Bulgari Serpenti: A Guide to the Iconic Snake Watch Design

Across human history, the snake, or the serpent, has become one of the most enduring and evocative symbols for our kind. In the watch world, the Bulgari Serpenti has successfully transformed that ubiquitous mythical symbol into one of the most iconic jewelry-watch designs of all time. The Italian luxury house produced the first Serpenti in the late 1940s, and it has been a resident of the Bulgari universe ever since. The collection has, quite obviously, undergone much change since its introduction 78 years ago. In the guide below, I’ll be honoring my enduring love and affection for the Bulgari Serpenti, taking you on a journey from the first models to the collection's evolution to fit today’s watchmaking landscape.

The serpent has captured our imagination since the dawn of storytelling, and is subject to a myriad of symbolic interpretations across cultures and time. In the biblical context, the serpent functions as the ultimate source of temptation and manipulation, ultimately causing Adam and Eve to be thrown out of the Garden of Eden. For the Greeks, the caduceus, or the snake-wrapped staff carried by the Greek god of medicine, Asclepius, represents healing, and is still used today in the medical sphere. Further, Medusa’s snake hair could be interpreted as a symbol of danger and dread, but also, paradoxically, one of protection, as statues of the Gorgon’s head were often placed in front of temples or on shields and armor. For the ancient Egyptians, the uraeus cobra evoked royal authority, while the ouroboros symbol of a snake devouring its own tail encompasses eternity and the endless cycle of time. In the mid-20th century, Bulgari would make the serpent its own, recognizing its richness and transforming the snake into a motif for continuous innovation, daring, and exploration.

In 1948, Bulgari was still best known as a Roman jeweler, particularly esteemed for its goldsmithing and its use of classical Roman motifs. During Italy’s post-World War II recovery, Rome was emerging as the country’s epicenter of art, fashion, and culture, and Bulgari began moving away from its more traditional, Art Deco designs into the more experimental and bold savoir-faire for which it would become synonymous. With its 1948 launch, the first Bulgari Serpenti watches would represent the next era of style for the brand, and serve as a blueprint for where it would go next.

The initial Serpenti models introduced during the late 1940s didn’t get their name from featuring an actual sculpted snake head for the watch components like we know and love today, but rather, for their coiled, wrapping, “Tubogas” bracelet. Originally inspired by the shape of gas carrier pipes of the era, Bulgari began making the Tubogas bracelet styles in the 1920s, and the technique produced a flexible, malleable band with rounded contours that did not need hours of soldering work to make. Through the 1950s, many Serpenti models featured the combination of the Tubogas bracelet with a geometric dial, typically in square, rectangular, and circular shapes.

In the mid-1950s, Bulgari began experimenting with making the serpentine motif more literal. This is the era when the Serpenti officially becomes a "snake watch" in the most obvious sense. It is where you see the brand fully lean into drama and boldness, hiding the dial in a hinged snake head. The wrapping Tubogas bracelet became adorned with enameled snake scales. Precious gemstones were used, either set all along the snake’s head for high-jewelry models, or simply for gemstone (most often emerald or ruby) eyes. 

While filming the 1962 Cleopatra film, Elizabeth Taylor was photographed wearing her own high-jewelry Serpenti watch on set (a gold model with a lavish, diamond-set head model, to be precise), which helped propel Bulgari into the limelight.

The 1960s are often considered the Serpenti’s Golden Age, when many of its defining principles were codified. Throughout the 1970s, the brand’s resident snake watch underwent pretty dramatic experimentation. In addition to the porcelain, and realistic "hidden watch" takes on the line, Bulgari began experimenting with combining the serpentine-wrapping Tubogas bracelet with geometrical cases and different dial combinations, almost riffing off of the less obviously snake-like renditions of the line’s earliest era. Throughout the decade, we see octagonal and dramatic teardrop cases enter the fold; snake-print mesh-style takes on the wrapping bracelet; and more ruggedly minimal, index-free dials were all fair game. Reflecting the style of the era, these designs were bold, dramatic, and explicitly glamorous. Importantly, it was during the '70s that Bulgari began to embrace the advent of quartz movements for the Serpenti line, as the previously used miniature mechanical movements (often sourced from Jaeger-LeCoultre, Vacheron Constantin, and Audemars Piguet) were being produced in fewer numbers. 

The stylistic evolution of the Bulgari Serpenti continued throughout the 1980s, and, of course, adapted to reflect the maximalism that defined the era. This is where we see Bulgari really lean into incorporating the Roman-coin case motif that defined another one of the brand’s icons – the Gérald Genta-designed BVLGARI BVLGARI (released in 1977). Further, we see the brand move away from serpentine realism (though that take on the motif would never leave the catalog entirely). Opulence was the defining principle of this moment in the Serpenti’s timeline, from larger, more brash proportions to even more blinged-out models with precious gemstones. 

