The Portofino Automatic Moon Phase 37 combines poetic complication with refined elegance. Set within a 37 mm 18 ct 5N gold case, the silver-plated dial is framed by a diamond-set bezel with 72 diamonds totalling 1.12 carats. At 12 o’clock, the moon phase display adds a romantic flourish, showcasing lunar beauty with remarkable precision.

At its heart beats the IWC-manufactured 32800 calibre, the first in the 32000-calibre family to integrate a moon phase module. Highly efficient with a five-day power reserve, the movement is finished with a gold-plated rotor and blued screws, visible through the sapphire case back. The convex sapphire crystal with antireflective coating ensures clarity, while a taupe calfskin strap with a quick-change system provides comfort and versatility.
