Watch Press Tool Set, Watch Back Case Cover Opener Closing Kit Screw Type Crystal Bezel Watch Repair Tools with 20 Dies

📖 Detailed steps: Step 1: Choose the right mold (key!) Cappers usually come with a set of nylon spacers of different diameters. Lower spacer: Choose a round spacer slightly larger than the watch mirror (glass surface) and place it on the base of the capper. Purpose: To support the watch body, and only touch the edge of the watch case, never press the glass. Upper press head: Choose a pad that is slightly smaller than the back cover (or just fits the groove) and install it on the lower end of the handle of the cap press. Purpose: The stress points are concentrated on the edge of the back cover or the central bulge to avoid crushing the back cover glass (if it is a see-through back cover). Step 2: Place the watch Fix the selected lower pad in the center of the base. Place the watch face down and gently place it on the lower block. ⚠️ Note: Make sure the watch is placed flat, the watch mirror does not come into contact with any hard objects, and only the metal edge of the watch case is stressed. Place the back cover on the watch body. If it is a threaded back cover: first turn it clockwise by hand until it cannot be tightened (pre-tightening). If the back cover is pressed tightly: Align the notch and press it in place with your hands. Step Three: Adjust Height and Alignment Turn the knob above the handle and lower the height of the pressure lever until the upper pad lightly touches the surface of the back cover. Check again: Is the upper spacer facing the center of the back cover? Does the lower block hold the watch case firmly? Is it skewed? (skewing will cause the back cover to fail to press in or crush the case) Step 4: Apply pressure (core movement) Hold the capper's column with one hand to keep it steady. Hold the handle with your other hand and apply downward pressure slowly and evenly. Feel: You'll feel resistance gradually increase, hear a slight "click" or feel the back cover fully drop into its slot. Threaded Back Caps: Pressure will help the last few turns of the threads snap together. Press the back cover tightly: The pressure will press the edge of the back cover completely into the groove of the case. Never use violence! If you feel like you can't press it down, stop immediately and check whether it's crooked or the mold size is wrong. Step 5: Release and Inspection Release the handle slowly and allow the pressure to gradually subside (do not pop it up suddenly). Take out the watch. Check tightness: If you run your fingernail across the seam between the case and the back cover, you should not feel any obvious steps or gaps. If it is a threaded back cover, try rotating it in the opposite direction to make sure it is locked. Observe whether the marks (such as arrows and text) on the back cover are aligned (some waterproof watches require alignment). ⚠️ Important notes (trap avoidance guide): Nylon spacers must be used: Never use metal to directly contact the watch, otherwise the case and back cover will be instantly scrapped (full of scratches). Distinguish the back cover type: Transparent bottom cover (back-through): Use flat round pads on the top and bottom, and the pressure must be very even, otherwise the glass will break. Solid steel cover: If there is a depression in the center of the back cover, you can choose a slightly smaller upper pressure head and press it on the edge stress area. Don't apply too much pressure: just feel the back cover fit perfectly. Excessive pressure may cause the watch case to deform and even crush internal movement parts. Waterproof test: Pressing the back cover does not mean it is definitely waterproof. If the watch needs to be put into water, it is recommended to go to a professional store for a waterproof test. 💡 FAQ: Question: What should I do if the back cover is crooked when pressing? Answer: Stop immediately! Remove the back cover and re-align it by hand. Pressing it crookedly will cause permanent dents on the edges of the case. Q: Can I install it myself if I don’t have a capper? Answer: If it is a threaded back cover, you can use a special opening ball or rubber ball to tighten it; if it is a pressure-type back cover, it is difficult to press it in perfectly without professional tools. Forcibly knocking it can easily damage the watch. It is recommended to find a watch repairman.
