Yes, I have the WG version, 110.030. It was my first Lange. That reference was initially offered exclusively by Sincere for about a year and was then offered more widely through other Lange ADs. These guilloche versions were not initially called "Soiree." "Soiree" was used only to describe the 110.029, which was the non-guilloche version that appeared only briefly, c.2001-02. Then everyone (including Lange, I believe) started calling the guilloche version "Soiree" too, when the non-guilloche version was discontinued. They are beautiful watches for sure!
