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!

Very nice, but sizing is inconsistent
Size: 10 Wide, Color: Ivory/White/British Tan
All of these Cole Haan shoes are extremely well made and I like the styling. On the other hand, the sizing is very inconsistent and you may end up having to do a lot of returns trying to find the right size. Then if you get a different color of it, you may find the sizing different yet again.
If you find your right zie, they are really nice shoes at a very reasonable price for the quality.

I love this brand. These shoes look and fit great!
Size: 13 Wide, Color: Black/White/Black
I love wearing Cole Haan shoes. This is the second pair I’ve owned and the style just gets me. I’ve worn these to work at a great professional job every day, not just casual Friday. I wear these when I head out shopping or to dinner. They are functional, comfortable, built for regular and bigger wider feet and comfortable. I am 6 feet tall and my feet have changed size over the years to me needing a wider shoe to relieve pressure on my toes and front wide porting of my foot. So the 13W feels great and still walks the same as a regular 14 but more comfort for me. They look amazing and qualify in some offices as dress shoes (depending on company rules they will justify a sneaker as a shoe with the tan colored “gum” sole as a sneaker) so check company policy. The black sole on this makes it look more dressy. I am switching out the laces to match my previous Cole Haan because I think the white shoelaces look better. As an adult, aside from my Kenneth Cole boots Reaction boots and Doc Marten’s these are the only shoes I will pay 3 digits for. This looks like skater shoes but with a more mature look.

I am certainly glad I found them and finally ordered
Size: 10, Color: Ivory/White/British Tan
A bit bulkier than my Stan Smiths Leather versions, but actually more comfortable.
They seem to be a bit "clunkier" looking than a streamline Stan Smith, but it's a matter of style. It works for a change of pace.
Gets or picks up dirt a bit, but cleans well, except the canvas part.
Has lasted almost 6-8 months with very little signs of wear.
Feels very secure in any type of weather or condition.
Great alternative or addition to having a pair of Stan Smiths.
