I bought mine in Holland and they are selling only two colours, the orange is not for sale here.
I've aked the American site if I can by a bezel and band but they are not willing to do that because of not being water proof after the bezel has been removed. So if you want a different colour you can only do they when you buy it.
Indeed it is a great watch, very rugged, it is big but very nice to ware it as it is not heavy. A lot of apps are working with the watch, so of them I did not expected, I can change the light settings of my Bluetooth lights in the house but that is more related to the androidwear.
I hope, one day, there is someone mad enough to unscrew the bezel to find out that there will be indeed a problem with the watch not being waterproof anymore.
I'm very happy with the watch but less with the site and not being able to buy bands and other accessories. In Europe we can not buy from the american site and on the European site bands can not be bought.
I hope when androidwear 2.0 is coming out the watch will still run smooth and that we are going to get other updates as well from Nixon but for now it is thumbs up for the Nixon The Mission
