Howard Miller Theodore Grandfather Clock 615164

Partially verified

The Howard Miller Theodore Grandfather Clock (model 615164) is a floor-standing timekeeping instrument featuring a black iron frame. The design includes a head assembly finished in aged silver, containing a convex glass dial with motorized, pierced Roman numerals and hour markers. The clock incorporates an exposed gear system finished in aged silver that can rotate in both clockwise and counterclockwise directions via an integrated hand wheel. The structure includes wood accent panels and a base shelf finished in graphite gray. Illumination is provided by an LED system within the dial, adjustable via a touch dimmer pad with four settings. The clock is powered by a time-only quartz movement requiring one AA battery and three D batteries. Stability is supported by four adjustable floor flanges. Overall dimensions measure 77.75 inches in height, 18.75 inches in width, and 14 inches in depth.

Object description

Structural Design and Materials

The Howard Miller Theodore clock is constructed primarily from a black iron frame, which serves as the skeletal structure for the floor-standing timepiece. The design integrates wood accent panels and a base shelf, both finished in a graphite gray tone, providing contrast to the metal framework. For stability, the base is fitted with four adjustable floor flanges, intended for positioning on various surface types, including carpet or uneven flooring.

The visual profile is defined by an open-gear mechanism mounted centrally within the iron frame. This gear assembly is finished in aged silver, matching the head assembly that houses the clock dial. The lower section features a wood-surfaced shelf, intended for the display of personal items, effectively combining the clock's verticality with functional storage space.

  • “this black iron grandfather clock features captivating moving gears”
  • “wood accent panels in a graphite gray finish”
  • “four adjustable floor flanges provide steadfast support”
  • “The base boasts a wood shelf finished in graphite gray”

Dial and Lighting

The clock head contains a convex glass dial that serves as the visual center of the piece. The dial features Roman numerals and hour markers that are pierced and motorized, moving behind the glass surface. The hour and minute hands, along with the gear components visible within the dial, are finished in aged silver to maintain aesthetic consistency with the rest of the clock's framework.

Internal LED lighting is incorporated into the dial assembly, which is diffused through a translucent lens to produce a soft, ambient glow. A touch-sensitive dimmer pad is provided for control, offering users four distinct illumination levels: low, medium, high, and an off position. This system is designed to improve visibility while acting as an ambient light source for the room.

Evidence for this section
  • “Adorning the dial are pierced, motorized moving Roman numerals and hour markers”
  • “convex glass dial, backlit with LED lighting diffused through a translucent lens”
  • “touch dimmer pad, offering four levels of illumination: low, medium, high, and off.”

Movement and Operation

The clock is driven by a time-only quartz movement, which is battery-operated. Power is provided by a combination of one AA-sized battery and three D-sized batteries, which are not included with the unit. This electrical system powers both the timekeeping function and the motorized elements of the clock, including the dial markers and the rotating gear assembly.

The secondary gear system, positioned below the dial, can be manipulated by the user. A hand wheel allows for the clockwise or counterclockwise rotation of these gears, creating a kinetic display that is independent of the timekeeping movement. This feature is intended to enhance the visual experience of the clock, echoing the appearance of traditional verge mechanisms while functioning through modern motorized components.

Evidence for this section
  • “Powered by a time-only, quartz battery-operated movement”
  • “the gears rotate clockwise and counterclockwise with the turn of the hand wheel”
  • “The unique pendulum bob, reminiscent of the verge on a mechanical clock movement”

Open research questions

  • What is the specific material composition of the 'black iron' frame?
  • What is the anticipated operational lifespan of the motorized gear system under continuous use?
