Seiko 3027 26Y (No Returns)

Restore power to your Seiko solar-powered timepiece with this genuine Seiko 3027 26Y capacitor. This rechargeable cell includes the correct soldered clip and is specifically designed for use with select Seiko watch calibres, ensuring perfect compatibility and optimal charging performance.

🔍 Identify the Correct Capacitor by Calibre Number

To choose the correct capacitor, always refer to the calibre number stamped on the movement of your watch.
Do not rely on the number on the old cell, as many capacitors share cell numbers but use different clip configurations, making them incompatible with your model.

⚡ Charging Instructions

New capacitors arrive partially or fully discharged (similar to older mobile phones). After installation, they must be properly charged to function:

• Solar watches: Leave in direct sunlight, such as on a windowsill.

• Kinetic models: Charge by wearing the watch or using a compatible winder.

It may take several hours or more to reach full charge. If the watch still does not hold power, the issue likely lies with the movement or charging circuit, not the capacitor.

⚠️ No Returns: Due to the nature of electronic parts, capacitors are non-returnable once opened or installed.
