This is a very rare IWC Da Vinci Sl Line men’s dresswatch from the late 1970s. It´s design clearly bears the signature of the great Gerald Genta, just like all other IWC SL Line watches from the 1970s. The handwound IWC caliber is running exact with no need for a service. It’s 32mm steelcase wears quite big regarding it’s design with integrated 23mm bracelet and was definitely meant to be a men’s watch back then in the 1970s/80s. The deep black glossy dial has a slight spider effect on the top layer of lacquer, which is almost impossible to photograph as it is very faint. The watch currently fits wrists with a circumference up to 17.9cm or smaller. Additional extension links can be ordered upon request.
