Timex Sports Ironman Triathlon 100-Lap 51931 Wrist Watch for Men

Pros: Inexpensive, 100 lap Ironman features, can change the battery
Cons: Watch strap is absorbent fabric (sweat will make it smell in time)

Back in '94-'95 I had a very basic Polar HRM unit that only told me my heart rate and that was it. Simple, basic, but did its job very well. With any HRM, it only takes a short amount of time (a few months) before you get adjusted to knowing what ...

Pros: Digital transmission (no interference from other users), good display
Cons: Too many to list, check review below for details.

If you are serious about monitoring your heart rate, don't buy this watch. I am almost 100% certain that Timex does not actually manufacture this watch, as I have had great luck in past with Timex watches, but this heart rate monitor is junk!
...

Pros: Lapping chrono & HRM in one, user-replaceable batteries, Digital Transmission, and a low price.
Cons: Not the largest of displays (but is still large enough).

The TIMEX 51581 Heart Monitor Ironman.

The only difference between the 51601 and the 51581 is the actual wrist straps on the watch. The 51601 has a cloth strap with velcro to enable it to fasten to the arm. The 51581 has a standard rubber-like...

Pros: Affordable. Loaded with features. Accurate heart monitor
Cons: Watch face a little big.

I received my watch about a year ago and it has been on my wrist every since. You might think that is normal, but I go through watches fast. Previously I could only keep a watch for about 6 months or so. I am a professional firefighter and my job is...

Pros: You can wear the watch alone in public without people looking at you funny
Cons: Functions not as advanced as those on competing products.

When I set out in the market to find a new heart rate monitor, I looked at the various different makes available. Especially those from Polar.

I knew that in addition to a heart monitor, I also wanted a general sports watch, as I only had a...

Pros: Memo-Pad, 120-Lap Memory, Regular Watch Features, Bright Indiglo, Flix
Cons: Cycling through the alphabet, memos can only be 24 characters

Ive had the Timex 100-Lap Triathalon about a year now and it has definetly been the best watch I have ever had. I am not atheletic at all. I just love all the little things you can stick into a watch. Accessibility The buttons are large ...

Pros: Price, Durability, Accuracy.
Cons: Cosmetically inferior to other monitors. Uncomfortable watchband.

The Timex Ironman heart rate monitor is another great product in the Ironman line. The watch is extremely durable, (however, my Indiglo light died within a couple months), and accurate. The watch has all the features you would want, and Timex has...

Pros: Stopwatch functions
Cons: Electrical - signal transmissions problems

I hesitated to write a negative review until I tried a Polar HRM for comparison sake. I thought it could be me and my heart. Well it's not me and my heart. The Timex 50 lap HRM is just a crappy HRM.

The Heart rate displayed by the watch...

Pros: Excellent Value for the money! basic non-techno crap.
Cons: Resin band needs to be replaced with fastrap, resin is uncomfortable

I searched for many weeks before settling on this monitor. I spent a great deal of time determining ...

Pros: sensitive buttons, poor hrm signal capturing,poor software
Cons: Not too expensive

Bought from campmor.com about 2 years ago. HRM sometimes can't get the signal (new battery) Buttons are very sensitive, it is a real problem if you sleep with it. My watch has some software problems, sometimes it resets itself (all the time and date data) while I am trying to reset my chrono. I would not recommend it anyone. I will try fitsense or polar for the next time

Pros: Easy to read, versatile, durable, good timekeeping and battery life
Cons: wrist strap breaks, printed button writing wears off, day/month wrong way around for Oz

My Triathlon is the 50772 which I paid Au$100 for about 3 years back. It has worked well with no functional problems and is still on the same battery.

The writing on the buttons has almost worn off and I am on my 3rd wrist strap, but that aside it has worn well. I don't take it off so it goes in the shower, pool etc with no problems.

Getting a strap in Australia is 40% of the cost of the watch, that hurts as they don't go the distance.

Being able to change the month/day to day/month would be good.

Pros: Sharp looking, great features, accurate, adaptable.
Cons: Watch band durability is only weak link.

I LOVE this watch ... it's the only timepiece I've worn for YEARS. Use it 24/7, it's my alarm clock and sometimes even flashlight when trying to navigate in a dark room without waking up the Mrs! I've done many triathlons and that was my original motivation to buy the earlier version of this watch. I also fly military fighter aircraft and have taken this watch with me -- to help time low level routes or to meet a time on target. BUT ... the watch band ALWAYS dies well before the watch?! I've got now THREE still ticking watch heads from old watches. It would be nice to have replacement watch bands available so I don't have to by a new watch every time the band wears out.
