It is rather in the toy! All pin punches are bent tips (and difficult to untwist), the pin extractor tool (the big blue thing) share in the piece to be touched! (But you can go back in? Manufacturing Lego) None of the tips only opens a Seiko, plus they have so much game that is sure to scratch the bottom of watches. In short, try to change the battery of a Swatch Like 30 euros, so why not? But I prefer to entrust a beautiful watch in my watch than the massacre with this toy! Moreover, received on time, well packaged, the Amazon button. Like many users I counted all the pieces: one is almost 30, but I'd rather solid 4 rooms 30 twisted.
