So my old stopwatch crapped out and I'm looking to upgrade to something new. I'm training for triathlon so it will be used while running, biking, and swimming, as well as during other workouts (strength training and such). I was hoping someone around here could give me some advice! My old watch had the kind of heart rate sensor where you push a button and it reads your heart rate, but I'm looking at getting one with a chest strap.
This is what I'm looking for:
- waterproof
- heart rate monitor chest strap
- stopwatch that can do splits/lap timing with recall of the times
- lap counter
- countdown timer
- comes in women's sizes (many "unisex" watches don't go small enough for my wrist)
I was looking at some of the Timex Ironman series watches but then I saw one that said the HRM doesn't work underwater.

There are so many options and I'm so confused! I'll take any advice you have!
