Serial dates it at 1907-08. 17j, Adj. It has a Crescent Street style regulator but is not marked Crescent Street any where. I have not opened it up yet. It was in a OF Silveroid, swing out case with an Elk on the back. Movement is 45.80 mm. It is stem wind, Stem set but the case appears to have had a lever set in it at one time. It's very clean and runs right on time. I know the watchmaker that serviced it in 1957 but he is now 98 and does not remember much. I can not find it in the big book. Any ideas?

Patrick, Your watch is an 18s, 17j, open face, model 1883, grade 85.

Thanks Brian. Guess I'm going to have to get some more charts so I can look this stuff up myself.
