn’t simply slapped a few rubies onto the bezel, filed a press release about ‘hope and prosperity’, and called it a day. Instead, the maison has created a new automatic calibre specifically designed to inhabit the horological head of its iconic reptile.
Although the Serpenti was originally released as a mechanical timepiece in 1948, until now, contemporary Serpenti watches have used quartz movements (with the occasional manually wound limited-edition release) as no pre-existing automatic movement on the market adheres to the right size and weight specifications. With that in mind, the Bulgari BVS100 Lady Solotempo was developed entirely in-house and joins the Switzerland-based manufacture’s league of innovative movements which include the Piccolissimo (a tiny manually wound mechanical movement for jewellery watches) and the BVL150 (one of the smallest shaped manually wound tourbillon movements).




The BVS100 Lady Solotempo is an automatic, time-only (hours, minutes, and seconds) movement with a 50-hour power reserve. The movement measures a petite 19mm in diameter, has a thickness of 3.9mm, and weighs just 5 grams. True to its heritage as a jeweller, Bulgari has adorned the oscillating weight of the movement with seven Serpenti scales. The BVS100 Lady Solotempo was developed by Bulgari in its Le Sentier manufacture and will join the ranks of in-house movements available to other LVMH group maisons and will likely be manufactured by Zenith in its dedicated Movement Manufacture.


“Serpenti is more than an icon; it’s a signature,” Fabrizio Buonamassa Stigliani, executive director of watch design at Bulgari, rightly says. To celebrate its mechanical reinvention, Bulgari has released seven Serpenti Seduttori and two Serpenti Tubogas timepieces. Each newcomer is powered by the in-house automatic BVS100 Lady Solotempo.
All seven of the Serpenti Seduttori releases feature the same case proportions and dial layout. A 34mm case with a diamond-encrusted bezel plays host to a dial with elongated Arabic numerals, with the word ‘automatic’ featuring on the lower half. The Serpenti Seduttori arrives in two-tone steel-and-rose-gold with a white dial, steel with white dial, steel with black dial, yellow gold with full pavé diamonds, and white gold with full pavé diamonds. Meanwhile, the Serpenti Tubogas has a 35mm case and comes in rose gold, with the option for a single- or double-wrapped bracelet.




With its iconic case shape and elegant bracelet crafted from precisely cut hexagonal scales that wraps around the wrist like a second skin, its quartz movement is the only element that has let punters dismiss the Serpenti Seduttori as a mere ‘fashion watch’. Powered by Bulgari’s new automatic BVS100 Lady Solotempo movement, the Serpenti Seduttori and its sister, the Serpenti Tubogas, are set to enter a new era, cementing themselves as cultural and horological icons.
