The Bulgari 103901 is a quintessential Serpenti Seduttori. Its 34mm 18K rose gold case eschews the traditional round shape in favor of a teardrop-like silhouette—narrowing at the top and gradually flaring outwards towards the bottom—which is, in fact, a highly stylized, geometric interpretation of a serpent’s head https://www.firstwatchclone.co.
Encircling the dial is an 18K rose gold bezel set with 36 brilliant-cut diamonds, totaling approximately 0.6 carats. These diamonds do more than simply add a touch of luxury; they effectively trace the contours of the teardrop-shaped case, further accentuating the silhouette of the “snake’s head.”
The most eye-catching feature of the watch is undoubtedly the green malachite dial at its center. As a jewelry brand renowned for its mastery of colored gemstones, incorporating natural stone into its timepieces is a natural progression for Bulgari. Malachite is distinguished by its varying shades of green, which form layered, horizontal bands; without the need for complex guilloché or sunray patterns, the stone naturally creates a striking sense of depth and dimension as light plays across its surface.
The pairing of green with rose gold tempers the watch’s cool aesthetic, lending a warmer tone to the dial. Complemented by elongated Roman numerals at the 12 and 6 o’clock positions and rose-gold baton markers elsewhere, the design harmoniously blends the opulence of traditional Roman jewelry with modern geometric styling.
The bracelet is also crafted from 18K rose gold; its interlocking hexagonal links resemble neatly arranged snakescales, creating an effect akin to a solid gold bracelet. Crucially, the intricate articulation of these links allows the bracelet to curve naturally around the wrist—offering the visual impression of a continuous sheet of golden scales while remaining supple and comfortable to wear. A folding clasp secures the bracelet; once closed, it blends almost seamlessly into the design, further blurring the distinction between a timepiece and a piece of fine jewelry. The top of the 18K rose gold crown is set with a cabochon-cut pink tourmaline.
Turning the watch over reveals a transparent case back that offers a direct view of the internal Lady Solotempo BVS100 self-winding movement. Officially unveiled in 2025, this movement was developed and assembled at the brand’s watchmaking atelier in Le Sentier, Switzerland. The unique geometry of the Serpenti snake-head case makes it difficult to source off-the-shelf movements that fit the specific size and shape requirements while simultaneously offering automatic winding and a respectable power reserve. Measuring just 19mm in diameter and 3.9mm in thickness, the movement comprises 102 components and 28 jewels. Despite its remarkably compact size by modern mechanical standards, Bulgari has retained a full automatic winding system and central hour, minute, and second displays; the movement operates at a frequency of 21,600 vibrations per hour and delivers a 50-hour power reserve.
