It is funny -- the DS looks a lot bigger side by side, but in isolation it looks perfectly "correct" in size on the wrist, as does the Dato. A real tribute to Lange's ability to build pieces that have the right proportions.
I had the same impression when I tried on a Dato Perpetual for the first time recently -- very different proportions, but they really worked.
Sadly, for me the Zeitzone (a watch that I otherwise adore) seems a bit too wide for its depth on my wrist -- not that I may not end up with one!
Thanks again for your kind comments, especially on the photos -- I'm back to my "tabletop studio" in my rented apartment in Seoul, which makes photography a little tougher...
Best,
Gary
