I try to put as much detail in the description as I can but some days I don't feel well and do a poor job. I am so sorry. Thanks for asking. The chain is 20" (a lot of people like to switch it out anyway). The bracelets usually run about 10" long but can be adjusted to a very small size. The faces are about an inch or 30mm wide, but the inside is a bit smaller as you can see from the photo. Thanks so much for your question I appreciate it.
