This is a custom watch made by putting a new exterior on a used module. It has only been used twice. The bezel is from a GW-M5610U, and the adapter and belt are aftermarket products. It's radio-controlled and solar-powered (Tough Solar), so no battery changes or time adjustments are needed. The Velcro strap makes it easy to put on and take off, and I think it has a masculine look. The total belt length is 25cm, and the belt width is 22mm. It can accommodate wrist sizes from approximately 15cm to 20cm. Please note that this is a used item, and there may be minor scratches that are not visible in the photos. If you are sensitive to such imperfections, please refrain from purchasing.
