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.
