In my experience the dial works best in lower light conditions. I find the online exclusive 1385 or the 662/663 more to my liking, even if it means giving up on the cut out dial. The new 45mm pams are nice, just haven't found one that speaks to me yet.
I think this is a watch to be seen in real, before any final feeling... But if you already think that 45 mm is too small for you, as a Panerai, watch, then pass;;;
