working watch! so cool. the watch was tested with a gold tester to be 14k gold but the back has been engraved so the original stamp is gone. There is a picture of the inside of the back plate where is says "b&b favorite 25 years" which notated gold fill in antique watches. here is some more info on it: A "B&B Favorite 25 years" refers to a vintage gold-filled pocket watch case made by Bates & Bacon (B&B), where "Favorite" was the grade, signifying it was guaranteed for 25 years, meaning the gold plating was expected to last at least that long without wearing through, indicating a higher quality case.
the watch is engraved with a beautiful pattern around the face and monogrammed on the back. what a wonderful piece of history- coming in at around 100 years old and still ticking! the watch and band are in good shape, the band has no identifying marks. I added a picture of the informative I found on the watch based on the serial number
