Here are a few of my favorites!
There are some large images on some posts, so that might impact your load times, bit I think you will find it worth the wait. Thanks for visiting!
This example features a fancy gold inlay dial and gold hands. It was made about 1901.
It's rare to see these dials without some cracking, especially in the large size, which are rare anyway.
This plate allows the winding arbor to be in either of two positions, 90 degrees different from each other.
In this image we can see a linkage of two similar parts connecting both stem positions to the "snap" mechanism for the crown to snap in and out. Among the many unique features of this movement, the "snap" is here in the movement, rather than provided by a sleeve spring in the neck of the case.
The "snap" is provided by the business in the upper left. The hunter position for the winding arbor is directly pointing left. The open face position is facing down in this image. The jewel for the lower forth wheel, which is the seconds hand, is at the upper most in the image.
The Elgin convertible models have the ratchet in between, inside, a two part barrel bridge. The trick to converting from hunter to open face is that a main wheel, which turns the ratchet wheel, which winds the mainspring, can be positioned at one side of the other inside the bridge - a 90 degree difference.
This watch is being assembled in open face mode. The stem is facing down in these images. The unused void for the hunter configuration is to the right.
Adding to its uniqueness, the winding mechanism is on the top, or back side, of the movement, opposite the dial.
When in setting mode, a pin pushes up from the other side and lefts an arm, causing a main wheel to move up, off of the ratchet wheel, and engage a wheel in the center.
The cannon pinion on the other side rides directly on the arbor of this exposed center setting wheel, thus turning the hands.Find more examples of Elgin's convertible movements here...
This one is unnamed, but it is the 21 jewel version. It's railroad grade and one of the best watches of it's time. It's always nice to see one of these.
This example was made about 1896.
These movements are usually found in hunter cases, as ladies watches.
Occasionally they are also found in very early wristwatches.

I used it here to move the stud a little. The outside end of the spring passes through a hole in the stud. A brass pin follows and is driven friction tight. The pin can be removed to adjust the stud.
This is not a real common task, and a tool like this is not used often, but when the need does come up, there's nothing like having the right thing at hand.
Such watches have a minute hand with a square hole at the end (the "boss") to fit on the hub. In this case it looks to me like a normal round-holed hand, for a stem-set movement, has had the hole filed roughly square. It didn't really fit though, and would not go on far enough to allow the use of the key.
In order to preserve as much "as found" as possible, I expanded and squared to hole a bit rather than stick a new hand, or the expected type, on there.
