I'm a student nurse and am having trouble counting pulses because my wrist watch has the second hand that moves in "steps" and I find myself counting the movement of the watch's second hand rather than the patient's pulse. Therefore, I'm looking for a watch with a second hand that moves continuously rather than the normal second hand that moves in "steps". Does anyone know where I can buy a watch like this? I know Rolex watches have this feature but I can't afford a Rolex. Any help will be greatly appreciated.
