·A new arrival here. A 1923 Hamilton 920, 23 jewels, sapphire pallet jewels, ruby pivot jewels, gold train and center wheel, adjusted to five positions, in a 12s 25 year warranted case. All in all, one fine timepiece. The dial is slightly damaged but it really doesn't present badly in person.
The skinny on @Waltesefalcon ’s slick Hamilton grade 920. Add lever setting to that, and it would be railroad grade, but not railroad approved because it is a 12-size. Safety mainspring barrel. What can you tell us about the case material?

I have included an image of the19-jewel version of the grade 920. This one is a grade 902, but it is virtually the same movement as the 920, except for the jewel count. I did this one for a friend several years ago.
