Canuck, thank you for that fine post on the topic.
Came perilously close to purchasing a pocket watch when I was in Abilene, Texas at a watch shop this morning. Saw an assortment of Hamilton, Hampden, Illinois, Waltham, and Elgin watches with 17 jewel or better movements. One Hamilton with a 992 was from the 19-teens. One Illinois had a really nice looking "Springfield" 17 jewel movement in it. Not railroad grade though and even the watchmaker owner said that railroad grade pocket watches were a good place to start.
That Hamilton 992 had a bad dial. Was a double stepped (?) dial with an extra "step" between the 4 and the 5 where it had been patched. Shame as it was a Montgomery dial which appeals to me.
I am pretty sure I have a decent 16 size Hamilton dial in my spares if you decide to go back.
Some Hamilton dials have FOUR feet, and some have THREE feet. They are not interchangeable. Any 16-size Hamilton dial from an OPEN FACED watch with three dial feet will fit any other 16-size Hamilton movement meant for a movement with three feet, in open faced case. Same goes with four feet dials. Hunter case Hamilton dials will only fit a hunter cased model. How to tell three or four feet?
The images are of a Hamilton grade 992, and a Hamilton 952.
On the picture marked Hamilton 952, the arrow points at the crown wheel which is contained by two screws. The dial on the watch has FOUR feet.
On the picture marked 992, the red arrow points at the crown wheel which is held by ONE screw. This dial will have THREE feet. The dials on Hamiltons such as the examples, are NOT interchangeable.
This rule of thumb does NOT apply to 18-size Hamiltons!
I am aware of the difference and wouldn't have offered him a four foot dial for a 992.
I exposed my own ignorance there. I guess I've never dealt with an old enough 992, I thought they all used three footed dials.
Does anyone collect particularly complicated pocket watches? Not like George Daniels level but heading more in that direction with chronographs moon phase, perpetual calendars etc?
