Can anyone identify this antique moonphase calendar pocket watch? Inspector Byrnes is engraved on the back of the case, and in small script below "Byrnes" appears to be OB & TH. It's a large, heavy watch that is more than 2 1/2 inches wide and about 3 1/2 inches from the bottom to the top of the loop. It has 5 adjustment buttons. I bought it from someone who acquired it in a lot of items at an estate sale in New York in 1980.
