Hey! A pocket watch shard that sighs—classic. Let’s find its heart. First, clean the brass; grime hides gears. Then, spot the tiny pivot—if it’s corroded, gently polish with a fine steel wool or a brass cleaner. Next, re‑attach the balance wheel; that’s the heart that beats the rhythm. Use a small toothpick or a needle to slot it back, making sure it’s centered. Finally, give it a gentle tap on the case—if the sound steadies, you’ve found the pulse. If it still sighs, try a tiny bit of oil on the pivots; the right amount will smooth the motion. Need any specific tools? Let me know and we’ll tweak the design together.
