How to Replace a Watch Battery on Your Quartz Baltimore Watch

Quick Answer

To replace the battery in your quartz Baltimore watch, you'll need a case back opener, a new battery of the correct size, and a pair of tweezers. Open the case back, remove the old battery, insert the new one, and close the case back carefully. If you're unsure about the battery size or lack the right tools, take it to a professional watchmaker.

Quartz watches are beloved for their accuracy and low maintenance, but every few years the battery runs out. When your Baltimore watch stops ticking, you might be tempted to visit a jeweler, but with the right guidance, you can replace the battery yourself at home. This guide walks you through the process step by step, including the tools you need, how to determine the correct battery size, and common mistakes to avoid.

Before you start, it's important to know that many Baltimore watches, like the Legacy Collection, are designed to be heirloom pieces. If you're not comfortable working on your watch or if it's a limited edition, consider professional service. But for standard quartz models, a DIY battery change is straightforward and can save you time and money.

Tools You'll Need

To replace a watch battery, you'll need a few specialized tools. A case back opener is essential—this can be a screw-type opener for snap-off backs or a wrench for screw-down backs. You'll also need a pair of non-magnetic tweezers to handle the battery and avoid shorting it. A soft cloth or watch mat will protect the case from scratches.

Additionally, you'll need a new battery. The correct battery size depends on your watch model. Many Baltimore watches use common sizes like SR626SW or CR2016, but it's crucial to check the old battery or the watch manual. If you're unsure, a watchmaker can help you identify the right battery.

• Case back opener (snap-back or screw-back type)
• Non-magnetic tweezers
• Soft cloth or watch mat
• New battery of the correct size

Step-by-Step Battery Replacement

Start by placing your watch on a soft surface. If your watch has a metal bracelet, you may want to use a spring bar tool to remove it for easier access. Then, determine the type of case back: snap-off or screw-down. For snap-off backs, use a case knife or a specialized opener to pry it off gently. For screw-down backs, use a case back wrench to turn it counterclockwise.

Once the case back is removed, you'll see the movement and the battery. Use tweezers to carefully lift the battery out, noting its orientation. Insert the new battery in the same position, ensuring it's seated correctly. Then, replace the case back, making sure it's aligned and pressed or screwed back securely.

• Check the gasket for wear and replace if necessary to maintain water resistance.
• Do not touch the battery with your fingers; oils can affect the contact.

Common Mistakes and How to Avoid Them

One common mistake is using the wrong battery size. Always verify the battery number before purchasing a replacement. Another is forcing the case back open, which can damage the case or movement. Use the correct tool and apply steady, even pressure.

Another frequent error is not checking the gasket. The gasket seals the watch against moisture and dust. If it's cracked or worn, your watch may no longer be water-resistant. Replace the gasket if needed, and consider applying a thin layer of silicone grease to keep it pliable.

• Always test the watch after battery replacement to ensure it's running.
• If the watch doesn't start, the battery might be dead or the movement may need attention.

Step-by-Step Battery Replacement Checklist

1. Prepare your workspace: Lay down a soft cloth and gather your tools: case back opener, tweezers, and the correct battery. Ensure good lighting. Checkpoint: Confirm you have the right battery size before proceeding.
2. Open the case back: Identify the case back type. Use a case knife for snap-off backs or a wrench for screw-down backs. Apply steady pressure to avoid slipping. Mistake to avoid: Do not pry too hard; you might scratch the case.
3. Remove the old battery: Using non-magnetic tweezers, gently lift the battery out. Note the orientation and the battery number. Checkpoint: Note the battery number for future replacement.
4. Insert the new battery: Place the new battery in the same orientation. Ensure it's seated properly and the contacts are clean. Mistake to avoid: Do not touch the battery with bare fingers; use tweezers.
5. Close the case back: Align the case back and press or screw it back on. Make sure it's secure and the gasket is in place. Checkpoint: Test the watch to ensure it's running before wearing.
