Here you can see the different models. Maybe it would be an idea to make a
revision on the text with either refering to ref. 3500 or ref. 3524 with the
correct image ?

Maybe a moderator can have a look at this page

www.iwc.com/en/articles/journal/history-of-dive-watch.html

There is writen about the Porsche Design ref 3500 - but the image is the ref
3524 ?

Thanks Tonny. Yes both very different, but both undoubtedly unique IWC watches
:-)

my ref 371815

Hello everyone,

Although I am not totally new here (I have posted already one or 2 questions),
I think it's better that I introduce myself here.
Erik is the name and live in the Netherlands, and have been an IWC fan for
many years. About 15 years ago I visited for the first time the factory in
Schaffhausen, and about 10 years ago a second time.

At this moment I own 2 IWC's

The Aquatimer 2000

and recently my new Double Chronograph Ceratanium

Do you maybe know if the original ones came as brass or as stainless steel
version ?
I have found this number : IWIWA03937 but don't know if that was the original
one for the Aquatimer 2000 ?

Thanks Mark

I remember when I bought the Aquatimer IW353804 way back in 2005-2006 there
was a special tool inside the box delivered for changing the strap.

Does anyone know if this one is still available for purchase ?

Thanks
