This is a very rare and cool watch with a black dial and a rectangular shape! It has a design taste similar to the Cartier Tank Must. The battery has been replaced at a watch store, and I purchased a new belt. I used it a few times, but I am selling it because the size didn't fit me. There are some adjustment scratches from when the belt was replaced, but I don't think there are any problems with use or appearance.
