Hello! I speak Spanish so I'll try to explain myself as best I can. Since Saturday (the day I really noticed) my watch has had these "dark spots" that aren't very visible during the day, but are visible at night. For a moment I thought I had gotten it dirty, but the stains never came out of my watch. Does anyone know what I can do? Or what happened? Will more appear? :( I have the watch because it was a gift from someone close to me; I don't want it to get ruined.

As extra info, during the day as I mentioned they are not seen and are not a nuisance, only at night they are.

Attached are 2 photos; photo 1 is from the daytime and photo 2 is from the nighttime. :(
