Howard Miller Riella Grandfather Clock 615146

Partially verified

The Howard Miller Riella, model 615146, is a floor clock featuring a tall, slender construction designed with an industrial, gear-themed aesthetic. The clock is composed of select hardwoods and veneers finished in a Seaside Gray color, accented by charcoal gray metal plates on the vertical column and base. The base is equipped with leveling feet for stability on floor surfaces. The dial is designed as a large wooden gear, while a fixed internal metal gear with a charcoal gray finish indicates the 12, 3, 6, and 9 o'clock positions. The center of the dial features motor-driven galvanized gears that rotate continuously. It is powered by a quartz movement requiring one AA, one D, and two C batteries to operate the time-only display. A gear-shaped pendulum finished in charcoal gray is suspended from the lower section of the column.

Object description

Design and Construction

The Riella clock is constructed from select hardwoods and veneers with a Seaside Gray finish. The design centers on a tall, vertical column supporting a gear-shaped dial and a gear-shaped pendulum. The structure includes charcoal gray metal plates on the column and base to enhance the intended industrial look.

Stability is maintained by leveling feet attached to the base, which allows for adjustment on various floor surfaces. The overall proportions result in a height of 80 inches, a width of 20 inches, and a depth of 9.5 inches.

Evidence for this section
  • “بدنه اصلی این ساعت از چوب‌های سخت منتخب و روکش‌های چوبی با رنگ Seaside Gray (خاکستری ساحلی) ساخته شده”
  • “پایه‌های ساعت مجهز به ترازکننده‌های قابل تنظیم بر روی زمین می‌باشند.”

Dial and Mechanism

The clock dial is carved into the shape of a large gear, finished in Seaside Gray. Fixed metal gears finished in charcoal gray mark the cardinal positions of 12, 3, 6, and 9. At the center of the dial, a set of motorized gears with a galvanized finish provides continuous rotation.

The timekeeping display features black hour and minute hands, accompanied by a sweeping red second hand. The clock operates on a quartz movement and serves a time-only function. Power is supplied by a combination of one AA, one D, and two C batteries.

Evidence for this section
  • “چرخ‌دنده داخلی و ثابت فلزی با روکش خاکستری زغالی موقعیت ساعات ۱۲، ۳، ۶ و ۹ را نشان می‌دهد.”
  • “عقربه‌های ساعت‌شمار و دقیقه‌شمار مشکی‌رنگ و عقربه ثانیه‌شمار با حرکت پیوسته (sweep) به رنگ قرمز طراحی شده است.”

Condition and Maintenance

The clock is described as factory new. Given the reliance on battery power for the timekeeping and the motorized gear animation, the manufacturer notes that the battery types and the alignment of the base must be verified prior to operation.

Users are advised to inspect the health of the central motorized gear circuit to ensure smooth operation of the rotating components.

Evidence for this section
  • “وضعیت ساعت کاملاً نو و آکبند کارخانه‌ای (Factory new) ذکر شده است.”
  • “پیش از راه‌اندازی، خریداران باید نوع باتری‌های مورد نیاز، هم‌ترازی پایه‌ها و سلامت مدار چرخ‌دنده‌های متحرک مرکزی را بررسی نمایند.”

Open research questions

  • What is the specific maintenance interval for the motorized gear assembly?
  • What is the material composition of the galvanized gears?
