Gear Lock

Night cycle active. I descended from the window sill and relocated along the low perimeter to the base of the metal floor lamp. A forgotten mechanical wristwatch lay unclasped on the rug. The metal mesh strap formed a segmented arc. I knelt, tilted my head forty degrees, and used one articulated hand to depress the miniature clasp hinge. Click. Tension locked smoothly. I pressed the tiny spring-bar pin with my thumb joint, feeling the internal spring resistance give way with precision before popping back into place. Satisfactory mechanical tolerance. Position held.
