2.1 Unpacking
Carefully remove the clock from its packaging. Inspect the clock for any signs of damage. Retain all packaging materials for future transport or service needs.

- Remove the cover by sliding or gently prying it open.

2.3 Setting the Time
To set the correct time:
- Gently turn the minute hand (the longer hand) clockwise only until the desired time is displayed. Avoid turning the hands counter-clockwise to prevent damage to the movement.
- Allow the clock to chime at each hour or quarter-hour as you advance the hands. This synchronizes the chime with the time.
2.4 Placement
Place your Bulova B1975 clock on a stable, flat surface such as a mantelpiece, shelf, or desk. Ensure it is away from direct sunlight, extreme temperatures, and high humidity to maintain its finish and accuracy.

3. Operating Instructions
3.1 Chime Selection
Your clock features a Harmonic 2 triple-chime movement, offering three distinct melodies:
- Westminster: A classic, familiar chime.
- Ave Maria: A melodic, serene tune.
- Bim-Bam: A simple, two-note chime.
A switch located on the back of the clock, typically within the battery compartment area, allows you to select your preferred chime melody. Refer to the markings near the switch for specific settings.
3.2 Quarter-Hour Westminster Chime and Strike
When the Westminster chime is selected, you have the option for a quarter-hour chime and strike. This feature plays a portion of the Westminster melody at each quarter-hour mark, followed by the full melody and hour count on the hour:
- Quarter Past: Plays 1/4 of the Westminster tune.
- Half Past: Plays 1/2 of the Westminster tune.
- Quarter To: Plays 3/4 of the Westminster tune.
- On the Hour: Plays the full Westminster tune, followed by the corresponding number of strikes for the hour.

3.3 Adjustable Volume Control
The clock features an adjustable volume control for the chimes. This control is typically a rotary knob located near the chime selection switch on the back of the clock. Turn the knob to increase or decrease the chime volume to your preference.
3.4 Automatic Night Shutoff
For undisturbed sleep, the clock includes an automatic night shutoff feature. When activated, the chimes will automatically silence between 11:00 PM and 5:45 AM. Consult the markings near the chime controls for the specific switch setting to enable or disable this feature.
4. Maintenance
4.1 Cleaning
- Dust the clock regularly with a soft, dry cloth.
- For the wood finish, use a furniture polish specifically designed for wood, applied sparingly to a soft cloth, then gently wipe the surface. Avoid abrasive cleaners or harsh chemicals.
- Clean the convex glass lens with a soft, lint-free cloth. If necessary, dampen the cloth slightly with a mild glass cleaner, then wipe dry immediately.
4.2 Battery Replacement
Replace all batteries annually, or sooner if the clock's timekeeping becomes erratic or the chimes weaken. Always replace all batteries at the same time with new, high-quality alkaline batteries. Do not mix old and new batteries, or different types of batteries.
4.3 Movement Care
The clock's quartz movement is designed for long-lasting, accurate performance and does not require lubrication. Do not attempt to disassemble or repair the movement yourself, as this will void the warranty. Refer to qualified service personnel for any repairs beyond battery replacement.
5. Troubleshooting
If you experience issues with your Bulova B1975 clock, please refer to the following common problems and solutions:
