Introduced in the mid-to-late 1990s as an early cornerstone of Breguet’s Héritage collection, the Reference 3490BB offers a sophisticated, neo-classical alternative to classic rectangular models like the Cartier Tank. Executed in 18k white gold, this rare reference features a distinct tonneau (barrel-shaped) case with traditional coin-edge fluting along the case flanks and solid gold screw-bars securing the leather strap. Measuring 29mm wide by 33.5mm long (40mm lug-to-lug) with an ultra-slim 6mm profile, its unique geometry wears with the visual presence of a 36mm round watch.
The solid silvered gold dial showcases fine hand-engraved engine-turned guilloché patterning, painted black Roman numerals, blued-steel open-tipped hands, and a small seconds subdial at 6 o’clock. Powering the timepiece is the ultra-thin, manually wound Caliber 818/4, an 18-jewel movement renowned for its traditional finishing and reliable performance.
While 1990s Breguet production was strictly limited, finding a Reference 3490BB complete with its original box and papers is exceptionally rare. It represents a highly collectible example of modern haute horology—one that shifts effortlessly from formal tailoring to elevated casual wear.
