Aqua Terra 38 ... rubber band size.

Hello, I have an aqua Terra 38 with a leather band and deployment clasp. I have a 6.25" wrist and the band is very Slightly large for me at its smallest size. I wanted to switch to a rubber bracelet. Will the standard 19" rubber bracelet be too large for me as well?

Any insight into how much smaller the "small" version is this is?

Thanks!
