this is a rare iwc da vinci sl line dresswatch from the late 1970s in beautiful unpolished condition. the 32mm steelcase wears comfortable and elegant and it´s even having the original IWC sticker on it´s caseback. the dial is flawless but the mineralchrystal has some little signs of wearing. the handwound iwc caliber is running exactly no being in the need for a service. it comes on a black lizzardleatherstrap. this is definitely one of the rarer watches of IWC´s SL line, that also represents the great era of Gerlad Genta´s IWC designs.
