The Hublot Classic Fusion 541.NX.7070.RX is a 42mm chronograph combining titanium and composite resin, exemplifying the brand's Art of Fusion philosophy. It features the in-house HUB1153 movement with hours, minutes, small seconds, date, and chronograph functions. The case measures 42mm in grade 2 titanium, offering superior wear resistance with reduced weight compared to stainless steel, while the integrated resin component enhances vibration absorption and thermal insulation. The 20mm lug width follows standard proportions for this case diameter and features a curved geometry integrated into the case profile.
