What is a Watch Caseback?

A watch caseback is more than just a protective cover for your watch’s internals; it’s a window into the craftsmanship and engineering that goes into each watch. In this guide, we’ll explore the different types, materials, and features of watch casebacks.

The caseback is the rear cover of a watch that seals the case, protecting the movement and internal components from dust, moisture, and impact.

Types of Casebacks

Snap-On Casebacks

These are the simplest type of casebacks, often found in budget and vintage watches. For example, the Omega Seamaster 30 from the 1960s often features a snap-on caseback.

Screw-Down Casebacks

Common in dive watches, these casebacks are screwed into place, offering superior water resistance. The Rolex Submariner is a prime example of a watch with a screw-down caseback.


Exhibition Casebacks

Made of transparent materials like sapphire crystal, these casebacks allow you to see the watch’s movement in action. The Patek Philippe Calatrava often features an exhibition caseback.


Transparent Casebacks

A subset of exhibition casebacks, transparent casebacks are usually made of sapphire crystal and offer a full view of the movement, rotor, and other internal components. The Jaeger-LeCoultre Reverso is known for its transparent casebacks that showcase its intricate movement.

Engraved Casebacks

These feature intricate engravings or inscriptions, often for commemorative or limited-edition watches. The Audemars Piguet Royal Oak often comes with engraved casebacks for special editions.

Materials Used in Casebacks

  1. Stainless Steel: Durable and corrosion-resistant.
  2. Titanium: Lighter than steel but equally durable.
  3. Sapphire Crystal: For exhibition casebacks, offering a clear view of the movement.
  4. Gold: Used in luxury watches, adds a touch of elegance.

Maintenance Tips for Casebacks

  1. Regular Cleaning: Use a soft cloth to wipe away fingerprints and smudges.
  2. Seal Inspection: Ensure the seal is intact to maintain water resistance.
  3. Professional Service: Have the caseback checked during your regular service.
