A:AnswerYes it has a count-down timer, and while I don't know exactly how loud it is it is loud enough to wake me up. Also, if i leave it in the other room I can hear the alarm going off. Hope this helps.
A:AnswerAll Apple products have a 1 year warranty and the option to purchase AppleCare+ (which in this case, provides accidental damage coverage with a service fee of $49). So if you get AppleCare+ and you end up breaking your watch, it'll only be $49 to replace it. AppleCare+ adds on an additional year of coverage and provides two instances of accidental damage over the two years of warranty coverage. Warranties don't cover theft, keep that in mind.
A:AnswerYou can get 100% money back within 15 days for sure for any unboxed products. Anything else you may have to try to call them or ask customer service.
