Glass scratch sensitive

Have bought from original German jeweler for more than 500 euros. After 2 years bracelet without scratches as new. Closure without problems. However, already the 3rd glass there. Every approx 80 euros paid. The glass scratched once you offend only slightly. In my other brand watches price range 300 EUR for years not a scratch in the glass. For a clock in this price range that is unacceptable.
