This is a solid watch for the money. I think if you are looking for a training watch that doesn't break the bank, this is a good option. I looked at a ton of options, and I know there are some even cheaper entry level options, but this Ironman was a little bit of a step up in appearance and quality. To me it's worth it to get this over something in that $20 to $30 range. The Ironman was more stylish and less bulky than a lot of those options. This watch has a nice sized face that makes it easy to see without being so large that it's too much. There are some of these entry level sports/military watches that are just enormous. I'm not a huge guy so this was a much better option. One thing I am really liking is how flexible the strap is. The material has a nice give to it making it a very comfortable watch to wear. I've had some watches in the past where the bands were just too stiff and made the watch very uncomfortable. It's easy to understand and operate. I didn't even read the manual and had everything figured out after 5 or so minutes. Unless you are really going to step up and get a GPS smart watch in the $200 and up range, this watch is a great option.

Great watch for healthcare workers

This is a great watch that I use for my nursing clinical rotations at hospitals. It has been washed and disinfected many times and it still looks new. I can read the time without my glasses I wear for astigmatism. The light is good for nighttime or darkened rooms. I think the alarm and hourly chime are harsh sounding, but they serve their purpose if needed (The beep of a Casio digital watch is preferred, for a frame of reference).
