Was wondering any best practices to remove some scratches on the case of my Venu2.

Here are some best practices to try and minimize their appearance:
Screen Protector: Applying a high-quality screen protector can help mask the scratches and prevent further damage.
Polishing Compound: Use a polishing compound specifically designed for watch screens. Apply a small amount to a microfiber cloth and gently rub the scratched area in a circular motion.
Baking Soda Paste: Mix baking soda with water to create a paste, then apply it to the scratch and gently rub with a soft cloth. Be cautious, as this method can sometimes make scratches worse.
