After 1 month the watch is working properly. I use it every day in the pool, as well as for cycling and running. I bought this model because I wanted to track my heart rate in the water and it does a great job. It has a long list of great training features, and the ability to post your workouts to Personal Trainer.com is really helpful. I have found that it is best to wet the chest strap under a tap before putting it on as this provides the best readability. The ability to change the size of the display comes in handy in the pool and is a lot easier to read. I also have an Elite Timex Ironman Race Trainer, I find the RCX5 gives more accurate readings and has many other features and it's fantastic to be able to see your heart rate while swimming (if my hand goes by I can take a look and see my heat index). The ability to read in water and the use of a personal trainer make this watch a winner for me.
