The clasp on my steel watchband pulls away from the band creating a large gap. it looks bad and catches on things. what do i do?

You need to make sure that if you had the watch band adjusted they did not adjust it at the clasp. When you adjust the watchband links should be removed if you adjust it at the clasp the band keeps pulling open. When you open the clasp fully make sure the pins are on the end holes. If the pins are in the end holes then, the clasp is probably sprung somehow and you will need a new one or have a jeweler or watch repairman fix it! You may also be able to order a new clasp from manufacturer! Hope this helps!!
