Watch 3 Prongs Case Opener / Spanner with 4 Sets of Pins

Ever struggled to get the back off your watch to replace the battery? Well here is the solution for screw back cases but before you buy make sure you select the correct spanner! When you look at the back of your watch, if it has a screw back case there will be either flat rectangular slots around the edge of the watch back or round ones. If the slots are round then this is the spanner for you. If the slots are flat then please search ASIN B00K2ST4BG in the Amazon search box for the correct tool. This simple but effective tool has two blades that can be adjusted with the adjustment wheel in the middle of the tool handle, the blades will move from a diameter of 15mm up to 50mm. The blades fit into the round cut outs on the back of the watch and you simply twist anti-clockwise to remove the back and clockwise to tighten it up, which makes it possible for you to simply (and cheaply) replace batteries in your own watches. Some points of caution when using this tool

1) place a soft cloth or other protective material between your watch and the work surface to prevent scratching you watch crystal- we recommend the lint free microfiber cleaning cloth by SWISS REIMAGINED (AIN:B00OR2IZOK)
2) we recommend placing a thin piece of fabric between the spanner and your watch case to prevent any scratching during the process of removing or replacing the back
3) when you screw the watch back on again be very careful not to cross the threads of the watch back and the watch case, in the first stages it should spin easily in the threads and finally
4) if your watch is waterproof rated and you take the back off you should assume that it is no longer waterproof afterwards unless you have it tested - something a good watch repair shop will be able to do for you
