Yes and my husband and I both owned Swatches. We got them in 1988. I have two of them, actually. Because of my interest in Apple Watch, my interest in all of my watches was revived so I've been looking through my collection of watches that span 43 of my 48 years. My beautiful stainless steel Mickey Mouse watch with black faux leather band still runs and still looks beautiful. I got it in 1972 for my 5th birthday. It was very inexpensive but due to the materials it has stood the test of time, pardon the expression.
But those Swatches...they are disintegrating into dust!
My husband had dug his out a couple of months ago and said his band snapped into pieces. Mine hasn't broken but when I flexed the band fine dust billowed out from it. I tapped the case and it was very brittle and also crumbling into a powder that's nasty to breathe.
I do have a much older no-name all plastic acrylic body watch that seems to be just fine, though.
I don't know I just don't trust plastic for the long haul and I don't like the feel of plastic watches against my skin.
