A hand-and-dial clock is chosen by how it reads from across the room, so start with dial diameter and contrast.
- Face size in inches relative to viewing distance, since a 12-inch dial stays legible from roughly twenty feet away.
- Movement type, because a sweep quartz mechanism runs silently while a stepping second hand produces an audible tick.
- Mounting and power details: keyhole slot or bracket on the back, plus the battery size the movement takes.
Glass or acrylic covers change glare and cleaning, so check which one a listing uses before hanging it opposite a window.
