The clock is really good, also fits perfectly on a slightly narrower arm, only the strap is really an impertinence. War with the clock at two (!!!) clockmaker who first had the strap cut on one side, at the other went nothing more, but he has his tools ruined, then referred me to CASIO. Bin then sold at one of the well CASIO models, but even he could not have the pins more than a few millimeters out knocking. Have then returned the clock, the hope in the second clock works with the uhrbandkürzen. Just nice and slow I all watchmakers through in my vicinity ........... Addendum to my review ... just came back from watchmaker and have at the clock newly obtained (thanks to Amazon for quick, problem-free delivery) can cut the strap that was done in a few minutes (4 euros) and no problem at all represented , either has been changed in the new supply something on tape or I have really bad luck and caught a defective strap. so there is of me now the full points for the clock. only the fine adjustment of the tape could be better.
