I'm in my first semester of clinicals and I bought this stethoscope and it's been working for me so far with hearing lung sounds and bowel sounds. As far as watched go that doesn't matter as much. I'd say get a water resistant one that is somewhat lightweight, and has a comfortable strap. I started out wearing a watch that had a somewhat stiff strap and a few hours in I'd want to rip it off and throw it across the room. Learn from my mistake.
