The Classic Fusion 541.NX.7170.RX, seen from the bench
The Hublot Classic Fusion 541.NX.7170.RX is a 42mm titanium chronograph combining aerospace-grade titanium with resin inserts that exemplify the brand's Art of Fusion philosophy. It features the HUB1153 chronograph movement with hours, minutes, small seconds, and date. The 20mm lug width accepts standard aftermarket straps, though Hublot uses slightly oversized 1.5mm spring bar diameter on some Classic Fusion models.
