How To Open Seiko Monster Watch

Do you want to know how to open a Seiko Monster watch? Both the orange and black models of the Seiko Monster have a screwed down case back. A screwed down case back means the case back has threads on its outer edge which mate into threads in the case. They also have a case back gasket which will be discussed also. This article will discuss how to open the Seiko Monster's screwed down case back.

Tools needed to open a Seiko Monster watch:

• Adjustable case back wrench
• Case Holder
• Soft Cloth

The process of opening a Seiko Monster watch:

1. Place the watch in a case holder.  Lay the watch in the case holder if you have one. If you do not, lay it carefully upon a soft cloth to protect the crystal and bezel.
2. Make sure you have room to work before starting. In some cases, especially if the watch has a metal bracelet or deployant band, there will not be enough room to work the case wrench in a complete circle.
3. Remove the watchband/bracelet if needed. If there is no room to work properly, follow the watches instructions and remove the band or bracelet.
4. Fit the adjustable case opener to case back.. Fit the appropriate lugs on the case tool into the slots in the case back. It will take some adjusting to get it in place correctly. Patience here will insure a proper fit, which is important. Tighten it down until it does not slip free. Take care not to slip and scratch the case back or watch. This is where proper fit of the replaceable lugs comes in. Make sure that you pick the lugs which fit into the slots the best.
5. Open the watch.  Unscrew the case back in a counter clockwise motion until it comes off. Go slow and be careful, you do not want to wreck the gasket and have to replace it .
6. Check the gasket.  Inspect the case back gasket carefully. If it is damaged, it must be replaced to retain water resistance.

That is how you open a Seiko Monster watch. The process is not hard, but must be performed carefully. If you do not lay the watch on something soft or use a case holder the crystal can be scratched. If you do not fit the adjustable case wrench carefully you can slip and scratch the case back. Careful use of proper tools, and a bit of slow careful patience will pay off in a successful removal of the case back. Good luck.
