Job Number 160257

Here is a grade 81, 18 size, 13 jewels, made about 1883. 

This watch had a very loose roller jewel, shown here near the center of the underside of the balance wheel. Amazingly, the jewel was in there, on the roller table, and not lost. But all the shellac was loose.

This pocketwatch movement has the seconds dial 180 degrees from the 12:00 mark. That makes it an open-face movement in a hunter case (a hunter case is one with a front cover). A hunter movement has the seconds dial 90 degrees from 12:00.

The two types of movements exist so that 12:00 will face up when placed in the corresponding case. A hunter movement in an open-face case is usually called a side-winder because the stem will fall at 3:00. See some examples here.

This watch has an open-face movement in a hunter case. Or is it? Careful observers will notice that this is a key-wind, key-set Elgin. The crown does not even turn. This movement has no place for a stem from the case to go in. The orientation of the movement does not matter at all.

It's not the movement that is open-face style. It's just the dial that is.

The orientation of the movement in the case is dictated by a pin in the edge of the movement that goes into a hole in the inside edge of the case rim. The location of that hole orients the movement. And some cases of this type indeed have a hole in two locations, 90 degrees apart, for just this situation.
