I may be wrong but I did one of those last year. The case back was incredibly tight and I had to use one of these.

where did you obtain that beast?

I use a Stanley knife blade to open my Rotary. Just enough to create a gap to use the normal case opener.  It is well machined and no gap to insert anything but not that tight once it starts moving.

I purchased this tool a few years ago. i think at the time Cousins was selling them. I have seen them on ebay. If you want a more slick tool and have a bigger budget horotec do this.

   I have had a problem with some of those "nifty tools"  made of  "chinezium".  the design is excellent and the steel is soft.  vin

bought one of these(above) and struggled a bit until i took the blade off and used that on its own and hey presto it opened.next shock; there was no battery in the movement(?) my mate said he paid a jeweler friend £9 to fix it! i think he needs a visit!! could be he got confused.i will find out.any way the problem is now sorted for a couple of  quid:mad::woohoo-jumping-smiley-emoticon:

i see you edited your post,but i saw it first in my e-mail box! it is a ronda movement.thanks.B.

Ah yes, edited because I re-read your post and realised it was now working.

Didn't know Rotary used Ronda. Is it a recent model? The ones we have in the family are all Miyota but about 7 to 10 years old.

    • A helpful way in aid of assembly is to place all the wheels in their respective places, place to plate on the top and fit a couple of the nuts onto the pillars. This stops all the wheels wobbling about as they are lightly held by the plate, you can manoeuvre the pivots into their holes, using a tool , usually home made or can be bought on eBay. I made my own. As the pivots align and fall into place screw the nuts down a bit to keep up the tension on the plate untill all wheels are in place then tighten down sufficiently to keep the plate in place whilst checking the end shake on ALL wheels and their location when all is good only then tighten down the plate.
    • I'd say my Pultra 10 lathe. It is just so well made and everything fits so tightly together.
    • Welcome to the forum, enjoy. 
    • Yes, the specific old tools do exist, but may be having one is not needed as they are not cheap, and also You will be able to do without it well enough. My advice will be to use regular depthing tool and adjust it for the exact distance between pallet fork and escape wheel bearings from the watch. Then remove the shellac from the pallet that now doesn't pass the ew teeth and move this pallet in. Then put the pallet fork and ew on the depthing tool and check how they lock. They should not lock when the pallet is in, but You will little by little move the pallet out and locking will appear. Then move just an idea out for reliable work and apply shellac, then check if things are still the same. You have to observe where the teeth fall on the pallets - it must be just a little below the edge between impulse and rest planes. Then You must check how everything behaves in the movement This Potence tool is so ingenious, but actually, the traditional way to do the things is much more simple. Arrange the parts not on the pillar plate, but on the cover plate. Only the central wheel will remain on the pillar plate, secured by the cannon pinion.
    • There is a tool that was made for setting up and adjusting escapements of full plate watches.  There were two styles, the picture below shows both of them.  The lower tool held a movement plate and the vertical pointed rods were adjusted to hold the unsupported pivots of the lever and escape wheel.  There was also a version of this tool that had 3 adjustable safety centres so that the balance pivot could be supported by the tool :  The other version I’m aware of is the Boynton’s Escapement Matching and Examining Tool came as a set of two or three clamps that gripped the watch plate and held the safety centres for the pivots : These do turn up on eBay from time to time.  For some escapement work, you can set up the parts in a regular depthing tool, with the centres set according to the distance between the corresponding pivot holes on the movement.  I hope this helps, Mark
