I am an EMT, and don't know much about watches. What, in your guys' opinions, would be a good watch for my job? I work nights, sometimes in environments with little light. The watch has to be somewhat affordable, durable, resistant to water damage, and comfortable (12+ hour shifts). I like the look of tritium watches but I don't know what is the best to buy. I'm also hoping not to spend more than 300 dollars. What do you guys think would suit my needs? I like the look of the Traser P6508 Blue, but again, I don't really know much about my options.
