The Vintage Casio B-815 wristwatch, manufactured in Japan in 1984, is a classic timepiece with a unique Modulo 155 design. This watch is a timeless piece of jewellery and a collector's item for watch enthusiasts. Its vintage charm and reliable functionality make it a desirable accessory for those who appreciate the craftsmanship and heritage of a well-crafted wristwatch. some very light scratches to the crystal/glass/acrylic new batter fitted two weeks ago I've kept an eye on the watches performance and it's working well
