Great watch - Nice large display!!
After my old Timex Ironman finally died after 21 years of reliable service (may it rest in peace after 4 replacement bands and 5 replacement batteries!!), I decided Timex deserved another sale from me! So I went surfing on the Timex website. So many Timex Ironman watches to choose from! But this one stood out for two reasons. 1) It has a nice simple design without a lot of "noise". 2) A nice large readable display. So I took the plunge! Indeed, Timex has definitely improved on their Ironman watches in the last 21 years. Most notably, the Indiglo light has greatly improved. It used to just light up the background. Now, it brightly lights up the actual digits which makes it undeniably readable without any eye strain. Another great improvement are in the set features. While the older models could only be set forward (in other words, if you went past your set point, you would need to go all the way around), this model lets you set forward and backward (so if you go too far, you can step back without going around). I don't understand one of the reviewers saying that the watch is too small. The face is quite large. The band may seem narrow in proportion to the watch face, but not excessively so. The band is 19mm wide and fits me just fine. Highly recommended!!

Like it so far after 2 weeks of swimming.
Like it so far after 2 weeks of swimming. Have been careful nio to press buttons underwater. I Like the large numerals, backlight, countdown timer, stopwatch and alarm. My last Timex 1440 lasted 10 years before the battery was low enough that the backlight was too weak to see at night. I replaced the battery on it but did not seal the o ring well enough with silicon grease so it leaked and quit working. I also had also replaced the band once.

Little Small On The Wrist
Really cool timepiece, been loving timex a lot recently, this is me coming over Casio/G-shocks. Although it is a bit smaller on the wrist it still looks very nice and I really love the gray and like green color contrast. Really easy to read the time as well.

Sturdy and digital
This watch has “ fake screws” holding the band on . The band is actually held on by the usual pins holding it on most watches but weaker . The pin came off while I was putting it on for the first time! This is the second time I bought off Amazon in 2 weeks where the watch appeared to be sturdy and the pins fell off . Going back to military watches that have material straps that go completely around wrist and do not have pressure on pins
