Q1: What is the Bergeon 6670 used for?
A: The Bergeon 6670 is a hand vice designed to hold bracelet screws securely in place while you tighten or loosen them. It is especially useful for Rolex‑style bracelets where the screw is held on one side while you turn the opposite screw.
Q2: What is the blade size of the Bergeon 6670?
A: The blade is 1.80 mm wide with flat parallel sides, designed to fit common bracelet screw slots.
Q3: Why do I need a tool like this? Can’t I just use a screwdriver?
A: On many bracelets (e.g., Rolex Oyster), the screw is held in place by a threaded tube on the opposite side. Without holding the opposite side, the screw will just spin. The Bergeon 6670 holds the opposite side securely so you can turn the screw without damaging the bracelet.
Q4: How do I adjust the turntable height?
A: The turntable has three preset height levels: 0 mm, 0.5 mm, and 1.0 mm. Select the level that brings the screw axis into perfect alignment with the blade axis.
Q5: Does the tool come with spare cushions?
A: Yes, the Bergeon 6670 includes spare cushions for both the upper and lower parts. These cushions protect the watch case and bracelet from scratches.
