Stunning Italian 18k yellow gold weighing an impressive 159.7 grams with an 21.5 mm width. Measuring 16.25 inches in its relaxed fit and extending to 18.25 inches stretched out. Finished with an endless clasp and figure eight safety. Signed Bvlgari and stamped Italy.
Bvlgari helped define the modern Tubogas look from the 1970s into the 1980s, taking the industrial gas pipe inspired construction and turning it into one of the house’s most recognizable gold designs. Flexible, fluid, and engineered without soldering in the traditional sense, Tubogas pieces became signatures of bold Italian luxury during the era.
This one stands out for its rare heavy scale and substantial width while still laying smoothly against the neck. High polish finish with that rich deep yellow gold color vintage Italian gold does so well.
The name “Tubogas” comes from flexible industrial gas piping because the construction mimics those coiled metal tubes.
The technique was made using precision wrapped strips of gold formed around a core mandrel with tension and pressure rather than traditional soldered link construction. Specialized rolling and coiling machinery was used to tightly wrap long gold strips into the flexible tubular form. The better houses had extremely refined engineering because the pieces needed to flex smoothly while still feeling substantial and seamless.
