In the case of my clock pin receiving the bracelet was initially lower than the pusher. So you should make sure that the hole in the strap with the pusher on a plane. For height compensation, I fed the bracelet just with Pappschnipseln from the Amazon package. To aim a good lighting or daylight should be used. The threads of both components (lacquered Aluklotz and recording of Ausdrückers) is very rough and thus has a lot of play on. A finer thread would not so much game, but also carries the risk that the steel threads of the screw will damage the aluminum thread with excessive stress. The bracelet pins soft the great power that can be transmitted via the thread, effortlessly and easily push out. If this is not the case, the pusher is located on the bracelet, not the pen! Then please stop immediately, turn back the screw and re-center. Otherwise there is a danger to bend the pusher! When working on watches sensitivity should prevail!
