I have a very small wrist and this fits nicely.  I had to add an addition hole in the band since the band was too long.
The case of the watch is actually polish and not brushed metal.  From the photo, it looks like a brushed metal.
At first it was hard figuring out how to use the strap and buckle system.  After playing around with it, I love it.
The band is 19mm at the lugs and around 18mm at the buckle.
Since I'm not a big fan of polish metal look (looks cheap) I took some emery cloth and "brushed" all the polish parts.  This includes the clasp/buckle, case, lugs, and bezel of watch.  Now it looks like the photo you see.  Looks more "expensive" now.
For the price of the watch, Amazon had the best price.
