hi,i know you want to be reassure and not be disappointed with your 1st buy,so look at the guide,read,and be very clear of what you want when you order,ask question to the dealer and if its not exactly the watch you are looking for do not be shy to refuse it and remember that what you are looking for Perfection does not exist and the closer you get to it the more it may cost,cheers.
Buy 2, choosing just one is a pain and after a while You will have 5 or 6 anyway. Imho the crownguard protection device and a sandwich dial are a must have one of them.
