This piece came from my aunt's estate. It looks like she may have used it very little if at all as it is in pristine condition. I took it to a jeweler and they took it apart. It's clean and rust-free inside except for the sperm whale oil gunking up the works. So it doesn't currently work but most likely will start with a good cleaning.
It's a 1962 ladies model #483 maunal wind Swiss watch in 18K white gold. Let's say early 1960s, but I'm fairly sure 1962.
It came from Sweden.
