It's one of the most popular IWC models in the lineup and up until now, the watch has never had an official stainless steel bracelet option. Today, IWC presents an updated Portugieser Chronograph with a stainless steel bracelet option, finished with polished and satin surfaces and a butterfly folding clasp. It will be fitted to a new reference (Ref. IW371617) that features a matching stainless steel case, a silverplated dial, and IWC's in-house 69355 automatic movement. And yes, you can purchase it separately.
