When I retired from the RAF I duly handed over my Hamilton issue watch. The young lady storesperson asked if I had removed the battery. My reply that it was a wind up watch produced a look of puzzlement. I had not used it for years relying on my faithful Seiko Belmatic . Her attempt to find it and other items on the computer proved fruitless as I pointed out much of it was issued before the advent of such devices.
I am sure others can relate similar tales.
