Vintage Der Doppelchronograph 3711 photos (more)

I had some time to get more photos of my recently acquired IWC ref 3711 Doppelchronograph. This reference was only made from 1993-1995 and still has the original fish crown. The crystal is sapphire and domed, an unusual and expensive thing to manufacture at the time. I am still playing around with the doppel feature to figure out what to sequentially time .

Hope you enjoy this one. Happy new year,

Bill
