Can I tighten this?

[Masteryacht]

My bracelet is in fine condition and doesn't need service, but my fliplock just doesn't have much tightness left when closing or when it's closed. It has never come open on it's own, but there isn't much friction between the little outdents and the clasp. Is there an easy way to tighten this?
Man, these older clasps really aren't worthy of such an expensive timepiece.
