Restrained grief

The prompt

Close-up of an elderly Japanese watchmaker with a fine grey moustache at his cluttered workbench beside an open wooden music box, warm tungsten light, fixed framing. 0–2s: he listens with a quiet, neutral expression, a magnifier loupe pushed up on his forehead. 2–6s: his inner eyebrows lift, his eyes grow wet, and his lower lip begins to tremble. 6–8s: he presses his lips together and attempts a fragile smile as a tear gathers on his lashes. Throughout: tiny brass gears and clock faces softly out of focus behind him, the music box's comb turning slowly, warm amber light, stationary camera.
