Love Time
Color: Pink, Color: Pink
I love this watch 😍 I usually get the smaller gray/black one. Though this one is A LOT bigger than I expected. Not remembering the size of my wrist, plus the old saying is ... Why do women have a hard time telling distance ? Because we were told this 🤏was six inches long 🤣. The color wasn't quite how I thought it would be either, so that through me off a bit. I love the colors & I have been wearing Timex Iron Man watches for 37 yrs. I will not wear anything else. They'll last for years. Once the battery dies, I just get a new one. I also wear mine almost 24/7. I discovered these when I was 18 & needed a good watch for work (food service) whitch take a lot of beating. What's the old saying ? Time takes a licking and keeps on ticking. It's so true!!! I did try a couple before my Timex Iron Man, yeah, Nope. Timex is the best !!

Reliable watch, bad shipping
Color: Pink
I have had a couple other Timex watches. My 1st lasted many years before it quit working. This watch is my 3rd. My 2nd Timex still works but was smaller than I prefer so I bought this one. I'd have given this one 5 stars if it had arrived on time and not had made my subscription order arrive late as well because my items ship to arrive on a set day. My auto ship happened to be when I ordered this watch. I was given a tracking # for USPS at first, to arrive on October 27. Then got notification it would arrive the 28th, THEN got an email saying November 2nd and coming by UPS. It arrived 4 days after it was supposed to. The watch is good, but the shipping was not.
