Mechanical Watches: These operate through intricate systems of gears and springs. They require manual winding (in the case of manual watches) or are automatically wound by the motion of the wearer's wrist (automatic watches). Mechanical watches are known for their craftsmanship and often considered a luxury item.

Quartz Watches: These use a battery to power a quartz crystal, which vibrates at a consistent frequency to keep time. Quartz watches are known for their accuracy, affordability, and low maintenance.

Smartwatches: These are digital watches that connect to smartphones and offer various functionalities beyond just timekeeping, such as fitness tracking, notifications, GPS, and even making phone calls. They often include touchscreens and can run apps.

Analog Watches: These traditional watches use hour and minute hands on a dial to display the time. They can be powered by mechanical or quartz movements.

Digital Watches: These display the time in numeric form, often using LED or LCD screens. They are typically powered by quartz movements.

Hybrid Watches: These combine traditional analog watch designs with some smart features like fitness tracking or notifications, but without a full touchscreen or extensive connectivity.
