Christopher Ward C1 Bel Canto Classic

The Christopher Ward C1 Bel Canto Classic is noted for its laser-etched guilloché dial featuring Roman numerals and a blue handset, a departure from the original's sunray dial and applied indices, necessitating a more domed sapphire crystal. It presents a chiming complication with a visible hammer and gong, housed within a 41mm grade 5 titanium case that exhibits brushed and polished finishes. The watch is powered by the FS01 movement, a modified Sellita SW200-1 with a chiming module, and offers 30 meters of water resistance. Reviewers highlight the meticulous hand-finishing on the visible chiming mechanism. Overall, reviewers praise the Christopher Ward C1 Bel Canto Classic for its intricate guilloché dial and the impressive chiming complication housed in a titanium case.
