Great Multi-Function Watch
Color: Gray/Digital/Gray
I absolutely love my Timex Ironman watches. I have had many over a very long period of time.
Wonderful set of functions for the price.
Very affordable.
Easy to use. Lasts a long time. Very easy to read in standard lighting. I like the Indiglo when needed, but do not use it too often.
Absolutely love the ability to set a repeat timer to remind me to do something at a fixed interval, or to keep me on task for a fixed period of time.
Great to be able to set three independent alarms.
Potential to capture a huge number of splits with the stopwatch.
I purchased this watch to replace a similar model with a dead battery. I have replaced batteries in the past, but it is quicker and easier to buy a replacement watch. I am saving my old watches for that day in the future when the Ironman model may no longer be available. I expect this will be my watch of choice for the rest of my life.

Just fine if you have simple needs...
Color: Black/Digital/Black/Green
Exactly what I needed: a cheap, durable wrist watch. The only thing it was lacking were instructions, but about 5 minutes of messing with the buttons got it set up

Compared to g-shock?
Color: Black/Yellow
Firstly random public reviews can be comical…”it’s has a battery, terrible, One star” or “I don’t like yellow, one star” omg peoples do better. I’ll review this while comparing to an older style of g-shock from the same era. I’ll start by saying this timex rocks, for me in my mid 50’s it’s so retro and nastalgic, brings back memories, I may have even owned this model back in the day. What’s great about it- the display, larger digits than the typical g-shock and they are super crisp, clear and easy to read. The indiglo is awesome. This is the most accurate quartz watch I have aside from the atomic g-shocks that adjust themselves daily. I prefer a chunky watch and the g-shocks do a better job in that department. i feel this watch is rugged, but I’d still give the nod to g-shock in this department. 200M water resistance is the gold standard and this watch has it which I love for peace of mind for any water based activities. This is a 5 star watch at a great price. I still love some aspects of a g-shock better but its just preference.

Everybody loved the high-tech style and amazing functionality
Color: Black/Yellow
I'm not a Timex fanboy, and I've had my fair share of problems with the Expedition line, so this review is my honest opinion as a man who's worn Armitrons and Timexes since I was 10.
I remember in 1992 when the Timex Ironman Triathlon with Indiglo was first launched - My older brother got one, then me and my neighbor friends. Everybody loved the high-tech style and amazing functionality. Even Bill Clinton was rock'n this watch, for those who don't remember.
Quite simply, this is the perfect watch at a great price, in my opinion. Perfect as a gift for any man, and I think the original black/olive drab/yellow coloration is still the coolest. In this day and age of smartphones, it still pays to have this watch. The alarm is less annoying sounding than a cellphone, and doesn't wake up the entire house. To turn it off, just tap the watch, no more reaching for the phone or alarm clock. Timer comes in handy for anything; timing my kids' timeouts when they get in trouble, 15 minutes room clean-up times, etc. Chrono is fun for anything you wanna use a stop-watch for. I set the second time zone for Vietnam time. It really is a million times easier to use this watch for all of its functions than reaching for a smartphone or alarm clock, etc. If you;ve been relying on your phone for a few years as a watch/chronograph/timer/alarm - you'll be so glad you finally got a watch like this.
I've never tried a smart-watch, however I feel those are not as necessary,durable or practical as a real watch. Other Timex watches I've used were freakin' trash - couldn't throw em away fast enough. Might as well open the box while holding it over a trash can, so the watch can fall right in when you open the box. That's my experience with the Expedition line-up.
Back to this watch: The only thing I wish this watch could do is measure activity thermogenesis (calories expended throught the day) or work as a pedometer, which some smart-watches and other devices can do. I also cannott decide if I like this new, slightly larger, heavier/thicker design of the Ironman Triathlon over the 1990s design. The 90s models styling was "tight to death'. Star-split buttons were seperated. The mode button was yellow. Overall more compact and bi-cultural;by that I mean it looked great as an athletic watch or a politician, business man wathc. This new model is bigger, better ingress/shock resistance, and more of an athletic style over all, and is a little less colorful.
I almost went with the G-shocks, but they still just look like crap and are waay to expensive. Sure, they have some better features, can survive WWIII, but I am a traveler. I need a watch that can work in the dark in any environment. The G-shocks are often using some kind of solar battery crap and rely on cathing a signal from an American automic clock in Colorado - good luck with that while your in Thailand on vacation.
