Most of the clocks are battery powered and use AA alkaline batteries. Listings repeatedly note that batteries are required but not included; one description specifies it runs on a single AA battery.
Clock faces are most commonly white or off-white, with some options available in black or beige. Listings specifically mention white, off-white, black, and beige face colors.
The selection includes wall clocks designed to hang (many note a hanging hole or that they "hang like a picture") and tabletop/mantel/desk clocks with stands or pedestal bases for placement on flat surfaces.
Warranty lengths vary across the selection; listings show limited warranties of about 1 year, 2 years, and 5 years.
Listings reference quartz movement and silent/non-ticking mechanisms. One description highlights a quality quartz movement, while another specifically notes a silent, non-ticking mechanism.
