Hey guys. A little about me. I flip homes for a living. When I'm not out buying homes and doing all the business stuff, I'm doing hands on work which can be a little messy (caulking for instance). while working I listen to music on my bluetooth headphones hours on end. The only inconveniences are when I have to take my phone out to look at the screen to change artists and songs & when I have to see who's calling or while I'm busy or in a bad position like on a tall ladder or under a sink doing plumbing. Having to take the phone out to talk while I'm drilling or cutting sheetrock is also a likely scenario for me. So I guess my question is if I want the Apple Watch almost entirely for the music controls and the ability of talking through the watch during calls (which I have no problem doing) will I be satisfied purchasing the $400 black Sport version? I really only ask that those 2 functions work flawlessly since they're native. All the other functions would be nice added perks for me which I'm positive I'd come to use more often. I have no problem spending $400 for a watch that might get a little dirty at work but I would be be bothered if it didn't work efficiently most of the time for those two basic tasks. Thanks for your replies.
