Seiko 3027 26Z (No Returns)

Genuine Seiko 3027 26Z capacitor, complete with the correct clip, designed for select Seiko solar-powered watch movements. This rechargeable cell is essential for restoring proper charging and power retention in your Seiko timepiece.

✅ Correct Fitment – Calibre Number is Key

To ensure compatibility, always check the calibre number engraved on the movement of your watch (not the number on the cell itself).
While many capacitors may share the same cell number, the clip style and soldering configuration differ, and using the wrong type may cause damage or malfunction.

⚡ Important Charging Information

New capacitors ship with little or no charge and must be recharged after installation:

• Solar watches: Place the watch in direct sunlight, preferably a sunny windowsill.

• Kinetic watches: Charge by wearing the watch regularly or using a suitable charger.

Charging may take several hours. If your watch still does not retain power, the issue may lie with the charging circuit or internal movement, not the capacitor.

⚠️ No Returns Policy: Capacitors are electronic components and cannot be returned once opened or fitted.
