Charging Time:

Please refer to the chart below to see how long it will take to charge your watch. If the watch still does not function after a long duration of charging time, the capacitor (secondary battery (aka rechargeable battery) may need replaced.

Capacitor Number:

The cal. G670 is powered by a special capacitor.

The official part number from citizen is 269-6700. You can order a replacement capacitor here (your purchase supports this site).

The capacitor type is MT416, but this doesn’t mean all MT416 cells will fit. There is a gold tone tab welded onto the battery which makes it fit in the G670 movement. See the example pictured below:

Do not attempt to fit a standard watch battery in the movement. Below is an image of the caseback of a watch with a G670M movement inside. The sticker reads:

“Use original type rechargeable battery only”
