The Ironman logo is a serious distraction.
Color: Black/Black/Digital Neg Display
A wonderful watch, with one serious problem: for me at least. The big Ironman Logo at 9 O'clock position is a very confusing element in this otherwise nice design: it competes and completely overwhelms the two Hands read-out. The Logo can give you misleading time: because one confuses it for the Minutes Hand. In a hurry, one is bound to make such mistakes -- call it a human error, but this one can have serious consequences, i.e. reading the wrong time. I have a couple of digital Ironman watches, and Timex does a great job with their usability and quality. This watch is of very high quality too. I love the dual display, and it is very practical. All this watch needs is a removal of the white Ironman logo. That would also make reading the digital readout easier. Please leave the Minute and Hour hand to their exact shape/design -- i.e. don't mess it up. This watch has the potential to be a much more user-friendly watch. I hope the next gen has a simple dial with hopefully even an easier digital readout. Please color the 'Start' Button Orange. I love the Orange Seconds hand. Overall: Size is good. Strap is good. A very good concept digi-ana. Very practical.

Lemon
Color: Red/Black/Digital
I love the watch design, but the watch itself is a complete lemon. I have bought this watch three separate times and it still does not work properly. The first time, the hour and minute hand swung freely in the watch. I returned it directly to Timex. The second time, I bought from Amazon thinking the first watch had defect and the return policy with Amazon is less cumbersome than Timex. Right out of the box, I set the date/time and played around with the features of the watch that I most commonly use, most the chrono function. When I press start on the chrono function, the watch completely blacks out and resets itself somehow, meaning I have to set the date/time again. I sent the watch back to Amazon for a replacement. When the new watch arrived...same issue...the watch resets itself every time I start the chrono function. Very disappointing. Come on, Timex. You are better than this.

Unfortunate
Color: Black/Black/Digital Neg Display
It’s a cool new design but the night light button stopped working within a month of buying it. Shouldn’t happen with a 150$ sports watch

Garbage
Color: Black/Black/Digital Neg Display
Absolute garbage. The date that came up was from 2022. Most buttons did not work. Once you got into changing the time, etc, the watch locked up and would not get out of 'timer' mode. The watch lost 10 minutes in three hours. Do not purchase.
