Vintage 1971 Bulova Accutron Man’s Watch- Please Read

I know nothing about watches. I purchased this in a lot from another seller who informed me of its value. I took it to the jeweler’s and had a new battery put in on 1/9/26. It has kept perfect time; however, the jeweler advised me that the stem was corroded & stuck so the date & time weren’t set There isn’t a local watch repair place so I’m just selling this “ad is.” I did research trying to loosen a stuck stem & tried the suggestion of a drop of WD-40 but it didn’t work. It only loosened the adhesive on knob which then pulled off. It screws back on but comes off easily so I’m not sure if I stripped it. I did a lot of research and interestingly found that Elvis Presley owned the same watch. (Not this one, of course).

According to research, this is a Model 2182. The watch band is stamped, “Hirsch Wild Boar.”
