Owner Reviews, Ratings, Comments and Criticism
I recently purchased this Timex Watches HRM-kit after my bulky Polar F6 bit the dust and didn't have user-replacable batteries. I was wanting a smaller sized watch and Timex Watches has a line of nicely sized watches so I gave them a look. The Timex Watches Race Trainer is a good looking watch off the bat and is extremely lightweight. Most HRMs are large and unsightly on a woman's wrist but this one looks very size appropriate (I'm 5'8", 142) for my frame. The display is pretty easy to read but navigating off of the main time/date page is a bit tricky. I'm probably just used to Polar's setup but I have been frustrated with the menu on the Timex. The biggest drawback and the reason I am not keeping this watch is the calorie counter so you can measure your workout energy expenditure. There is a calorie function, but it does not ask for your age or gender (two crucial factors) and only goes off of your imputed weight and your heart rate as you exercise. It's been completely inaccurate, overshooting workouts that I would usually burn 600-700 cal, it would say 1,020. Also, unlike the Polar, you cannot view calories burned while you are working out and it's hard to find them at the end of the workout also. The last (but small) thing is the ANT+ coding. Although Timex Watches claims the HRM will work with most gym equipment, I have not had any pair. Polar's coding technology, however, has never be unable to pair with equipped machines. Obviously it's a minor note, because you will always have your HR displayed on the watch but some machines have programs that work with your HRM to keep you in a certain zone, so it's nice to have that feature. All being said, I will be going back to Polar. The watches and HRMs they make now have user replaceable batteries and I think their set-up is much better suited for me.
