Adjustable Watch Case Opener with Pins

This threeprong case wrench is adjustable to fit a range of case diameters and slot patterns. The sliding head allows you to position the hardened pins so they sit in the case slots, and the textured handle helps you hold the tool while turning. It is suitable for battery changes and other routine maintenance on many screwdown casebacks.

As with any openjaw case tool, care is required to avoid slipping and scratching the metal. It is a sensible option for hobby use or occasional bench work; professionallevel wrenches will give a finer fit and greater durability.
