The po gmt is thicker than the regular 8500. As I recall,above 17 mm... But the proportions are great(43.5x17). Tryed it my self at my local ad and the size of this watch is just great.
Hi Guys have a PO GMT inbound myself... (and proper looking forward to receiving it I am too) As has been mentioned yes its thicker, but the actual case is a much more suitable 43.5 which (to me) feels significantly more at home on the wrist vs the PO Diver @ 45.5

Yup, agreed. It's slightly thicker, but not noticeable with the increased size. The GMT works best on my 6.75" wrist.
