18ct gold open face, quarter 'dumb' repeater pocket watch, White enamel dial with Roman numerals, rail track minutes, winding hole at II. Fusee verge movement. Plunger actuated dumb repeater mechanism. Glass loose. Total weight 110gm Used by the visually impaired and to tell the time quietly in meetings and concerts, 'dumb' repeater watches did not chime audibly, but instead produced vibrations. Instead of a gong, the hammer struck the hours on a solid metal block attached to the case, producing a dull 'thud' that could be felt in the hand.
