I have to admit to being a bit of a watch fiend, having one for almost everything I do, but this is one of the most useful, yet cheaper priced items I've come to enjoy.  When I work out I like as much information as I can get, so for running and biking I have a watch for that, but for swimming I needed a watch to help me count my laps and log my times.  The Timex Ironman 100-lap watch does this quite well.  I first got a Timex 50-Lap watch that I was able to find locally, but 50 laps is very limiting so when I found this watch for less money and a bigger face that had the lap/split time and lap number on the screen at all times I knew I had a great product.  When you're finished with your laps just save your workout.  The watch will then calculate some information like average lap time and best lap.  I haven't completely messed with their data, but I think they average your times by throwing out the lap times that are the outliers, which is good for the accidental laps where you hit the wrong button, but it's not as great when you did a few sprint laps and they don't show up as your best time.  If your best time isn't on there you can still recall it by going through each lap individually, but I think my sprint laps sometimes aren't listed as my best laps.  I haven't messed with this feature much because it isn't important to me, and removing the outliers is good for looking at your actual pace.  I have been able to push myself a bit more in the pool by having actual numbers to compare, which is very helpful. The other features on this watch I haven't used much, but for someone who can't afford a GPS watch and can use maps or a track this watch would be great for running or anything with laps or intervals.

It has up to 9 interval timers and once finished it can either stop or repeat the sequence.  It can do what's called chrono at the end, where it just switches to the chronograph feature after your timer or interval timers are finished. Overall this is a great watch and for most people who enjoy doing anything with laps look no further.
