How to Replace a Seiko Watch Battery

Replacing the battery in a Seiko watch can be a straightforward process if you follow these steps:

1. Gather Your Tools: You'll need a case opener, a new battery, and a pair of tweezers.
2. Open the Case: Use the case opener to gently pry open the back cover. Ensure you do this carefully to avoid scratching the casing.
3. Remove the Old Battery: Carefully take out the old battery using tweezers. Note the orientation, as this will be essential when inserting the new battery.
4. Insert the New Battery: Place the new battery in the same orientation as the old one, making sure it sits snugly in its compartment.

• Avoid Extreme Conditions: Keep your watch away from extreme temperatures, magnetic fields, and harsh chemicals.
• Water Resistance Checks: If your watch is water-resistant, have it tested annually to ensure seals are intact.

Product Comparisons: OEM vs. Aftermarket Parts

• Cost: Aftermarket options are often cheaper, but they may not fit as perfectly or perform as reliably as OEM parts.
• Warranty: Using OEM parts generally keeps your warranty intact, while aftermarket parts can void warranties.
• Performance: For critical components like movements and batteries, OEM parts are usually the better choice for optimal performance.

When in doubt, opt for genuine parts to ensure the best care for your timepiece.
