Thank you for viewing. This is a Weekly Auto Orient Swimmer case, rarely seen on the market, with a 30-jewel cut glass (inner side of the glass) specification. I really liked its high-end feel, waterproof function, and beautiful design at the time, and I was planning to use it myself after an overhaul. However, I am listing it this time to organize my collection. I am not sure about the detailed accuracy, but it is a working product (automatic winding), and the crown operation and quick date change mechanism worked without any particular problems. I am not sure about the overhaul history, so I recommend an overhaul if you are considering daily use. As it is an old model and a home-stored item by an amateur, please check the photos carefully and purchase with your understanding. ※This is only listed from the Mercari account, so please be careful of sales on other sites.
