Hi Barrie,
well the subject of manufacture movements is certainly worth a discussion of
its own. And everyone certainly has their own opinion.
Personally, I also like the IWC watches with the basic ETA calibre and the
mechanical IWC additions such as the Split Minute or the Split Seconds of the
Doppelchronograph. The great JLC base calibre in my Deep One has also worked
perfectly for over 20 years.
Too often I have experienced (independent of IWC) bad and expensive manual
calibres. And at the same time experienced great moments with inexpensive and
high-quality and reliable mass-produced mechanics.
But the Ref. 3227 has its own IWC calibre. But even without it, I wouldn't
like this watch any less. For me, it's always the sum of all the parts.
Cheers,
Sascha
