My last Timex and why.
Color: Black/Gray/Digital, Color: Black/Gray/Digital
New edit. Upon further reflection, I’ve only had, a couple of exploratory years with Swatch excepted, Timex watches. My first one was when my mother replaced the Chicita Banana “tickity tock” sticker with a real Timex wind up watch before my first Cub Scout camp. In addition to many other Timex products, I’ve had these Ironman watches for the past 25+years. Usually the band wears out and can’t be replaced after three or four years. This particular watch fell apart less than six weeks old. It wasn’t hit by impact. It just came apart while I was driving down the road. I wonder if they’ve changed their manufacturing process. See photo for details. What is truly infuriating is that rather than replacing it, because it is truly a warranty issue, the told me to ship it to their offshore repair facility (which could take 3-5 months) and pay what might be half the value of the watch. Things happen, but the intentional friction they have created to avoid their obligations borders on malpractice and speaks to their indifference toward customer experience and subsequent lifetime value.

As expected
Color: Gray/Gray/Digital
Just an old school digital timex. Tried and true. Has both 12hr and 24hr function on the time setting. Has a standard stop watch and timer. The battery is great, just as it always is on a timex. Good water resistance and very easy to use. Overall very good watch for the price!

I absolutely love these watches! They are built like a tank. They can take a lot of abuse and still keep great time. I originally was going to buy just one to replace my old watch. Ended up buying several of them. Great gifts. The watches are beautiful and elegant, and I feel like a thief when I buy them because the price is so low I think its a typo. I have gotten several compliments on them when I wear them. I have busted up concrete and cleared heavy terrain ,cleaning areas out, wipe then off and they look Like I just took them out of the box. The only thing, and it's not a big deal to me.But the glow in the dark arms don't last long. They even give you the tool to adjust the wristband. Who does that🤣 The Quality of these watches are phenomenal BUY ONE! You won't be disappointed.
