AvatarByArmando Lewellen Usage Guides

If you own a Nixon watch, you know it’s more than just a timepiece—it’s a statement of style and precision. Like any battery-powered watch, however, it will eventually need a fresh battery to keep ticking accurately. Knowing how to change a battery in a Nixon watch not only saves you time and money but also ensures your watch continues to perform at its best without unnecessary trips to the repair shop.

Replacing the battery in a Nixon watch might seem daunting at first, especially given the variety of models and designs the brand offers. Yet, with the right approach and tools, it’s a manageable task that many watch owners can confidently undertake at home. Understanding the basics of your watch’s construction and battery type is key to a smooth replacement process.

In the following sections, you’ll discover essential tips and general guidelines that will prepare you for a successful battery change. Whether you’re a seasoned DIY enthusiast or a first-timer, this guide will equip you with the knowledge to keep your Nixon watch running flawlessly.

Removing the Watch Back Cover

To access the battery of your Nixon watch, the first step is to carefully remove the back cover. Nixon watches typically have either a snap-off back or a screw-down back, so identifying the type of case back is crucial before proceeding.

For snap-off backs, look for a small indentation or lip on the edge of the back cover. This is where you will insert a case knife or a flat blade tool to gently pry the cover open. Apply steady, controlled pressure to avoid damaging the case or the seal.

Screw-down backs require a specialized tool known as a case wrench or a case opener with adjustable pins that fit into the notches on the back cover. Turn the wrench counterclockwise to unscrew the cover. Be cautious to avoid slipping and scratching the watch.

When handling the watch back, ensure you are working on a clean, soft surface such as a microfiber cloth to prevent scratching the watch face or case. Additionally, avoid touching the internal components with your fingers to minimize the risk of contamination or damage.

Identifying and Removing the Old Battery

Once the back cover is removed, you will see the watch’s movement and the battery compartment. The battery is usually held in place by a small clip or a metal arm that may be secured with a screw.

Before touching any components, note the battery type and orientation. Most Nixon watches use button cell batteries, and common types include SR626SW, CR2032, or others, depending on the model.

To remove the old battery:

  • Use plastic tweezers or a non-metallic tool to avoid short-circuiting.
  • Carefully lift or unscrew any retaining clips.
  • Gently extract the battery, noting its position and polarity (usually the positive side faces up).

Keep the old battery aside for proper disposal according to local hazardous waste regulations.

Installing the New Battery

After removing the old battery, prepare the new one for installation by confirming it matches the model and voltage specifications. Insert the new battery in the same orientation as the old one, ensuring proper contact with the terminals.

Secure the battery by replacing any clips or screws that held the original battery in place. Avoid applying excessive force which could damage the battery or movement components.

Before sealing the back cover, check that the watch is functioning correctly by observing the second hand or digital display. If the watch does not start, recheck battery placement and contacts.

Resealing and Closing the Watch Back

Properly resealing the watch back is essential to maintain water resistance and protect internal components from dust and moisture.

For snap-off backs:

  • Align the cover with the case, ensuring the gasket or rubber seal is properly positioned.
  • Press down firmly and evenly until the cover snaps back into place. Use a watch press tool if available for even pressure.

For screw-down backs:

  • Confirm the gasket is intact and lightly lubricate it with silicone grease if necessary.
  • Screw the back cover clockwise using the case wrench until snug, but avoid over-tightening which can damage threads.

Check the watch for any gaps or misalignment after closing. If the watch is rated for water resistance, consider having it pressure tested by a professional to verify the seal integrity.

Battery Types Commonly Used in Nixon Watches

Nixon watches employ a variety of button cell batteries depending on the model and functions (e.g., analog vs. digital). The following table lists common battery types along with their nominal voltage and typical applications.

Battery Model Nominal Voltage (V) Common Nixon Watch Models Battery Chemistry
SR626SW 1.55 Analog quartz watches Silver oxide
CR2032 3.0 Digital and multifunction watches Lithium
SR920SW 1.55 Chronograph models Silver oxide
SR621SW 1.55 Thin analog watches Silver oxide

Opening the Nixon Watch Case

Changing the battery in a Nixon watch begins with carefully opening the case back. Nixon watches typically feature either a snap-off or screw-down case back, depending on the model.

  • Gather appropriate tools: Use a case knife or a small flat-head screwdriver for snap-off backs; for screw-down backs, a case wrench or a precision screwdriver set is required.
  • Prepare a clean workspace: Use a soft cloth to protect the watch face and prevent scratches.
  • Identify the case back type: Look for a small notch or indentation around the case back edge for snap-off types or multiple slots/holes for screw-down types.
  • Opening the case:
    • Snap-off back: Insert the case knife carefully into the notch and gently twist or pry upwards until the back pops off.
    • Screw-down back: Align the case wrench with the slots or holes and turn counterclockwise to unscrew the back.

Important: Apply minimal force to avoid damaging the watch or its seals. If resistance is excessive, it may be safer to consult a professional technician.

Removing and Identifying the Battery

Once the case back is removed, the battery compartment becomes accessible. Proper handling is crucial to avoid damaging internal components.

  • Inspect the battery housing: Note whether the battery is held by a clip, screw, or plastic cover.
  • Remove retaining mechanisms: Use tweezers or a precision screwdriver to carefully release any clips or screws securing the battery.
  • Extract the battery: Gently lift the battery using plastic tweezers or a non-metallic tool to avoid short circuits or corrosion.
  • Identify the battery type: Look for the battery model number engraved on the battery surface, typically a three- or four-digit code such as SR626SW or CR2032.
Battery Code Common Watch Use Voltage
SR626SW Quartz wristwatches 1.55 V
CR2032 Digital watches, some Nixon models 3 V
SR927SW Analog watches 1.55 V

Note: Always replace the battery with an identical type to ensure proper function and water resistance.

Installing the New Battery and Reassembling the Watch

Installing the replacement battery correctly ensures the Nixon watch operates reliably and maintains its integrity.

  • Insert the new battery: Place the battery in the compartment with the correct polarity—usually the positive side facing up. Refer to the watch or battery holder markings if uncertain.
  • Secure the battery: Reattach any clips, screws, or covers that held the original battery in place.
  • Check watch function: Before closing the case, verify that the watch hands are moving or the digital display is active.
  • Replace the case back:
    • Snap-off back: Align the back cover with the case and press firmly until it snaps into place, ensuring the gasket remains correctly seated to preserve water resistance.
    • Screw-down back: Place the back cover and use the case wrench to tighten clockwise, applying even pressure to avoid cross-threading.
  • Perform a water resistance test: If possible, have the watch tested professionally to confirm that seals and gaskets remain intact after battery replacement.

Tip: Avoid touching the new battery surface with bare fingers to prevent corrosion from oils and dirt. Use gloves or plastic tweezers when handling.
