The yellowing and clouding of the clear parts of a skeleton model due to ultraviolet light is unavoidable. It becomes a different kind of charm from the original shine. It feels nostalgic, like memories seen through slightly clouded glass. The black dial floating in the clear case tightens the overall look and exudes a quiet presence. The case and black – it's like a boundary connecting the past and the present. When you wear it, you'll suddenly be enveloped in a nostalgic mood, and the scenery in your memories will gently breathe back to life in your hands. It's that kind of watch. The battery is new. Silicone grease applied. *Battery replaced on October 26, 2025 You can use it with confidence. The troublesome time setting has been done, so you can use it as is.
