Notes

• The 30235MY is the current active Seiko part number; 30235MZ is the discontinued predecessor — they are the same capacitor.
• The cell marking (TC920S) refers to the base cell chemistry; the Seiko part number specifies the tab configuration for each calibre family.
• Seiko Kinetic watches use a rechargeable accumulator, not a standard battery — do not fit a conventional battery in its place.
• Professional installation is recommended if you are not experienced with Kinetic movement servicing.
