The Frodsham pendant sized movement, bottom side, ready for disassembly.
The front (top or dial side) of the movement.
First thing I check, is the wobble of the mainspring barrel, pointed at here by the tweezers.
In this first image, blurry, you can spot a space betwen the teeth an the mainplate.
Here, the space is considerably less, the barrel almost touches the mainplate itself.
Removing the top mainspring ratchet bridge, once can see that there is a very slight rubbing of the ratchet onto the bridge.
The movement sans mainspring ratchet bridge.
The chronometer-grade rectangular hairspring block. It is very rare to see this present in a movement of this size.
Swiss-styled double roller, also reserved for chronometers, and rare to have it in a pendant sized watch.
Escapement, there is residue build up on the escape wheel (seen near the top pivot).
Escape wheel, hee we see the bottom side with the pinion.
Exquisitely polished and finished escape lever.
Visibile here is the very large bottom-mounted gold safety impulse pin.
Another detail of the pin, which is screwed in place.
Very curved and playful escapement bridge from the bottom side of the movement (rests under the balance wheel).
There is some debris visible in the jewels.
Now I need to remove the mainspring ratchet wheel.
It is held in place by a pin, as is normal, to the mainsprinb arbor.
However, since the pin is cut off nearly flush to the arbor, I need to turn a pusher to remove it.
This is a slow process as if the pusher slips it risks rubbing on the ratchet wheel, and ruinign the finish.
Adding to the stubborness of the pin, is that it is made from steel, and not brass as it is common in this application.
Examining the barrel for any rubbing, and none is visible.
Looking at the bottom of the 2-3 plate for signs of rubbing.
They would be where indicated, but there are none visible.
There are no visible signs of rubbing of the barrel onto the mainplate either. This is positive.
Instead, under the center wheel, there is a groove, which might imply the center wheel wobbles.
However, it is probably a piece of hard dust that caught on the bottom of the center wheel and was dragged, since there is no visible damage to the bottom of the center wheel.
Typical shape of 2-3 bridge screws, with the pointed conical ends.
Another aspect that is distinctively English are the 6-spokes of the gear train. Swiss uses 5.
The beautifully shaped 1-3 dial side gear train bridge.
A look at the bottom of the mainplate, with the mainspring barrel removed.
No visible rubbing, and a very large and beautiful brass bushing (you see a steel disk in the interior, because I was checking any play in the Mainspring ratchet arbor, which appears to be none).
Visible on the side of the mainspring barrel is a round steel dot, which is where the mainspring is anchored to.
The brass pin on the upper portion of the rim is locator, so that when the lid is placed back, it is fit in the correct place.

The only place I found a bit of rust, was under this spring, and it is very light. Will not effect any visible portions of the movement.
Mainpsring barrel, ratchet wheel, and one of the springs.
A look at the underside.
And upper side of the movement. Further dissassembly is to follow.
