problems getting set up with my apple watch sport 42 mm

hi all so i got my apple watch sport 42 mm yesterday yet when i turned it on when had it on charge overnight i triple clicked the crown and i hear a rising triple tone sound (almost like an error sound?) and voiceover is not coming up. have i accidentally turned on zoom or something by mistake? i'm not really impressed as when i somehow? got voiceover up just went doing doing doing all around the watch face as though i was on a blank screen. i can't get to an apple store until next week and my fourteen day return window here in the UK started yesterday. could they get in to my watch over the phone and turn on VO?
