This watch belonged to my grandfather. The serial number is registered to him, but you shouldn't have any issues with that. The face plate is still in tact, but it needs to be cleaned off... Im sure the gears will need some oil as well.
The last time he serviced his watch was easily 15yrs ago. Turning the dial, all arms move except the second hand. Otherwise the watch is in good shape. I have my grandfather's horology tools and I can open it more if it helps you decide since it is in need of restoration.
