Disassembling a wristwatch in order to clean it or replace a part, one may encounter the difficulty of removing the crown. The clockwork is quite fragile and requires diligence, so this must be done very carefully and carefully. Otherwise, you can damage not only the case, but also permanently break the device.
Instructions
Step 1
Prepare a workplace where you will disassemble the watch. Place a large white sheet on the table, set up a table lamp with a sufficiently bright light. Place several boxes in front of you in which you will fold all the parts of the clockwork so as not to lose. In this case, it is necessary to fold the structural elements separately, which will later make it much easier to put back the watch. You can also prepare a camera. Do not rely on memory alone; take pictures of each stage of disassembly of the mechanism.
Step 2
Detach the bracelet from the watch and set it aside with the screws. Examine the structure of the watch case. If it is fastened with snaps, then use a thick-bladed screwdriver or knife to hook the fastener and open the case. If the body has a thread, then first you need to clean it from dust and dirt accumulated during the time. This can be done with gasoline, do not use water, which can corrode the mechanism.
Step 3
Unscrew the threaded ring with powerful tweezers. Having opened the case, first carefully examine the movement and take a picture, after that you can get it out after removing the crown.
Step 4
Place the watch face down on a piece of paper. Examine the crown. Do not try to unscrew it. Examine the place where the winding shaft enters the watch case. Some models have a small dot-shaped pin near this point. It is necessary to press it with a convenient tool and at the same time pull the winding lever to the side. As a result, the head will be detached. There are also watch models in which a screw is installed instead of a pin. In this case, it is necessary to turn it half a turn and calmly get the crown out.
Step 5
Place the crown back into the watch movement as soon as you remove it from the case. You will need it later when analyzing other parts. This element is inserted in the same way as it is removed.
