Need help indentifying IWC Porsche Design Model

Hi everyone,

I recently purchased this IWC Porsche Design model, see photo.

It's a men/midsize (32mm) with titanium bracelet and quartz movement. Can anyone help me identify the IWC reference model and age of this model?

It's a ref. 3307

It seems to be a ref. 3307 black "aluminum" and a predecessor to the ref. 3317 in black titanium.

Regards,
Jack Freedman

RE: It's a ref. 3307

It appears that it has a titanium case & bracelet, though. Would the "black" titanium be similiar in apperance and weight to the titanium model?

Is the ref. 3307 rare and when does it date from? I have tried to find information online, but I can't find anything.

It is anodized aluminum.

I found this model in the catalogs from 1980 to 1982.

Yes, seems to be rare, however, very sensitive and not a collectors item.

Regards

Heiko
