Cleaning
- To clean the glass surface, use a soft, dry, lint-free cloth. For stubborn marks, a slightly damp cloth with a mild glass cleaner can be used, followed by drying with a clean, dry cloth.
- Important: Avoid touching the clock hands directly during cleaning, as they are delicate and can be bent or damaged.
- Do not use abrasive cleaners or solvents, as these can damage the clock's finish.
