This Watch is my pick for the Case below. I've reasoned that the Case belonged to an Indiana Farmer so he wouldn't need the best in "Railway" accuracy but would need a sturdy Movement. This watch is "Railroad Grade" for the time of manufacture but not a "Top of the Line", 21 / 23 Jewel, Fancy model, like the New & Special Railway's. 

This is a 3-Ball Model, 18 size, 17 Jewel, Hampden, Open Face Movement, w/ a Star Patent Regulator. The Grade designation "3-Ball" comes from the circular Damasking Pattern. 

This "Fancy" Dial is a good match for this Movement & Case Combination,with it's sentiment; "From Ma" & it's Custom Engraving on the Dust Cover.  

The Original Dial has a Arabic Script, Double Sunk, Dial, w/ a Spade Hour Hand & Whip Minute Hand & like all RR Grade Watches is Lever Set. The Dial has a Chip {repaired} @ 5:00 & 7:00 which is why I'm considering the New Dial. I've been carrying this watch for about a week & it only gained about 1 minute.
