The Serpenti Tubogas Ref. 103648 is a masterclass in Bvlgari’s “Two-Tone” aesthetic.1 While the all-steel models are architectural and the all-gold models are opulent, this bi-metal version offers the perfect balance—the durability of stainless steel combined with the classic warmth of 18 kt yellow gold.2
Bvlgari Serpenti Tubogas: The Bi-Metal Icon (Ref. 103648)
Merging two of the most iconic emblems of Bvlgari’s design, the Serpenti Tubogas 103648 coils the sinuosity of the snake with the contemporary soul of the Tubogas.3 In this single-spiral edition, the “drop” shaped head is transformed into a jewelry masterpiece, framed by a halo of light and accented by precious metals.4
The Art of the “Snake”
-
The Bi-Metal Coil: The single-spiral bracelet is a feat of engineering, intertwining 18 kt yellow gold and stainless steel without a single solder.5 It wraps around the wrist with a “tubular litheness,” providing a flexible fit that mimics the fluid movement of a serpent.6
-
Diamond-Set Bezel: The 35mm stainless steel case is elevated by an 18 kt yellow gold bezel set with 38 round brilliant-cut diamonds.7 This contrast between the cool steel case and the glittering gold frame creates a striking visual depth.
-
The Guilloché Soleil Dial: The white opaline dial features the signature guilloché soleil (sunbeam) treatment.8 Hand-applied yellow gold indexes and Roman numerals at 12 and 6 o’clock ensure perfect legibility while echoing the gold accents of the bezel.9
-
Cabochon-Cut Rubellite: A hallmark of Bvlgari’s jewelry heritage, the 18 kt yellow gold crown is set with a vibrant pink rubellite, adding a singular drop of rich color to the monochromatic silver and gold palette.10
