Aquatimer IW354805 info. please.

Can someone please tell me what movement was used in the Aquatimer IW354805 ?
I've done the usual google search and used the forum search but cannot find anything.
I was admiring a watch from around 2005 so I guess it's a bought in ebauche which IWC then modified but would appreciate the facts rather than my guesswork.
Thanks in advance.

Well, it's the cal. 30110 or as it's also known as a ETA 2892-A2 but little modified by IWC. Generally a preety good movement from a service and reliability standpoint.

Thanks nono

Thanks! This is info I have been also trying to find in some of the literature. I am curious for a further lesson in Aquatimer calibres. Starting with the GST, what are the IWC calibres and their derivatives up until the present? Are they all ETA 2892-A2s?
