Read MoreIWC's Portofino Moon Phase watch combines a stainless-steel case and crown with a silver-plated dial set with 72 brilliant-cut diamonds totalling 1.12 carats. The 37.1mm case houses an automatic self-winding movement (calibre 32800) with a moon phase display, central hacking seconds, and a 120-hour power reserve. The convex sapphire crystal has an antireflective coating on both sides. Made in Switzerland, the watch is water-resistant to 5 bar (50 metres).
The automatic movement winds itself through wrist motion; it can also be wound manually via the crown. The crown sets the time and moon phase. The quick-change system allows the strap to be swapped without tools.
