Arguably Bulgari’s most significant contribution to the world of fashion, its iconic Tubogas design was inspired by the functionality of the kind of ordinary gas pipe you might find at any filling station. The idea was to seamlessly wed flexibility with durability in a ceremony of sheer splendor.

The process of marrying these elements is one that requires intense focus and discipline. Thin strips of gold are heated to the point of malleability, then expertly wrapped around a metal core, which is then removed as the strands of gold cool and interlock into a single unsoldered band. This exceptionally demanding method of construction is made even more so when multiple colors of gold are incorporated into the timepiece. The jeweler must maintain constant control over the different temperatures required to bring each strand to the optimum softness required by the process.

Such is the case with this exquisite tricolor Tubogas watch. Bands of three different types of 18 karat gold - white, yellow, and rose - are woven into an opulent prism that winds around the wrist of the wearer for a comfortably firm hold. But even more exceptional than the bracelet is the 22mm square case that has proven to be a highly sought-after oddity among the vintage Bvlgari stable. But while its shape may prove a rare deviation from the round heads that usually characterize the Tubogas, it makes its pedigree known by housing a familiar charcoal dial (highlighted by gold Arabic numerals at 12 and 6), as well as a quartz movement for the collector who prefers to worry less about maintenance, and more about showing it off. We love how this timepiece doubles as a chic statement bracelet.
