BVLGARI, Tubogas

$11,500.00 USD

The Tubogas bracelet, comprised of gold or steel bands wrapped around a steel core, symbolizes Bulgari's jewelry design. In the 1940s, Bulgari created a stylized serpent watch by inserting a watch dial into a Tubogas bracelet (a design inspired by industrial woven-metal gas pipes). This exquisitely preserved circa 1970s BVLGARI Tuboga tension bangle bracelet watch is the ideal accessory for any occasion, day or night. It features an oval case measuring 21.5 mm by 17 mm surrounding a black matte-toned dial with Arabic numeral and stick-shaped hour indices for greater contrast.

The Bulgari Serpenti collection was inspired by the "Tubogas", which has existed in various forms since the 1940s. The Tubogas took years to design, taking cues from gas pipelines and assembled with a metal coil surrounded by interconnecting precious metal bands. 
Tubogas translates literally to "gas pipe" and is the descriptive name given to a type of chain formed from a pair of interlocking gold strips wrapped tightly together. This forms a flexible and hollow tubular necklace/bracelet that requires no soldering.
Several models, including this lovely example, were operated with small watch movements by Jaeger-LeCoultre, Audemars Piguet, Vacheron Constantin, and more.
Elegant and versatile, this BVLGARI Tubogas tension bangle bracelet watch is the perfect accessory for any occasion, day or night. It is a stunning statement piece for your wrist that will complement any outfit.
Case, dial, and movement are all signed.
The hallmarks engraved include BVLGARI, 18k, ITALY, 1L, 36, and a visible hallmark on the left side of the case.

I recently purchased a watch using Chrono24 from the dealer Twain Time out of New York and my experience was beyond compare. The level of communication exceeded my expectations and the quality of the watch I received was better than pictured.

Kathryn Robbins

Exceptional service! I am so happy with my purchase. Because of the pandemic I had to rely on photos rather than visiting in person. In every way Twain Time exceeded my expectations. I highly recommend them.

Daniel Lee

I just wanted to highlight their commitment to customer service, even during these pandemic times. My entire experience was terrific - from start to finish. They are incredibly knowledgeable and really want to understand what the client wants, never pushing the sale. Regarding the condition of my watch - I was very happy to see that the watch came in impeccable condition, even better than the description on their website. I dealt directly with Ornella and found her very helpful and caring as well. I bought my watch through the phone and she took care of me during the entire process. Highly, highly recommend Twain Time.

Erik Barrios

I came across Twain Time's Instagram account and saw that they were listing a watch I had been looking for. They were very responsive to inquiries and readily provided additional information about the piece (including condition, service history, additional pictures, etc.). When I received the watch, the condition was as good as described and they encouraged me to contact them if there were any issues after the fact. I would happily deal with them again.

Patrick Koballa
