This is a new and authentic Bergeon 5700-52 professional watchmaking tool set. It includes 9 aluminium suction dies with soft Adiprene heads designed for safely opening watch case backs without scratching or damaging the surface.
These suction dies are unused and come in the original Swiss-made case, clearly marked with the official product labels. Each suction die is precision-made and designed to grip securely across a range of case sizes.
If you are not sure if this will fit your watchmaking needs or if you have any other questions, feel free to email me at Sales@TheWatchLink.co.uk. I'm happy to help!
