I'm not sure of the details. I purchased it as junk. It was sold with something like the circuit board removed, and I wanted everything but that, so I bought it even though it was broken. I was told by the previous seller that it had been disassembled before. I think it can be reused for things like replacing the body if it's too scratched. The screen seems to have almost no scratches. Please judge from the photos. Sold as is. Body only. One screw was missing from the time of purchase. It seems to have been disassembled before... I haven't disassembled it myself, so I don't know the condition of the inside. Louis Vuitton Louis Vuitton Smartwatch Tambour Horizon Used, so no returns, refunds, or exchanges.
