I just received my 5167a Saturday, and sized it in around fifteen minutes. I found that a set of high quality scissors made it much easier than a utility knife or razor blade. I was shocked at how long the uncut strap is! I found it quite easy to adjust, just be methodical and take your time, removing sections one at a time from each side. I have mine fairly loose so it will move past my wrist bone without much effort, and the shape of the strap still keeps the watch stable and centered. I don't think there's anything wrong with the way the strap is adjusted, and it allows a precise fit with a little effort, without the excess strap that is sometimes a problem for those with smaller wrists, particularly with some deployant clasps.
