IWC has updated the Portofino Automatic Moon Phase 37 (Ref. 4590). This popular watch is now also available with a silver-plated dial instead of a mother-of-pearl dial, making it blend even more harmoniously with the overall image of the Portofino family.

The top-of-the-range model, with a case and Milanaise mesh bracelet in 18-carat red gold, is adorned with a total of 78 diamonds (Ref. IW459010).

Two other models are also being released with 66 diamonds on the bezel and 12 on the dial: one in an 18-carat red gold case with gold-plated hands (Ref. IW459009) and the other with a stainless-steel case and rhodium-plated hands (Ref. IW459008).

The fourth variant has a stainless-steel case, gold-plated hands and 12 diamonds on the dial (Ref. IW459011).

These three watches (IW459008, IW459009 and IW459011) are fitted with exquisitely finished alligator leather straps by Santoni.
