The problem which was often addressed here with the bracelet I can only confirm. The fortunately I have the right tools at home. When the strap cut make absolutely sure that the pull out of the pen a little sleeve fall out. Which is so small that it is hardly noticeable. The sleeve must be absolutely reinstated otherwise the pen does not hold, and thus fall out.
The booklet with the description is so small that you need a magnifying glass written to read it.
Otherwise, the clock is easy to use and you can not go wrong.
