Question about Watches
A 1100 wrench is a professional tool that shrinks the crystal applying balanced pressure to removed it without damaging it. Technically the part is a precision crystal compressor tool consisting in a metal wrench and adaptable rings. Here how it looks like (the one below is a 1200 - only the diameter is different - shape is the same) :
Once crystal is out the movement comes out through the front of the case, the back does not open and it is all in one piece
Don't try to open the watch by yourself. you will damage the case. The watch is still worth over $500. If you are located in USA I suggest contacting the professional repair below. If you are located elsewhere find a local Longines repairer or a vintage watch repairer.

Please, don't try to open the watch cause it will damage the case.
Have it repaired or restored by a certified watchmaker. Special tools will be needed exclusively for watchmakers.
The way to get through it is on the glass.

The back you are trying to remove is a screw on back, there is a special tool that you can purchase on ebay called a case opener, it fits into the slots and is rotated anti-clockwise. But be aware there are different sizes, you can hunt for the right one for your particular watch or buy a universal that will fit most types.

You will need to get a special type of spanner tool to remove the back cover. I would check with a jewerly store or a store like radio shack often has these tools so they can sell batteries. Thank you.
