I have a job that causes my watch to go through massive amounts of abuse, immersed in questionable fluids, covered in sometimes disgusting debris, and often the object of violent impact. I always get massive stainless steel man's watches, as the delicate stuff, with plastic or leather bands do not stand up to chemicals, claws, & teeth very well. My various Casio watches have all given into the abuse eventually, but they have helpful features, good prices, and last a lot longer than any other brand I've tried. I've been a veterinary technician for 33 years, and I love my Casios.
