Keeps ok time, just ok, you can regulate it, but I don't wear it enough to justify doing that. **Q: Honestly how good is this watch, a good automatic watch for 20 dollars is unheard of** A: It’s awesome for 20.00 **Q: Is the bracelet hollow?** A: Yes, the bracelet is hollow. **Q: How easy is it to remove links?** A: I don't know, I removed the entire band and replaced it with a leather strap. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Nice watch nice price *by D***S on 12 March 2018* Nice watch.
