IWC Schaffhausen Iw504506 Portugieser Perpetual Calendar Tourbillon

Owners widely praise the IWC Schaffhausen Iw504506 Portugieser Perpetual Calendar Tourbillon for its easy crown-based setting of the perpetual calendar functions and its elegant design, with some noting its appeal among the ultra-wealthy as a daily wear piece that complements suits. Reviewers highlight the striking dials, often featuring multiple lacquer layers, and an updated case design that contributes to a slimmer profile. However, the watch's 45mm case diameter is considered large by some owners, and its high price point and potential for depreciation on the secondary market are noted drawbacks. Some users question the accuracy and practicality of the year complication, with one owner finding the rotor engraving needs correction and another stating the day, date, and month setting can be difficult.
