The Classic Fusion 542.NX.7170.RX, seen from the bench
The Classic Fusion 42 Titanium is a 42mm watch from Hublot's Classic Fusion family, featuring a grade 4 titanium case with resin inserts and a clean, unadorned design. It houses the internal HUB1112 caliber movement with hours, minutes, seconds, and date display. The 20mm lug width accommodates compatible straps, noting that Hublot's attachment system integrates spring bars into the strap itself rather than the case.
