I'm querying if there is an online archive for IWC watches. I'll use Omega as the example as that's another timepiece manufacturers website I familiar. On Omega's website, there is a 'watch-finder' tool. This enables anyone to enter the model number of an Omega, even discontinued (I have not tried vintage), displaying the watches specifications and a photo in the same format as their online catalogue advertised watches.
Is there an official, and if no, and unofficial online site to look up discontinued models? For example; lets use the 3717.
