Well thought-out features. Hopeful that the seals hold on this newer variant of the Classic 100.
Color: Black/Green
6 years ago, I tried my first variant of the Classic 100. The features were mostly, as expected, but the unit failed a short while into usage. This was disappointing, because the classic 50 had been a reliable goto until my last classic 50 started to fail this month. The current classic 100 variant arrived in a damaged box, but the watch appeared to have no physical damage. All functions operated as expected, save for the audible alarms, and beeps. Amazon/Timex offered to discount or replace. As I need the audibles for specific workouts, and daily meds, I opted for the replacement. I'm a day into the replacement and am very satisfied with the purchase. So far, it exceeds the classic 50 in many functions, but I am still partial to the button feel of the older unit. I've made it through a swim workout with no adverse performance. I'm hopeful that the current variant proves to have more reliable seals than the earlier model that I tried. If so, this is a worthy upgrade to the classic 50. ****************************************************************************************************************************** (Details from 2020 purchase) Over the last 15 years, I've purchased several ironman watches for a variety of workouts and incorporation into timed/scheduled home and work activities. Until this 100-lap model, all others worked great and continued to work well beyond the band failure (yeah, count on it) after 3 or 4 years. For this model, the indiglo stopped working within 3 months and now, 11 months in, the watch has fully reset 3 times unprompted during the past 2 weeks. This is fairly aggravating since it made me late for an appt on one failure and on another wiped out a number of workouts that I was tracking for an upcoming tri. Visibly, the watch looks new, no marks, no apparent moisture, but it has now proven itself to be thoroughly unreliable. This is very sad, because I found multiple uses for each of the features included in this model, and I had even adjusted to operating the very stiff split and stop buttons during swim/bike/run sessions. I gave this model 3 stars on water resistance, because I have no evidence either way as to whether this or the stiff buttons had anything to do with its failure. I'm going back to the 50-lap version. If I see a hint of non-band related problems with that, I'll have to assume that Timex is no longer in the business of making ironman watches for athletes.

Ironman 100
Color: Black/Green
Great watch, as a trainer it has everything you need if you don’t want to be distracted with notifications. Best part is the interval timers & stop watch. It did come with the indiglo button rolling around in the box… I popped it back on and it seems secure now… we’ll see. I have 2 Ironman 30’s and they are awesome as well… just doesn’t have the interval timer like the 100 series.

great watch for distance running, or any time you need a timer, alarm, or just the time of day
Color: Black/Yellow
I bought my first one of these shortly before running my first marathon, so that I could keep good track of my pace. Now in addition to race days it is an essential training tool for me. I check where the mile points are before going for a long run and check on my pacing. It's also great for interval training. The display is easy to read and the various buttons and functions are easy to figure out and use. I travel a lot internationally, and it has also become a great casual travel watch. The 2nd time zone setting is helpful, and especially being able to set a quick alarm has prevented me from accidentally missing a flight because I dozed off in the airport lounge. This is my 2nd time buying the exact same model. The battery on the first one died after almost exactly two years. I knew I could send it back to Timex for a new battery for $10, but I had a half-marathon coming up in a few days and wouldn't get it back in time, so I went to a local watch/jewelry place instead. They replaced the battery for $5 and it worked fine, but I don't think they got the waterproof seal re-inserted correctly, because when I got caught in a downpour the watch stopped working*. With another race coming up I searched the available options for new watches, and this is still the best model for my needs. One thing I will do differently is send the watch to Timex when the battery dies, as I expect they'll do a better job re-seating the waterproof seal. I got a prepaid mailer box from my local running store. *I put the soaked watch in a ziplock bag with some white rice and a dessicant packet. After a couple days (changing to fresh rice once a day) the watch display re-appeared just like new. In fact, it was only the display that stopped working, because it was still showing the correct time and had my mile split times up to the point it got soaked. I still wouldn't trust it around water, and I was going to keep it as a backup "dry weather" watch, but then my teenage asked for it so I gave it to him.

