My watch has 2 arrows on the screen. One is always pointing at my dog, the other is always pointing at my truck. My life is dramatically improved since I started running this setup. Plus it tracks my heart rate, my Sp02, my steps, and my elevation. Lots more too but those are the things I use most often.
Oh yea, and if I decide to go play Whack FUCK just about anywhere in the world it tells me how far I am from the pin and what club to use.
If I were to wear a watch, my first electronic instructor would claw himself out of his coffin, come find me, and slap me saying 'I SAID NO JEWELRY IN THE SHOP!"
