Types of ETA Watch Movements

ETA produces a wide range of watch movements, catering to different types of timepieces and horological needs. Their movements can be broadly classified into mechanical (manual and automatic) and quartz categories. Each type offers specific advantages and is chosen based on the watch’s design and functionality.

Mechanical Movements

Mechanical ETA movements are powered by a mainspring that needs to be wound either manually or automatically via wrist motion. These movements are prized for their craftsmanship, longevity, and traditional watchmaking appeal.

  • Manual-Wind Movements: Require regular winding by the wearer to maintain power. They are often thinner and allow for classic watch designs.
  • Automatic Movements: Feature a rotor that winds the mainspring using the wearer’s wrist movements, providing convenience and continuous operation without manual winding.

Quartz Movements

Quartz ETA movements use a battery and a quartz crystal oscillator to maintain timekeeping accuracy. These movements are known for their precision, low maintenance, and affordability.

  • Often used in everyday watches and fashion timepieces.
  • Can include additional functions such as chronographs and calendar complications without significant increases in size or cost.