All-steel 90s Bulgari Bulgari Serpenti

As the fashion world evolved to focus more on refined minimalism in the 1990s, so, too, did the Bulgari Serpenti. Representative of where the line was going, the Serpenti of the '90s continued to move away from snakey hyper-realism, focusing on sleekness, and Bulgari launched some of the most understated models during this time. By the tail end of the 1990s, the Serpenti was in a transitional period, growing out of its current skin, and getting ready to slough off the old in favor of a new contemporary identity with the turn of the century. 

After a bit of hibernation in the early aughts, the Serpenti would relaunch with full force in 2010. This kicked off the year prior, as the brand was celebrating its 125th anniversary. Bulgari laid the foundation for the Serpenti’s next chapter with the Serpenti Scaglie (which the brand now refers to simply as the “Serpenti Jewelry Watch”) — a daring, explicitly high-jewelry-oriented design that opted for individual, scale-shaped links over the signature Tubogas bracelet. As the story goes, Elizabeth Taylor herself was gifted with a double-wrapped, pink-gold edition. The following year, the brand unleashed the Serpenti Tubogas, effectively creating the blueprint for the Serpenti’s modern identity. This is where we see the smooth, snake-head case and integrated Tubogas bracelet combination in full force. 

From 2010 on, the Bulgari Serpenti has been basking in the favorable rays of continuous success and has undoubtedly become a modern icon of the watchmaking world, particularly in the category of ladies' watches. The line has been riffed on, expanded on, and refined, offering distinct model families with renditions in a varying array of materials from steel to ceramic and just about every flavor of gold you can imagine. Its perennial popularity lies not only in its deep historical roots but in the way the brand has modernized the design for the modern watch wearer, offering options from the understated to maximalist luxury. Of course, much of the strength of the Serpenti is derived from the symbol of the snake itself, which evokes a sense of power and transformation, and a thrilling touch of danger. 

One of the most impactful upgrades in recent years for not only the Serpenti, but for the teeny-tiny watch genre writ large came with the 2025 debut of the Lady Solotempo automatic movement. Initially launching within nine models across the Serpenti Tubogas and Serpenti Sedutori collections (more on the specifics of those lines down below), the manufacture BVS100 Lady Solotempo Automatic Caliber is one of the smallest mechanical automatic movements available on the contemporary market. For tiny-watch lovers in the post-quartz world, this was (and still is) huge. 

Because achieving the necessary mechanical complexity of teensy movements is an incredibly difficult task, many watchmakers gave up the effort almost entirely once quartz came along. But, with the women’s collecting community only growing stronger, and demand for small and internally sophisticated watches along with it, the impact of Bulgari pulling up its proverbial bootstraps and creating a new, pint-sized automatic caliber for the 21st century is a sign that we might have a small-watch renaissance on our hands. To give you a sense of the scale, the BVS100 Lady Solotempo Caliber measures just 19mm in diameter and 3.90mm thick. It’s also pertinent to note that Bulgari also holds the title for the smallest (round) mechanical movement produced in this century, with the hand-wound Micro-Caliber Piccolissimo, which was first equipped to a Serpenti Misteriosi, and measures just 12.3mm in diameter.

Serpenti Tubogas 

Since it really kicked off the modern era for the Serpenti, the Serpenti Tubogas functions as the hero piece of the larger Serpenti identity. It’s probably the one that first comes to mind when you think of the Serpenti; it’s become so ubiquitous. Across the collection, the snake-head, tear-drop shaped case measures 35mm in diameter, paired with the fluid, articulating (you guessed it) Tubogas bracelet, most commonly with one or two wrapping spirals (though some models go up to five coils) that slither along its wearer's wrist. 

The dial language is sleek and simplistic, with large Roman numerals marking 12 and 6 o’clock, and the rest marked by slightly trapezoidal indices set against a guilloché-textured backdrop. Across the collection, a pink rubellite cabochon is set into the crown, and models powered by the BVS100 Lady Solotempo Automatic Caliber feature the appropriate “automatic” script on the dial. Still, the collection remains predominantly quartz-powered. At Watches & Wonders 2026, Bulgari harkened back to its goldsmithing roots with the “Studs” capsule collection, which featured Serpenti Tubogas models embellished with “clou” studded motifs along the slithering bracelet. 

