Many years ago I found a Cassio watch with a silicone strap and I really liked it. I haven't been able to find another one until now and this new watch reminds me why I loved the old one so much. The silicone strap changed everything for me - every leather strap I've ever owned broke, lost lugs or wore out long before the watch itself wore out, and it was cheaper to just buy a new watch than an old one . change stripes. But the silicone lasts forever, doesn't irritate my skin and is very easy to apply. The clock itself is small (just under an inch) but the numbers are clear and easy to read. I have a small wrist so it fits me. I can see this working well for a child but not for adults with large wrists. Most watches seem huge to me, but this one is the perfect size. Super happy with my purchase!
