Diagono Price Guide 2026

The Bvlgari Diagono represents one of the Italian luxury house's most significant horological achievements since its introduction in 1998. Conceived as Bvlgari's answer to the modern sports watch, the Diagono was designed by Gerald Genta, the legendary watchmaker behind numerous iconic timepieces. The collection marked Bvlgari's commitment to serious watchmaking while maintaining the brand's distinctive aesthetic sensibility. The name "Diagono" derives from the diagonal lines that characterize the watch's case design, a geometric motif that has become synonymous with the model across its various iterations.

The Diagono's design is immediately recognizable through its cushion-shaped case with distinctive diagonal fluting on the bezel and case sides, creating a dynamic visual pattern that catches light from multiple angles. The watch typically features a sunburst dial with applied indices and a date window, available in various dial colors including black, blue, and silver. The collection has been produced in stainless steel, titanium, and precious metals, with case sizes generally ranging from 35mm to 42mm depending on the reference. The Diagono is available with both automatic and quartz movements, with many models housing Bvlgari's in-house calibers or respected Swiss movements.

Collectors should note that the Diagono line includes several notable variants, including chronograph versions and GMT models, each with distinct reference numbers and specifications. When evaluating examples, condition of the diagonal fluting is important, as this signature design element can show wear over time. The Diagono remains a cornerstone of Bvlgari's sports watch offerings and represents an excellent entry point into the brand's watchmaking heritage for collectors seeking Italian design combined with Swiss technical expertise.
