What is a caseback in a watch?

Vaer Watches Updated by Vaer Watches

The caseback of a watch refers to the removable underside or back of the watch case. The caseback is typically removable for the purpose of service or regulation.

The caseback is the part of the watch that protects the movement, and on mechanical watches, provides a glimpse into the intricate mechanics and artistry behind its functionality.

The primary purpose of the watch caseback is to seal and protect the internal components of the watch from dust, moisture, and other external elements. It ensures the longevity and durability of the timepiece, safeguarding its precision and performance.

Typically there are two styles of caseback:

  1. Solid Caseback: an opaque plate that fully covers the movement and attaches to the rest of the case. It provides a blank canvas for various engravings, such as brand logos, serial numbers, or intricate designs, adding a personalized touch and enhancing the exclusivity of the timepiece.
  2. Exhibition Caseback: a transparent back that allows a view of the watch's movement. It often features a sapphire crystal, offering a clear window to admire the intricate inner workings of the watch. An exhibition caseback provides a captivating and educational experience, showcasing the craftsmanship and artistry involved in creating the timepiece.

The materials used for watch casebacks can vary, depending on the design, functionality, and desired aesthetics of the timepiece. Common materials include stainless steel, titanium, ceramic, and precious metals like gold or platinum.

For durable outdoor watches, like those built by Vaer, quality machining, threaded screwdown functionality, and thick durable rubber gaskets are all essential ingredients to deliver impressive water resistance capability at the watch's caseback.

Along with the crown, the caseback is one of the most vulnerable points of a watch when it comes to risk of flooding, and these premium durability features are important to deliver a rating of 10ATM and beyond.