Serpenti Seduttori 

Making its official debut in 2019, the Serpenti Seduttori remains a relatively new cast member in the larger Serpenti universe. It’s kind of the “jeans and a T-shirt” Serpenti model, albeit a glamorous one at that. The case in this instance measures 34mm in diameter, and forgoes the wrapping bracelet in favor of a bracelet made of hexagonal, snake-scale-like links. The cabochon-cut rubellite crown is still at play, and there are both smooth, polished bezel options alongside diamond-set case options. The dial language is the same as its Tubogas sibling, with either white opaline or black lacquer options for the backdrop. To my eye, the unadorned, black-dial model in all steel is the most unisex option in the entire Serpenti family. Again, the same movement rules apply here – if the dial has "Automatic" on it, then it's powered by the Lady Solotempo. If not, it's rocking with quartz.  

Serpenti Aeterna

Though I did refer to the Seduttori as being somewhat of a new addition to the Serpenti line, the Serpenti Aeterna really is the newest kid on the block. Introduced in 2025, which was, coincidentally, the Year of the Snake, the Aeterna is an entirely new expression of the snake motif. Sculptural and minimal, the Serpenti Aeterna is defined by its wrapping, rigid, bangle design. The serpent motif is less obvious, but the silhouette of both the bangle and the arrow-shaped case makes its connection undeniable. 

Made only in precious metals, the full-pavé dial complements the inner bangle, which is set with sparkling, brilliant-cut diamonds in a snake scale-like patterning. The diameter of the actual watch portion measures a teeny 24mm, and the bangle bracelet has a hinging mechanism that opens and securely closes around the wrist. At this year’s Watches & Wonders, the brand unveiled an all-yellow-gold model alongside a rose-gold model encrusted with a bouquet of colored gemstones. 

Serpenti Misteriosi 

The ultimate high-jewelry expression of the Serpenti watch, the Misteriosi is also among the most faithful to Serpenti designs of the mid-20th-century, and one of the most literal snake interpretations in the collection. It’s the Serpenti with a secret, cleverly concealing the hidden watch mechanism right in the very anatomically correct snake’s mouth. And, what might be the most fun detail of the design is that the watch is revealed with a press of the snake’s tongue. 

In 2022, the Serpenti Misteriosi became not only a feat of fine jewelry, but the watch itself became much more complex, debuting the aforementioned Micro-Caliber Piccolissimo mechanical movement within. The winding crown is cleverly positioned on the back of the watch, which can actually be popped right out of the Snake’s head. Though the articulating, precious-gemstone-encrusted scales that make up the coiled bracelet look quite rigid at first glance, the bracelet itself is quite flexible and pliant, and expands and bends to wrap around the wrist. 

Serpenti Spiga

The Serpenti Spiga shares much of the same DNA as the Serpenti Tubogas, but is executed with even more of a high-jewelry bent. Like its sibling, it derives its name from the bracelet it's paired with. The Italian word for “wheat stalk,” or “spike,” the Spiga symbol has been associated with abundance and prosperity since antiquity.

The Serpenti Spiga’s wrapping bracelet (which comes in both single and double coil options) features a snake-scale-like, woven pattern of interconnecting diamond shapes, shifting between diamond-set details and abstract, wheat stalk engravings into the gold bracelet itself. The watch case measures 35mm in diameter, and this extension of the Serpenti collection is only made in yellow and rose gold. Bulgari has had a little fun with the dial variations for its Serpenti Spiga, currently offering malachite, mother-of-pearl, and black lacquer renditions – all of which are quartz-powered. On the more minimalistic end, Bulgari has also introduced Serpenti Spiga models in sleek, black ceramic. 

MB&F Serpenti 

While I would argue that the entire Serpenti watch collection is quite daring in and of itself, the 2025 collaboration with MB&F ushered in what is inarguably one of the most radical interpretations of the snake motif we’ve seen yet. A total work of horological art, the MB&F Serpenti is a futuristic, just plain insane (in the best way) interpretation of the brand’s icon. The piece homes its focus on the snake’s head design completely, forgoing any of the familiar wrapping or serpentine bracelet in favor of a simple rubber and velcro strap. Complex curves and five different sapphire crystals create the snake’s head design, with a custom, manual-winding MB&F movement within. 

The “brain” of the snake is the massive 14mm flying balance wheel with four traditional regulating screws, which operates at 2.5 Hz and is held in place by that 3D balance bridge, which is adorned with the "Bulgari X MB&F" text. The time is all in the snake’s eyes, detailed by two thin, aluminum domes. The left eye tells the hours while the right eye denotes the minutes, detailed by two pointers that look like vertical pupils. The case measures 39mm wide, 18mm thick at its highest point, and 53mm lug-to-lug.  The bulbous front end of the watch dramatically slopes downward towards the rear (or the top, if you’re wearing it on the wrist). Both crowns are integrated into the rear lugs and are used to set either the hour or minutes; between the two is another piece of sapphire that almost resembles a panel. Extremely limited in nature (with just 33 pieces being made of each of the three specific models), this effort was representative of not only the craziest Serpenti interpretations, but also of one of the most impressive watch collaborations of all time.
