I'm curious about the polar explorer. I've been spending most of my time wearing a vintage sub, and a couple of ultra thin's. I used to love wearing a PO 2201.50, which has spent most of the last six months in a drawer. I went to try on the 216570 earlier this week, and it felt big and heavy to me. When I got home, my PO also felt big and heavy. So I think that my impression of the watch was skewed by what I've been wearing recently. Does anyone have both the 2201.50 and the current Explorer II? I'd love to hear your thoughts on how they compare, and maybe see some comparative wrist shots. Thanks.
