HectorLooi is correct. They are for removing the plugs (ends) fro cylinders. A cylinder is made up of three pieces a plug at each end and the center piece

Thanks OH. So does the pin on the face of the stake slide into the slot at the side of the cylinder and push the plug out from the inside. I think i would never use these.

Yes that is right The set I had the stakes were very thin. I don't know about the ones you posted photos can be very deceiving.

Your assumption about operation is correct.  The tampons which have the pivots are pressure fitted.  These stakes are the  safest way to remove and replace them without doing damage.  My set of Bergeon stakes look a little different.  I have repaired several cylinder escapement watches and I possess three of them.

As to never knowing if you will use them: in my experience, time will tell.  Prepare to be surprised.

yes the picture makes them look really really big I wonder if they made tower clocks with cylinders?

then they do come in a variety of sizes to correspond to the size the cylinder you have. so yes the cylinder watches could be from pocket-size all the way down to possibly a ladies wristwatch and I'm not sure that people made cylinder staking punches understood that. We had one punch in the staking set it was too big we managed to find a vintage set of bergeon ones and they were all too big and this is a pocket watch. So maybe they were designed for carriage clocks or something much bigger.

    • Hi everyone on my timegrapher it showing this do a make anymore adjustment someone let me know ?    
    • Maybe I'm over simplifying this and I'm a little late to the discussion, but just by my looking at oil when I use it on a treated cap jewel  the oil stays in one nice bubble, but when I don't it spreads out to the edges of the jewel. I'm not sure (but could well be wrong) but the analogy of a waxed car and rain is accurate in this case, the wax is very hydrophobic and repels the water, however, the process epilame works by is a different physical process based upon cohesion/adhesion (oleophilic) not repulsion (oleophobic)  at least as far as I have read/observed. If one were to use a oleophobic substance equivalent to wax (hydrophobic) then one would need to create a donut shape to fence in the oil, however if one used such a strategy with a epilame which is oleophilic then the oil would sit on the ring of the donut and not in the 'donut hole', exactly where you don't want it. Even is the oil is smeared then the oleophilic epilame should pull it back to the center (see diagram below). Reference
    • Looks lint the teeth on the hour wheel aren't meshing with the teeth on the calendar intermediate wheel, maybe the hour wheel is sitting on top of this instead of meshing?        
    • If the oil drop was freely standing on an epilame treated cap jewel it could easily slide off if you knocked the watch hard but the balance pivot keeps it in place. 
    • Latest 404 is this Baron which has a copy of a Seiko 66B movement in it, handy when I needed to find a replacement setting lever. Apart from the setting lever, crown, stem and new crystal (original was cracked) the watch is original. Finished result:
