G-SHOCK GA-B2100 BL/WH CasiOak Marina Custom Bluetooth Thank you for viewing. This is a custom GA-B2100, a tough solar and Bluetooth-equipped model, customized into a diver's watch. I used it mainly during the summer, but I was careful, so while there are fine scratches if you look closely, there are no major scratches, and I think it's relatively clean. As shown in the images, I will ship it in the box that came with the G-SHOCK GA-B2100-1AER. - Brand: G-SHOCK - Model: GA-B2100 - Style: Diver's Watch CasiOak Marina Custom Band - Band Material: Stainless Steel - Features: Rotating Bezel - 4-link extension included
