About 15 years ago was active in road racing. Had an Ironman watch back then. Great tool during training and racing to log laps, split times, etc. Had night light, alarm and other nice features. Served me well long after my competition days were over. A matter of fact, I still had it just about a few weeks ago. 15 years of bonding, me and my watch. Snow, rain, sweat, faucet water, the works.  The watch earned it's Ironman tag. Did have to change the battery 2 or 3 times during that time which was very easy with the right tools. No longer running except occasionally for exercise, but I know a good workhorse when I see one. You won't be disappointed. Hope this helps. Be well.
