It should be a new cool toy !
In my opinion, the fake screw could stay, but they must be moved inside the watch body but not external (a bit like Timex watches). Actually it looks to much like a bike computer and not a running/hiking watch.
I really like the addition of the barometer to improve height accuracy.
For me, there is enough inside, but if you want this product to be used by people who need weather forecast information, it seem that you target people doing moutain rides.
In this case weather tendancy is very important, but also as the speed during climbing or hiking is not very fast, the e-compass is a must to find you route.
Both barometer and e-compass should be present in this product.
As it is done in the Keymaze 700 (an improved GH-615 distributed by Decathlon) the e-compass should only be active when there is no speed, in order to save battery life.
As the watch body seem large enough, and as there is not to much waterproofing need because of the barometer, what about adding a slot for µSD card to store datas instead of using the watch's controler memory, for extra storage or long trail at 1 position/second + height & pressure ?
When will it be released ? I want one !
