Hello, I received a pocket watch that belonged to my great-great-grandfather, William Shemwell Parran. I was able to open both sides (it opens in the front and back. A third opening at the back houses the movement. I'm ashamed to say I know nothing about pocket watches, and would love some advice on how best to take care of this one. It is engraved with 14K on both sides, and has some very detailed (curvy) writing on one side, which I'm guessing are Will's initials. The other side has the same scroll-type writing, which reads "1892." The watch is not marred in anyway (it had been stored lovingly in a box and forgotten about for about the last 70+ years). The inside reads "A.W.W. Co. Riverside Waltham, Mass. Adjusted, safety pinion. 4268221. I wasn't expecting it to tick, but I wound it slightly and discovered that it runs like a champ. I wondered if there is any significance to the numbers (serial number?) on the inside of the watch? Any illuminating thoughts would be appreciated. I took some pictures, and will upload them to my computer in a day or two. Thanks!
