This Bulgari Diagono Professional Chrono Amplificator, reference CHW40GAM, is a sophisticated 18k white gold wristwatch designed for yacht racing. The timepiece measures approximately 40mm in diameter and is paired with a brown leather strap featuring an 18k white gold deployant buckle.
The watch is powered by an automatic 39-jewel movement based on an ETA 2892-A2 caliber, integrated with a Dubois-Depraz 2027 regatta module to facilitate flyback chronograph functionality. The white dial is marked "Bulgari" and "Swiss Made," and it incorporates a distinct three-register chronograph layout alongside a red, white, and blue regatta countdown display. The case, dial, movement, and buckle are all signed by Bulgari.
This model features a fixed bezel engraved with the brand name. The mechanical movement is configured for chronograph operations including starting, stopping, and resetting functions.
