Many have complained about the clasp on Skagen watches.  This video illustrates a helpful way to secure the clasp in order to prevent accidentally dropping the watch due to insufficiently closing the clasp.

Just sing, "Hook, snap, and snap" each time you put on your Skagen watch. That is, first attach the hook end of the clasp to the other end which has the horizontal pin (the pin at the bottom part), then snap, fold down and close the clasp, and then snap a second time.  Once you have performed "hook, snap, and snap" successfully, your clasp is now sufficiently secure.

Hope this helps! :)
