The HR1688 Silent Sweep Quartz Clock Movement utilizes a 32.768KHz quartz crystal for timekeeping. It operates within a 1.3-1.7V range using standard AA batteries. This version upgrades the traditional stepping pulse to a continuous sweep, eliminating all ticking sounds.
Key Features
- Noiseless Sweep Second Hand: Continuous motor rotation eliminates audible ticking sounds. It stays silent in quiet bedrooms or study areas.
- High Torque Drive: Increased motor power supports oversized or heavy clock hands. It maintains steady rotation without stalling under physical load.
- Nylon Gear Durability: Internal components use high-density synthetic polymers for friction reduction. These parts resist wear despite the constant motion of the sweep mechanism.
- Timekeeping Precision: Crystal oscillator maintains timing within ±30 seconds per month. Road dust won't easily penetrate the sealed housing to disrupt the gears.
Frequently Asked Questions
What is a silent sweep clock movement?
A sweep movement uses a continuous motor drive instead of a one-second pulse. This removes the ticking noise found in standard quartz clocks.
How to replace a wall clock machine?
Unscrew the center nut and pull the old hands off the 8mm shaft. Press the new HR1688 unit into place and reattach the hands in order.
