FREE: Man's work watch

I'm sorry but i really don't know. I had it several years and forgot and the name is not anywhere on the watch. it has the date on the front also i forgot to mention that. it says water resistant 100 ft and on the back it says stainless steel back .. base metal bezel ... PT 787 .. PC 32 ... battery # 377 ... Japan movement .... PCM... it has a small arrow pointing where you remove the back for battery replacement. i used it several years and was disabled in an accident so it's pretty old that is why i replaced the battery and let it run several weeks before i put it up to make sure it still keeps the correct time and it does. wish i could take better pictures but my camera is auto focus and won't focus that close. actually i used it for work that's why it was put up. . it's in pretty good shape it's solid and keeps the right time that's why i called it a work watch. any thing else i can answer please let me know thanks for stopping by.. oh yes and btw i have no idea what the numbers mean i just put down everything that was written on the front and back.
