I've a WJean dlc mesh and the only adjustment is by removing links and/or the spring bar at the clasp. I felt that the clasp was a bit cheap and nasty: it only has three adjustment holes and it wouldn't close in one of the positions so I was unable to get a good fit. I was going to send it back for a refund but decided to try it with a new clasp from strapcode.com and now its perfect. Check out the Strapcode site as its Hong Kong based but the clasp I purchased shipped from the UK and arrived in a couple of days. I've also heard that the Strapcode and WJean bracelets come from the same factory but I can't confirm this.
