Paint chipping on space grey Apple watch

I purchased a space grey Apple Watch 3 three months ago. I recently found a spot that the paint seems to have chipped off right above the screen. My watch has always been in a julk protective case since day one and I have been very careful with my actions since owning this expensive watch. This is truly unfortunate since there is no physical or water damage to it. I know this is still under warranty and wondering if this watch can be replaced.
