This is a Casio 【LINEAGE】 watch. As a bonus, I'm including a "titanium belt" and a "CASIO LINEAGE LCW-100T Radio Solar Titanium" watch. I purchased this watch and used it for a while. While it has many scratches overall, it has a vintage feel, and the scratches that accumulate during use add to its character. I'm selling it because I bought a new watch and have less opportunity to use this one. I hope to pass it on to someone who will cherish this watch for its "flavor" as well. The watch functions without any problems, but the light button is a bit stiff. There is no instruction manual, but it can be viewed on the Casio official website. The bonus titanium belt is a third-party generic product purchased from Amazon and is considerably lighter than the original stainless steel belt. Please feel free to use it. Please refrain from purchasing if you are concerned about minor scratches or signs of use, as this is a used item. Negotiations for a discount are possible if you are seriously considering a purchase, so please feel free to comment.
