I've recently started to get some new watches, so I've been going through my original collection. This pocket watch belonged to my Grandpa, and I received it for Christmas shortly after his passing. It had some work done to it at that time, including replacement of the crystal I believe. I don't know a lot about watches, so I've been trying to learn more of the history of this piece. A serial number search revealed that it is a size 12s, 7 jewel, grade 303, model 3, class 114 made in 1926. It features two Gryphons on the dial, and nice blued hands. I think I need to have it cleaned and serviced. Can anyone suggest a good shop to service this watch? I would like to find out more about the grade and class designations. Anyway, if you know of good references either web or print, I would like to read more about Elgin watches of this era.
