The Classic Fusion 511.NX.7071.LR, seen from the bench

The Hublot Classic Fusion 511.NX.7071.LR is a 45mm titanium case watch with integrated lugs and 20mm lug width. Powered by the Hublot HUB1112 movement, it displays hours, minutes, seconds, and date. The titanium case combined with resin inserts creates a visual contrast between industrial material and lightness, with a Racing Grey colorway that emphasizes the satin titanium surface and resin texture. The watch is designed for daily use with scratch-resistant sapphire crystal and screw-down caseback.
