The Classic Fusion 521.OX.2611.LR, seen from the bench

The reference 521.OX.2611.LR is a Classic Fusion 45 Chronograph King Gold featuring a 45mm case that combines brushed aeronautical titanium grade 5 with 18kt rose gold without aesthetic compromise. The case houses the HUB1143 in-house chronographic automatic movement with hours, minutes, small seconds at 9 o'clock and date at 4 o'clock, with a rose gold oscillating mass visible through the sapphire caseback. The lug width is 20mm, a critical specification for strap replacement and daily wear comfort on the wrist.
