1987 Model / SWATCH / Gent / GI400 / Blue Note A valuable vintage Swatch Blue Note. I put in a new battery and tested it, but it did not work. Time adjustment is possible by turning the crown. I am selling it cheaply because I don't know if it can be repaired. The body is still beautiful! The band is old but still usable! No returns or exchanges. In accordance with Mercari's policy, I will ship it without a battery. Thank you. Operation: Good
