Cannon Pinion Remover (Bergeon 4854 & Bergeon 30637-2)

In this video I will show you in detail the Bergeon 4854 & Bergeon 30637-2 cannon pinion removers.
I will disassemble the Bergeon 4854 cannon pinion remover, show you the individual parts and then assemble the tool.
The Bergeon 30637-2 cannot be disassembled but I will show you the tool in detail.
Then I will remove a cannon pinion that’s 1.35mm in diameter using both tools and I will also remove cannon pinion that’s 0.97mm in diameter.
At the end I’ll share my opinion about these two tools and tell you which one of them is the more practical tool for watchmakers if they only want one tool.
