In superb condition, this 18ct yellow gold IWC perpetual calendar was one of the early Novecento perpetuals to be issued and comes complete with its original papers, recent IWC service history and an IWC box. Fitted to its solid 18ct gold beads-of-rice bracelet, this example is also supplied with two brand new IWC alligator straps and an additional IWC 18ct gold pin buckle so one has the option to choose between the two looks. Powered by IWC's automatic, Kurt Klaus designed perpetual calendar movement (with Frederic Piguet base) and under IWC service warranty.
