Automatic

Self-winding mechanical — powered by your wrist motion, no battery. The enthusiast default: a sweeping seconds hand and a lifetime with service.

Battery-powered, accurate to seconds-per-month, low-maintenance and usually cheaper. Ticks once per second.

Quartz accuracy with no battery changes — light keeps it charged (Citizen Eco-Drive, Seiko Solar, Casio Tough Solar).

Mechanical with no rotor — you wind it daily. Thinner cases, a deliberate ritual.

Quartz timekeeping with a mechanical chronograph module — crisp snappy chrono resets at a quartz price.
