National Watch Co. Keywind Pocket Watch. Watch manufactured in 1871, 4th year of production of Elgin. This is an 18 size, Grade 57, 11 jewel, G. M. Wheeler model pocket watch. Comes with a key, when wound, takes right off and keeps reasonable time. It is housed in a silverine case and has a single sunk dial in good condition. This watch has been in storage for years and as with all watches, I recommend servicing before everyday use. Any questions, feel free to ask!
