Tools Needed for Opening a Citizen Watch

Before attempting to open a Citizen watch, it’s essential to gather the right tools to ensure the process goes smoothly and to prevent damage. Citizen watches often have various case back designs, so having a versatile toolkit is highly recommended.

  • Case Back Opener: Depending on the watch, this could be a case knife for snap-backs or a specialized wrench for screw-down backs.
  • Watch Holder: Stabilizes the watch during opening, minimizing the risk of slips.
  • Tweezers: Useful for handling small components inside the watch.
  • Magnifying Glass or Loupe: Helps in closely inspecting the watch mechanism.
  • Soft Cloth or Pad: Protects the watch crystal and case from scratches.
  • Screwdrivers: Precision screwdrivers, typically flat-head or Phillips, depending on the model.
  • Dust Blower: Removes dust particles without touching the movement.

Having these tools prepared will make the process safer and more efficient, especially when dealing with delicate internal parts.

Opening Different Types of Citizen Watch Case Backs

Citizen watches generally feature three common types of case backs, each requiring a different opening method:

  • Snap-on Case Back
  • Screw-down Case Back
  • Screw-in Case Back with Notches
Case Back Type Description Opening Method Common Tools
Snap-on Thin metal back held by pressure Use a case knife to gently pry open Case knife, soft cloth
Screw-down Back screws into the case threads Use a case wrench to unscrew counterclockwise Adjustable case wrench, watch holder
Screw-in with Notches Back with multiple small notches for grip Align wrench pins with notches and turn Pin wrench, watch holder

For snap-on backs, carefully insert the case knife’s blade into the small gap between the case back and watch case. Apply gentle leverage to pop the back open without bending or damaging the metal.

Screw-down backs require an adjustable case wrench that fits the grooves or notches on the back. Secure the watch in the holder to avoid slipping and turn the wrench counterclockwise to unscrew.

Some Citizen watches feature screw-in backs with specific notch patterns. These necessitate a pin wrench where pins align with the notches, allowing for controlled opening.

Handling the Watch Movement and Battery Replacement

Once the case back is removed, proceed with caution, especially around the watch movement and battery compartment. Citizen watches may utilize various movement types such as quartz, Eco-Drive, or mechanical, each with specific considerations.

  • Avoid touching the movement with bare fingers to prevent moisture or oil contamination.
  • Use plastic or non-metallic tweezers when handling the battery.
  • Note the battery model and orientation before removal to ensure proper replacement.
  • For Eco-Drive models, the battery is rechargeable; replacing it might require authorized service depending on the model.

If replacing the battery:

  • Gently remove the battery retaining clip or cover, if present.
  • Lift out the old battery carefully.
  • Insert the new battery in the exact orientation.
  • Confirm the watch starts running before closing the case back.

Properly Sealing the Watch After Opening

After completing any internal work, resealing the watch correctly is vital to maintain water resistance and protect internal components.

  • Clean the case back and gasket to remove any dust or debris.
  • Inspect the gasket for signs of wear or damage; replace it if necessary.
  • Lightly lubricate the gasket with silicone grease to enhance sealing.
  • Align the case back precisely before pressing or screwing it back.

For snap-on backs, press evenly around the edges using a watch press or firm fingers until the back clicks into place. For screw-down backs, use the case wrench to tighten securely but avoid over-tightening, which can strip threads or damage the case.

Maintaining proper sealing helps preserve the longevity and functionality of the Citizen watch.

I’m Arron and I’ve always liked pulling things apart just to understand how they work. Watches were a natural obsession. Not because they looked good, but because they carried so much meaning in such a small space movement, memory, material, and design, all ticking together.

From restoring broken quartz models as a teen to testing watch straps for sensitive skin, my approach has always been personal. Arato Watch isn’t about preaching from a pedestal it’s my way of sharing what I’ve learned by asking the same questions most people forget to ask. I believe watches should be understood, not just worn. That’s exactly what this site is here to help you do.
