Types of ETA Watch Movements

ETA produces a wide variety of watch movements, catering to different needs within the horology industry. These movements are primarily categorized into mechanical (manual and automatic) and quartz types, each with distinct characteristics and applications.

Mechanical ETA movements are known for their craftsmanship and reliability, favored in traditional watchmaking. Automatic movements, a subset of mechanical, feature a self-winding mechanism powered by the motion of the wearer’s wrist. Manual mechanical movements require regular winding by hand to maintain operation.

Quartz movements, on the other hand, are battery-powered and known for their accuracy and low maintenance. ETA quartz calibers offer precision and affordability, making them popular in both luxury and everyday watches.

Key types of ETA movements include:

  • Mechanical Manual-Wind Movements: Require winding by hand; valued for their simplicity and tradition.
  • Mechanical Automatic Movements: Self-winding via rotor motion; combines convenience with mechanical craftsmanship.
  • Quartz Movements: Battery-operated; highly accurate and low maintenance.
  • Chronograph Movements: Available in mechanical and quartz versions; include stopwatch functions.

I’m Arron and I’ve always liked pulling things apart just to understand how they work. Watches were a natural obsession. Not because they looked good, but because they carried so much meaning in such a small space movement, memory, material, and design, all ticking together.

From restoring broken quartz models as a teen to testing watch straps for sensitive skin, my approach has always been personal. Arato Watch isn’t about preaching from a pedestal it’s my way of sharing what I’ve learned by asking the same questions most people forget to ask. I believe watches should be understood, not just worn. That’s exactly what this site is here to help you do.
