Learn how to safely replace the battery in your Tsao Baltimore quartz watch. Step-by-step instructions for DIY battery change and when to use our walk-in service.

Quick Answer

You can replace the battery in your Tsao Baltimore quartz watch at home with basic tools, but if you prefer a hassle-free option, our walk-in battery service handles it in minutes.

When to DIY vs. Walk In

Changing a watch battery yourself saves time and money, but it requires care. A wrong move can scratch the caseback or damage the movement. If you lack the tools or steady hands, our walk-in battery replacement service is a safe alternative.

What You'll Need

For a DIY battery change, you need a caseback opener (knife-style or wrench), a small screwdriver, tweezers, and the correct replacement battery (often a silver-oxide cell like SR626SW). Avoid using metal tools near the movement to prevent short circuits.

Step-by-Step Battery Replacement

Open the Caseback: Use a caseback opener to twist off the back. For snap-on backs, insert a knife-edge into the notch and pry gently. Common mistake: using too much force can scratch the caseback or bend the tool. Work slowly.
Remove the Old Battery: Use tweezers or a small screwdriver to lift the battery out. Note the orientation of the positive (+) side. Checkpoint: do not touch the movement's circuit board with metal—static can damage it.
Insert the New Battery: Place the new battery in the same orientation as the old one. Press down gently until it clicks into place. Common mistake: forcing the battery can crack the cell or bend the contact spring. If it doesn't fit, check the battery type.
Close the Caseback: Align the caseback with the groove and press or screw it back on. Ensure the gasket is seated for water resistance. Checkpoint: if the gasket is dry or cracked, replace it to maintain water resistance.
