From a retired watchmakers a vintage Bergeon 6694, some sort of measuring tool, I have not got a clue what it is for. It is approx 450g in weight and is stamped Bergeon 6694 Swiss made Patent Pending. It stands on a plastic tray which does have some damage to the edges, but doesn`t have an effect on it working. I can only assume the plastic tray is to catch what it is you are measuring. The screw part is numbered 0-10-20-30-40-50-60-70-80-90, and when turned is on a measure which is nu...mbered 0-5-1. It is in good used condition.
