A:AnswerYou can download the app called Watch Styler on Samsung gear store and this will enable you to build a watch face and put your own background on it.
A:AnswerPersonally I wouldn't wear it. The watch is water resistant but I doubt it is water proof and even some products that are water proof get damaged.
You have many places in which the water might go inside the watch like the speaker and microphone so again personally I wouldn't wear it.
A:AnswerIt is worn by both, I bought this for my sister and she loves it! I may also put in here that she is tiny and it still looked good on her. Hope this helps.
A:AnswerIt is charged through a supplied power supply connected to a snap-on adapter connecting it to the watch. The battery life is more like 2 - 3 days. I doubt it would ever last 6 days. My experience with charging time is about 1 - 3 hours depending on the amount of discharge.
