Take licking and keeps on ticking

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.
