Seiko 3023 5MY = 3023 5MZ (No Returns)

Restore your Seiko Kinetic watch’s power and reliability with a genuine Seiko 3023 5MY capacitor, complete with the correct factory-soldered clip. This rechargeable cell is specially designed for use with a range of Kinetic calibre movements, providing dependable energy storage and long-term performance.

🔍 Compatibility Note – Check the Calibre:

To ensure proper fit and function, always confirm the calibre number stamped on your watch movement.
Do not rely on the number printed on the capacitor itself, as identical cell types may be paired with different clips. These clips vary by model and make the capacitors non-interchangeable across calibres.

⚡ Charging Instructions:

New capacitors are shipped with very low or no charge, similar to older mobile phone batteries. After installation, they must be charged:

• For solar models: Place the watch in direct sunlight (ideally on a windowsill).

• For Kinetic models: Wear the watch to activate the internal rotor-based charging system.

Full charging can take time. If the watch does not hold a charge after proper installation and charging, the issue may lie with the charging mechanism or movement, not the capacitor.

🚫 Please Note: Capacitors are electrical components and cannot be returned once opened or installed.
