Eterna Watch Repair & Service

Eterna, a Swiss watchmaker founded in Grenchen, uses two kinds of movement: widely used ones from ETA, Sellita, Soprod and Ronda, and its own EMC calibers. That difference shapes service.

Eterna factory service

Eterna's movement manuals advise a full overhaul at least once every four years, with regular water-resistance checks by an Eterna authorized retailer or approved general agent. Its four US service centers are:

• Time Innovations Atelier, New York, New York
• West Coast Watch Service Center, Los Angeles, California
• Shami Fine Watchmaking, Fairfield, New Jersey
• Stoll & Co., Dayton, Ohio

Independent Eterna service

An ETA, Sellita or Soprod automatic is routine work for an experienced independent. For an EMC caliber, ask whether the watchmaker has serviced one and can get the parts.

Before you ship, ask

• Does my watch have an Eterna EMC caliber or a widely used movement?
• Have you serviced an Eterna, and can you get parts for it?
• Will you test water resistance after closing the case?
• Will I get a written estimate before work starts?
• Are you authorized by Eterna for service, and where does that show on Eterna's own website?
• Will the work be done on site, or sent elsewhere? If it is sent on, where does it go, and does the quote add a fee on top of the service center's charge?

Providers on this page were researched against our Standard at the time they were listed and are rechecked periodically. Details can change between checks, so confirm terms, pricing and turnaround directly with the provider before sending your watch.
