Created circa 1970, this Bulgari Tubogas Serpenti wristwatch with an automatic movement is composed of 18K tri-color gold. It is designed as a stylized snake with a flexible, coiled body of rose and white gold tubogas links terminating in a cushion-shaped yellow gold head, the dial with baton hour indicators, enclosing an automatic Swiss movement. Winding comfortably around the wrist, this unusual Bulgari watch with its superior automatic movement is a beautiful and wearable Serpenti jewel expressing streamlined 1970s chic and artistic abstraction.
