Home Watch Company

This is an 18 size Home Watch Company movement.  "Home" was a brand name Waltham used on a series of lower end products.  The serial numbers fall in line with Waltham number so one can research them using Waltham data.  

This is the Home version of an 1857 model.  

Notice that only the upper pivots are jeweled, so as to give the appearance of more jeweling than the watch actually has.

The hairspring has a clamp that screws to the plate.  The spring is not attached at all to the balance cock.  The regulator arm also sits friction fir in the plate, and not on the cock.  
This is all quite a bit different from all the Elgins I post.
