Tips - The wall clock movement is a high-quality electronic product, compatible only with carbon batteries. Please do not use high-capacity alkaline or rechargeable batteries, as this may reduce the movement's lifespan and timekeeping accuracy. Great Design - The wall clock frame is handcrafted from solid iron, and the high-quality materials ensure the Roman numeral wall clock's sturdiness and retro look. Vintage Decoration: This decorative wall clock is suitable for the living room, office, bedroom, kitchen, school, classroom, and other public or home spaces. Easy to Install: The hook design, while sturdy, won't damage the wall. The clock's slotted back makes it easy to hang and is powered by 1 AA battery (not included).
