The crown unscrews to set the time and date and that's why you couldn't make it work you mook. I've got two...the white one is beautiful

Watch arrived within a week after ordering. Large face, rubber wristband....nice looking. Sits high on wrist which was a bit awkward. Big thing though...couldn't set the time as per printed instructions. Couldn't get the watchstem to pull-out to set date & time. It was frozen. So, I packed it & returned it.Would've kept it if it weren't for the malfunction. Rather than replace with another, I requested a refund.
