I'm a first year student nurse, and I was told that I needed to start wearing a watch to clinical in order to measure pulse, respiration, etc. The watches at the bookstore were predominantly feminine (as a male, I'm just not into wearing a purple or pink wristwatch - call me crazy!). So I looked elsewhere.
The faculty recommended an analog watch with an easy to read second hand over a digital, and I totally agree with them: I think an analog is easier to read for vitals than digital. But I digress.

This little Casio fits the bill perfectly: It has an easy-on Velcro strap that's quite comfortable to wear for extended periods, its water resistant (good for frequent hand washers like me), is very light weight, and overall looks classy and simplistic. Other pluses include the luminescence that stays on 3-4 seconds after the button is released, and an easily-read white second hand that stands out well against the black face of the watch. Perhaps the biggest plus is it's price. For right around twenty bones I get a usable and comfortable watch. Time will tell (no pun intended) whether or not its as rugged as my old digital Timex. But for the student nurse on a budget, it fits the bill.
