This is a Bergeon 4657 professional dust blower with a PVC nozzle, designed for dust‑free environments in watchmaking, precision electronics, jewelry processing, and similar fields. By manually pressing the bulb, it generates a strong yet controllable stream of air to safely and efficiently remove dust and micro‑particles from movement parts, dials, crystals, circuit boards, and other delicate surfaces.
It eliminates the risks of contamination or condensation associated with canned air or mouth blowing. This product is genuine Bergeon, made in Switzerland, and brand new in original packing.

| Fine Tip | Reaches tight spaces such as movement gaps and jewel settings. |
| Check Valve | Prevents dust from being sucked back into the bulb, ensuring clean air output. |
| Durable & Wear‑Free | Rubber bulb is long‑lasting with no consumable parts. |
| Safe & Eco‑Friendly | No chemical propellants, no condensation risk, environmentally safe. |
Preparation：Place the dust blower on a clean, dry workbench.
Aim：Direct the PVC nozzle tip toward the part to be cleaned, maintaining a distance of about 1‑2 cm.
Press：Quickly and firmly squeeze the rubber bulb to release a strong burst of air. Repeat until dust is removed.
Refill：Release the bulb; the internal check valve automatically opens to draw in fresh air.
Repeat：Squeeze as many times as needed.
Storage：Store the dust blower in a dry, dust‑free place, away from crushing or deformation.
Tip：For stubborn dust, tilt the nozzle at an angle and blow from the side. Avoid touching the nozzle directly against delicate parts (e.g., hairspring, pallet fork) to prevent accidental damage.
This product requires no “installation”; it is ready to use out of the box. Before first use:
Inspect the nozzle for secure fit and the rubber bulb for any tears.
Squeeze the bulb several times away from your workpiece to clear any dust that may have entered during packing or transport.
Test the airflow to become familiar with the pressure.
Cleaning：If the nozzle exterior becomes soiled, wipe with a soft cloth lightly dampened with mild soapy water, then dry.
Inspection：Periodically check the bulb for cracks and the nozzle for looseness or deformation.
Replacement：The Bergeon 4657 is a single‑piece unit. If the bulb ruptures or the check valve fails, replace the entire unit.
Shelf Life：Rubber naturally ages over time; store in a cool, dry place to maximize service life.
Q1: Can I use the Bergeon 4657 to clean watch movements?
A: Yes. It is a standard tool in watchmaking for cleaning movement parts, dials, and crystals. Maintain a safe distance and avoid direct contact with the gear train or hairspring.
Q2: Does the dust blower blow out oily mist or moisture?
A: No. The Bergeon 4657 is a purely manual air blower; it does not generate any oil mist or condensation. When used in a dry environment, the output is dry, clean ambient air.
Q3: Can the nozzle be removed for cleaning?
A: The nozzle is friction‑fitted and can be gently pulled out for cleaning. However, frequent removal may loosen the fit. It is recommended to remove only when necessary and to clean the exterior with a soft cloth.
Q4: What is the advantage of this blower over canned air?
No consumables: no need to buy canned air; very low operating cost.
No condensation: canned air can spray liquid propellant, damaging delicate parts.
Eco‑friendly: no propellant emissions.
Controllable: manual pressure allows variable airflow intensity for different tasks.