solid no nonsense watch
Color: Black/Yellow
This watch has many key features I needed in an everyday watch. - 5 separate alarms which you can set to a single day of week, weekend, weekday, or all week. useful for let's say trash day reminders or school day pickup reminders. The flexibility of the alarms is really key. - 9 interval countdown timers (repeats when done) - 1 countdown timer - stopwatch100 lap (more than enough) - indigo light, excellent nighttime illumination - excellent water resistance and durability. i've had mine for nearly 2 years and it still looks sharp. some of the lettering on the front has rubbed off, but most still visible, colors hold well. and i've put mine thru all sorts of abuse over the years. - large screen and digits for easy viewing at work. i have to record times at work so this was key. date and day of week is easily visible as well. - good battery life. if you don't use light a lot but use alarms regularly can last easily between 1-2 years - excellent price for about 30$ CONS: - no vibration, but i don't really need this - dual time zone... actually not ideal because you switch by pushing & holding the start/split button below the face. i accidentally seem to push and hold this button a lot thus it switches my timezone. i've gotten around this by just setting both times to be identical but a bit of a pain - resin band is durable but as always the little moving strap part to tuck away extra band breaks after a while. I discovered a neat trick to use my daughter's small hairband tie folded over twice to secure the extra band now. durable and doesn't look bad (if you pick the right color). - pain in the butt to change the battery (uses CR 2025 by the way). you have to remove both resin band parts first as it slightly overlaps the back case. then there are 4 tiny screws. once the bands are taken off it's pretty straight forward. make sure to align the thin rubber seal before you put the cover on. mine leaked water in after a change until I realized the seal was not sitting properly. Overall, I've been thru smartwatches, fancy watches, solar watches, ... mainly many casio and timex watches. this is by far one of the most practical and best watches I have. I'll be curious to see what google/apple create in the smartwatch category of the years.

Great sports/fitness watch
Color: Black/Yellow
I will start my review with an admission: I hate digital watches. I think 7-segment numbers look ugly, and I prefer the ability to see the 'distance' between times visually that you get with an analog face. But I needed the timer and lap counter for my job, and I have always wanted to do interval training to improve my speed and endurance while cycling. This watch had everything I needed and more. I was aware that Timex was a respected brand, and the T5E231 was the only watch in my price range with the ability to count 199 laps. I have to say, though, that after a week of use, I actually love this watch. Not only does it meet my needs functionally, but it actually brings me pleasure to wear it and operate it. The yellow trim around the inside of the bezel clearly identifies it as a sport watch, yet it seems to fit in well in formal settings. The interface is incredibly user-friendly and satisfying to operate. I never thought I would refer to a watch's "interface", but this watch actually has one. Pressing most of the buttons results in actual text being displayed on the screen telling you what the button did, or what will happen if you hold that button down just a little longer. In most modes there are even little labels that appear on the screen by the buttons telling you what they do in that mode. Figuring out how to use almost all of the functions only required five minutes of random experimentation. The only thing I had to consult the manual about was how to switch the chronograph into lap counter mode. I just wish there instructions explaining how to fold the manual back into a size that fits inside the watch stand. There are so many little touches that make it clear the designers at Timex really take pride in their work. Here are my favorites: -When turning night mode on, the Indiglo lingers for another few seconds after releasing the button. But when turning it off, the light extinguishes immediately! It should, since if you are turning night mode off, it's probably daytime and you don't need the Indiglo anymore. -Being able to scroll numbers backwards and forwards while setting times. On other watches it is so frustrating to 'miss' the number you want and have to press the button 60 more times. -Little icons appear on the home screen letting you know if the timer, chronograph, or alarm is running in the background. Most watches only have an icon for the alarm. -The speaker plays a different sound for the alarm and the timer, so you know which one is going off without looking at the screen. Also the Indiglo light flashes. -The Indiglo system is clearly a masterwork of engineering. It looks evenly lit and is very easy to read, yet it doesn't illuminate anything other than the display (unlike the backlight on a phone, for example). This must save a lot of battery power, since lighting up other objects around the watch is a waste of electricity. Besides, you have your phone for that! -In timer mode, you can see what time the timer was originally set for on another line below the countdown. -The AM and PM appear in the same place on the display; there is just one little segment that lights up to turn the P into an A. -Many of the buttons that perform an irreversible or potentially unwanted function (such as resetting the chrono or clearing workout data) require being held down for several seconds so you don't trigger them accidentally. -The watch tells you how much memory is free for storing workouts. There is only one problematic thing about this watch (and it may actually be a problematic thing about myself). In order to activate the FLIX system I am required to wrench my arm so hard I nearly dislocate it. It is painful, and takes way more effort than just pressing the Indiglo button. This doesn't bother me, because I didn't buy this watch with the intention to ever use FLIX, but it is somewhat frustrating that it is so hard to use. However, it is possible that my technique is flawed, and there is an easier movement that will activate it. But I don't really want to experiment; I like my arm in its current uninjured state. In all, I am very satisfied with my purchase. I love everything it does, and the only 'negative' probably says more about me than it does about the watch. Considering my abhorrence of digital watches, I am surprised that I like this one so much. I don't plan to wear it any other time than while at work or working out, but for those times it is not only tolerable, but actually enjoyable. I highly recommend this watch!
