Ironman 100
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.

Perfect for Training (Swimming) Purposes.... 5 Star for what it does as a training watch!
This is already my 2nd TIMEX which I use for my swimming practices.. This one beats the older model (Timex 51931 Ironman Triathlon) with some interesting changes: 1) The larger digits on this model makes it easier to read the numbers (as some mentioned to do so when running) even when I am swimming, with a quick flick of the wrist at the turn, it's possible to see the minutes and the seconds.... The older model had smaller number, thus not making it possible to do this. 2) The navigation on this model became quite easier. It was already easy on the older model but this one included instructions on screen, such as NEXT, DONE, + or - in order to advance with your practices and training... Plus a chance to change the way you want to see the information of the your laps (Laps in the big digits and splits at the smaller one, or the oposite) A Real nice add on by TIMEX. 3) A simple but effective wrist band "clip" (the tiny piece of strap that attachs the "extra" wrist band that is left after you put the clock on) It has a piece of rubber on the inside that locks on at the wrist band and does not make it loose or even letting it go as some other watches do sometimes. This is more effective underwater I think, as it remains the way you set your wrist, as the older model I had did not quite held in place all the time. 4) Plenty of memory (100 laps is really a nice number), maybe more then most will need but, as a swimmer I use to count splits over 100m (or yards) with many laps during one training... It is quite usefull. I go easily on 10 to 15 laps of the memory in one training. And with the date feature, that reminds when you did these times, it is quite usefull to keep track on the training with a spreadsheet, for instance... (as I do !) 5) A really big START/SPLIT buttom that is great to press when I am swimming laps and have to press myself at each turn at the pool. Just perfect. Never a miss ! And the feature which was already at most of the models, of the repeat countdown, and the start of a chrono, or a repeat (what I use the most) in order race agains your average rhitym inside a certain time frame that you can set it up ! And of course the flix technology, which is very good to have it... Just flick your wrist (when you set it to ON) and it will show you at night all info that you need. It is another great watch from TIMEX and it deserves a look, specially for the price. It is worth to pay a bit more if you are like me and uses a lot of the memory for the laps on swimming pool. Maybe for runners it can be quite a lot of memory, but the price difference is worth the change, for some of the options mentioned at this review. This is a really good watch to have.. Will you definatelly like as we all are at these reviews. :-) It deserves the 5 stars rating !

clean big face; easy access features; light; effective
If you're looking for a light, easy to read watch that also has sport/triathlon features like chronometers, split times and lap timers this is a nice update on the classic timex ironman 100lap watch. Additional features: multiple alarms, two time zones, 12/24 hour settings, the memo feature of old seems to have been deleted and an "interval" feature added - can program in up to 9 segments of an interval and then chose whether intervals end after one go, or just repeat the set (woulda been nice to be able to set how many intervals you'd like to go through) I use the dual time zones quite a bit - it just makes moving between my two usual time zones literally a single button press. When using the alarms for travel, i've never missed a self-wakeup call - always reliable and sufficiently toneful to wake me up when i don't want to rely on myself to get up (that time zone change thing). Super go-to functional, multipurpose knife - rather the swiss army knife of watches for me. improvements: the button layout hasn't changed v.much in years - and that's a feature. What has changed in the right way is - the face - so easy to read at a glance - nice if moving in particular the indiglo lighting has improved dramatically for quick checks when it's dark. The alarm chime, also better - no longer a beep only -it is a sort of chime. The strap feels better - and i can see there are replacements online - though i haven't had to replace the band on my last timex ironman from when i changed it at least 3-4 years ago - so perhaps they've just gotten better. strap has a nice feature to keep the tail of the band close to the strap, too. This is a refresh i've been keen to see as i do like this classic layout/feel. The price at amazon also made the decision to refresh the face of this watch a much easier decision(the ironman i have is about 10 years old - it's fine ) hope this helps you if you're thinking about this watch

Timex Ironman 100 Lap Flix System Watch
I had a Ironman Datalink, where you could zap phone numbers on to your watch from your monitor with a series of blinking lights. Awesome watch and stood up to over 10 years of use. Just recently started reseting when using stop watch. So I came here looking for the same, but slightly different (as the Datalink software is out of date). I found this one, Pros. works great just like the old one. Indiglo is different but better on battery life. The ability to Flcik your wrist to turn on the light is pretty cool. Cons. Nothing that should stop anyone from buying it, it is all personal preference. When cycling through the funtions on old watch it made a different sound when you were back at the beginning. The Stop watch, timer, alarm are not as easy to use and manuever as the older version. The light function, you have to turn on the option, and then it only last like 8 hrs... So basically instead of fliking my wrist to see the time, I flick realize it has been more than 8 hrs have to push the button anyway... Now that was the same and only con I had with the older model. Oh and I may replace the band with a cloth band, the hard plastic one that comes with it is comfortable enough, but it can start to dig.. Other than that fine watch.

Experienced just as advertised - fits snugly on wrist. Features easy to understand and apply. Light is good. Large digits great for eyes not as sharp as they used to be!!!!!! So far, so good - the real test is always time ! Godd value for my needs.

Great watch: easy to see the numbers on the display. Simple set-up and robust. I have had this model for the last 18 years and will continue. The only issue can be that afterbattery exchange it may lose waterproof, to avoid that ask only the proffs to exchange the battery!
