About the Classic Fusion family
The Classic Fusion was introduced in 2008 as the slimmer, dressier descendant of the original Hublot of 1980, with a round porthole case and a bezel held by six H-shaped screws.
The catalog lists more than two hundred references, including time-only, date and chronograph models, in titanium, King Gold, ceramic and other materials, many with the HUB1112 automatic caliber. Dealers identify the size, material and dial from the reference and check the strap and papers.
