Hi
i received the new arktos and have make some pics from old and new model side by side
i see some differences between both models:
case: older case is more shiny... new one is more brushed (but bezel is different - more shiney as case)
bezel: new has bigger and thinner markers. Older bezel is more round and more shiney. Old model less clicks - new model 60 clicks
caseback: few differences... new one has serial number engraved, but the engraving on old caseback (globe) is closer to genuine
crown: new one has may 1mm thicker crown??? New crown fit tighter.
crownguard: new crownguard look closer to genuine, but the older one is BETTER quality and fit better. Old one is more round.
glass: new one looks better, but old one is also good.
AR: old model has no AR, new model may light AR... but not much improvement
date magnifier: new is MUCH better
thickness: old model looks 1mm thicker???
weight: old one weight 128g - new 135g
all in all is the new model better... best upgrade is the bezel with correct markers and the date magnifier. Glass is also nice... But this crown guard is HORRIBLE
Old model is also a good watch and if you are not a arktos enthusiast, you don
