Fine brass accents on time pieces should only be handled with a soft cotton cloth. If you have to touch the weights, pendulum, etc, wipe the touched area to remove all finger prints, smudges and transferred oils. NEVER use abrasive cleaners as permanent damage will result. Polishes should not be used with an any remaining trace might work its way into the movement causing great harm . Entrust this work only to professionals who clean, polish, and then lacquer the parts for years of good looks. We see many items ruined when excess polish worked its way into the delicate mechanism where it acts like a grounding compound quickly causing wear.

Cleaning Glass

Avoid getting glass cleaning products on the brass, painted, or wood surfaces. Spray the cleaner onto the cleaning cloth (soft, clean, cotton cloths work best–an old T-shirt, etc.) and then wipe the glass surfaces on both sides. Never spray the cleaner directly on the clock as the resulting "cloud of chemicals" may invade the protective environment of the mechanism. Never try to clean any glass surface which is reverse-painted, stenciled, or decorated with a decal as these delicate finishes may be permanently damaged. Also make sure you know your "glass" some models of the Lecoultre Atmos clock use both plexiglass and glass on the same unit. My customer tried to use a thinner to remove a sticker residue which etched and clouded what turned out to be plastic.

NEVER...

1. Help the weight while winding by lifting it, only raise the weight with the crank, or a smooth and even downward pull on the chain.

2. Move a clock with a pendulum attached.

3. Polish the brass parts of a clock

4. Set a clock backward unless you know for sure that your clock has a back-wards release setting clutch.

5. Set the hands of a clock while it is striking as this may cause a jammed condition.

6. Swing the pendulum with excess force, or stress the suspension spring due to heavy-handedness.

7. Try to clean the dial of a clock.

8. Wind a clock with a ill-fitting or damaged key.

9. Wind a clock with a sizing key.

ALWAYS...

1. Set a timepiece in the clockwise direction.

2. Wind a clock to completion.

3. Instead of winding a clock backwards, stop it and restart it at the correct future time.
