Here the movement is placed on a movement holder, and is ready for disassembly.
Checking again the measurements I made to start the sketch of the case.
The dial side of the movement, with its gears.
The balance bridge is taken off, and balance wheel left.
An interesting thing are the 'dimples' that a previous watchmaker made. This is to raise the bridge ever so slightly, as there was probably an issue with the balance staff pivots.
Removing the balance staff jewels to check if they are OK. They are indeed and it is a good sign.
The balance staff jewel cap is off.
The underside of the balance bridge.
The balance ready to be examined.
At a first look the pivots seem to be both bent in one direction.
And they are slightly out of truth. This resulted from the watch being dropped at some point in its past history.
The escapement bridge, with its shape of a sickle- This is a traditional English watch trait.
Case holding screws- these are the screws that fasten the movement to the case, they are terminated in pointed ends.
Mainplate screws, as you can see here, the four 3/4 plate bridge screws are also finished with pointed ends- another very traditional facet of English watchmaking, you rarely if ever see this in a Swiss watch.
The gear train of the watch.
These are the hour and minute wheels from the dial side.
The underside of the 3/4 plate bridge. Note the three 'dots' on the right hand side, this is a maker's mark to note where it goes with the mainplate.
Checking if the mainspring barrel turns true.
It appears that it does turn true on its hub, further testing with the balance wheel in place is necessary at a later point (i.e., checking the mainspring under tension).
Another view of the escapement bridge together with the distinctive escape lever, which functions on two levels (jewels and impulse slot), and the escape wheel.
These are the banking pins which control the amplitude of the escape wheel movement (by limiting the action of the escape lever during the balance wheel swing). This is a traditional English watch trait as well.
The 'Right Angle' seen in the three jewel holes, which defines an English 'right-angle' escapement. The bottom jewel hole is the balance, the one at the top is the escape lever, and directly tangental t this is the escape wheel jewel hole.
Removal of the winding ratchet. Some restoration of the winding gears will be necessary to remove the rust.
The movement disassembled.
The center wheel and the mainspring barrel, showing the Geneva mainspring safety stop. An interesting things that the barrel cap has 3 different openings, usually it's customary to have only one. Maybe this was done by a watchmaker at some point. I will investigate why.
The mainplate jewels show lots of oil that has dried out, this will be cleaned thoroughly.
The top of the balance bridge. During cleaning the index regulator arm will also be removed.
Inspecting the pivots of the gear train. This is the center wheel driven by the mainspring.
This is the third wheel.
And the fourth wheel that has the long pinion (above one) which takes the second's hand.
