This is a Royal London pocket watch. I purchased it a little over two years ago for just over 20,000 yen. It was working until April 2025, but the battery is now dead, so you will need to replace it before use. As it is a quartz pocket watch, the maintenance costs should be relatively low. It's a beautiful watch with a distinctive design on the lid. The dial also has a date display function. Thank you for your consideration.
