Bergeon 5767-F Watch Spring Bar Tool In Aluminium

Product Description

The Bergeon 5767‑F is a Swiss‑made aluminium spring bar tool designed for watchmakers to safely install and remove spring bars from metal and leather watch straps. Its black anodised aluminium body is lightweight and durable, providing a comfortable grip for precise work. The tool features two interchangeable ends — a fine point (0.80mm) and a fork (1.30mm) — both made of hardened stainless steel, suitable for tackling different types of spring bars.

Features & Function

Swiss Made: Manufactured by Bergeon, a premier Swiss toolmaker, ensuring top quality and adherence to professional watchmaking standards.

Lightweight Aluminium Body: The handle is made of black anodized aluminium, which is lighter and more corrosion‑resistant than traditional brass models (e.g., 6767‑F), reducing fatigue during extended use.

Dual‑End Design:
— Pointed End (0.80mm): Used to compress shouldered spring bars, especially those hidden inside lug holes, by pressing from the back side of the spring bar.
— Forked End (1.30mm): Used to pry open spring bars, ideal for non‑drilled lugs or when accessing the spring bar from the gap between the strap and the case.

Interchangeable Tips: Both ends have identical threads, making it easy to swap or replace worn tips (replacement tips: 6767‑B for the point, 6767‑A for the fork) without buying a whole new tool.

Overall Length 145mm: Provides a balanced combination of stability and maneuverability, allowing precise force control for fine work.

Knurled Handle: The handle features an anti‑slip knurling, ensuring a secure grip even when hands are oily, preventing accidental slips that could scratch the watch case.

FAQ

Q1: What is the difference between the 5767‑F and 6767‑F? Which one should I choose?
A: Both are dual‑end spring bar tools with nearly identical functions. The main difference is the handle material: the 5767‑F has a lightweight black anodised aluminium handle, providing better ergonomics for prolonged use. The 6767‑F has a nickel‑plated brass handle, which is heavier and more durable. The tips are interchangeable between both models. Choose based on your weight preference and budget.

Q2: Can I fit thicker tips (e.g., 1.0mm point and 1.2mm fork) on the 5767‑F?
A: Yes. The 5767‑F uses the same threading as other Bergeon tips. You can purchase replacement tips such as the 6767‑A fork (approx. 1.2mm) or 6767‑S fork (approx. 1.4mm) and a corresponding thicker point. However, a point that is too thick may not fit into very narrow lug holes.

Q3: My hand slips from the handle when turning the fork – how can I improve grip?
A: First, wipe the handle clean with a lint‑free cloth to remove any oils. If the knurling has worn down over time, wear anti‑static finger cots or cotton gloves to increase friction during use.

Q4: If the tool slips frequently when removing spring bars, could it be due to worn tips?
A: Yes. If the fork ends become rounded, they tend to slip off the spring bar; if the point becomes blunt, it may fail to engage the spring bar shoulder properly. Replace the tips as soon as frequent slipping is noticed.
