It includes a back remover for rotate-open cases and an anti-scratch film, which helps prevent cosmetic damage during battery changes or strap work.

JOREST Watch Battery Replacement Tool Kit (Rotary Opener)
This updated 2026 model from JOREST emphasizes a stronger case wrench designed to handle larger watches with grooved backs. It uses a rotatable back-opener with 1.7mm square claws and a wider range (19–59 mm). The kit is built to be more labor-saving and stable, which helps users open larger or more stubborn cases without excessive force. It suits those who frequently service bulkier luxury or sport watches.

JOREST Watch Battery Replacement Tool Kit (Grooved-Only)
This option targets a single back type for users with notched grooved round watches. The included watch holder helps apply torque safely, reducing the risk of scratches. Anti-slip films further protect the watch during operation. It’s a precise choice for round cases with notches rather than multiple case designs.
Best for: Owners of round watches with notches wanting a secure, scratch-protected opening experience.
Caution: Not suitable for pry-off, screw-fixed, or square-case backs; confirm your model before choosing.
Buying Guide: Key Considerations For Wrist Watch Case Openers
- Case back type compatibility: Rotating, grooved/notched backs, pry-off backs, and screw-fixed backs require different tools. Verify your watch back style before purchase.
- Tool range vs. use: If you only replace batteries, a compact, notched-back-compatible kit may be best. For strap resizing and more complex maintenance, consider a larger kit with multiple bits and a strap tool.
- Protection features: Anti-scratch films and watch holders protect the case during opening. These features are valuable for preserving finishes on valuable watches.
- Durability and materials: Steel and high-quality alloys increase tool life and reliability, especially for repeated use.
- Ease of use: Look for adjustable openers with clear wheel mechanisms and a comfortable grip. A well-documented manual helps beginners.
- Portability and storage: Larger kits with many components can be bulky. If space is a concern, prioritize compact sets with organized storage.
