Thank you for viewing. This is a SEIKO 5 automatic watch with a blue dial and a skeleton back. I was into mechanical watches and bought this, but I rarely used it and kept it in a case. The size has been adjusted, but the extra links are still available, so I will include them. - Brand: Seiko - Model: 7S26 Automatic - Dial Color: Blue - Band Material: Stainless Steel - Back Design: Skeleton - Date Display: Yes - Day Display: Yes
