Please add my welcome to Rob's.
You have a very nice watch! Although you didn't request information, here's what I know about your fine watch.
Please excuse me if I repeat some of what you already know, it's easier for me this way. Checking the references listed in the Elgin Watch Co.
Encyclopedia article (and looking at your pictures), Elgin movement serial number 9,860,285 can be seen to be
Adjusted to Temperature, Positions and Isochronism
having 21 jewels
and a Traveling Nut Patent Regulator
The movement is fitted with a double-sunk, Arabic dial
having a R5MT (Red 5 Minute Track).
It was built in about 1902, give or take a year or so. This was a popular movement of which 8,550 of this variation were made.
You can see a catalog description of the No. 270 grade, along with a picture and where it fits in Elgin's line of 16-size movements, on page 74 of the Otto Young & Co.
1903 OY Company Jewelry Catalog (below).
Your Watch Case
and was made by the Star Watch Case Co.
Your watch is a railroad watch
, one that was widely accepted into railroad time service
at the time it was built.
Unless you know that it has been properly cleaned and oiled within the last few years, you should have the watch serviced before running it very much. It may be helpful for you to read the Encyclopedia article on Watch Service
and its related links, especially the one to the message board thread on the subject
. The Encyclopedia article on Choosing a Pocket Watch Repair Person
may be useful as well.
Unfortunately, many of the links in our Encyclopedia articles were disrupted when we changed to the current version of our Message Board and its been a long process getting them all reinstated. So, if you come across a broken link, please report it here
Please feel free to ask about anything that isn't clear to you.
