Isn't funny that once you have a watch that requires a battery change, you find that you have another that requires battery change as well? Well, I found a number of my watches requiring battery change. This time we will look at the Timex K9 watch battery change.
The watch with the case back removed. The case back is held by four screws. The gasket is fitted to the case back.
Since the case back has been removed, you can see how the chronograph pushers connect with the movement.
Another view of the pushers.
The battery is held in place by a metal plate. Unlike Casio watches, the metal plate is held in place by a screw and a locking tab (the mechanism at the 5:30 o'clock position).
The metal plate removed. I believe the movement is made by Timex Philippines. Stamped on the metal plate is 'TMX Philippines'. You can see the screw that holds the plate in position at the top of the plate.
The battery, ready to be removed. It is further held in place by the tab at the 6 o'clock position. This tab is part of the locking mechanism we saw earlier.
A clear view of the movement. There is no indication of where it is made and by whom. The movement number: M921.08. It is a pretty big movement.

The case back. The battery information is on the case back. This makes it easier to buy the battery without having to remove the case back. You can see the four screws that holds the case back in place.
The inside of the case back. It is made in China. The gasket fits on the case back. It has been removed to be lubricated.
The new battery. In this case, it is the CR2016.
The new battery fitted. Check that the watch works before you refit the case back. Also check the EL backlight.
The metal plate fitted.
The watch all done and ready.
