Is this 16570 or the new 216570? I'm not familiar with the Canadian watch market but USD$7,000 for the older reference NIB is way too much! The new EXP-II is USD$8,750; just started seeing them on the grey market and they have not shown on many of the authorized dealers yet. I understand you wish to place a layaway from an AD but if you shop around, there are plenty of good deals around. On the grey market, you can find a NIB with stickers, card, tags, manual, box and active warranty for much less than what an AD wants. You should conduct online research on some watch forums before you commit. Bear in mind resale value is lower on the EXP-II compared to other sports model. Also a price increase of 8% is coming in October, which applies to new/used from ADs and grey dealers. I have owned few sports models (including white dial EXP-II); needless to say, only a SD and a 50th Sub LV remains in my collection.
Shop smart with your hard earned money .. have fun and good luck!
