Gaboratory 7.5mm Marine Chain Bracelet [B-312] I've been using this for about a week. The length is about 21cm, and it fits perfectly for a wrist size of 16-16.5cm. Gaboratory's anchor chain is characterized by its angular design, similar to the early Chaine d'Ancre links. You can customize various details when ordering, but I had the anchor bar made with a simple design. This is an attempt to recreate the early Chaine d'Ancre links in a 7.5mm size. I'm selling it to organize my belongings due to a move. Order price: 67,000 yen Please check the details in the photos. The [number] at the beginning of the product name is a management number, so please don't worry about it. If you have any other questions, Please feel free to ask m(_ _)m
