This is an IWC watchmaker coat. I received it at Watches & Wonders. It's a non-sale item from IWC. I received it as a novelty item. It's unused. I think it's quite rare. It's meant to be worn over clothes, so it's large and can be worn oversized like a raincoat. The front has a double zipper. The size is L, with a shoulder width of 49cm, a body width of 62cm, a length of 93cm, and a sleeve length of 72cm (it stops because of the ribbing).
