Battery replaced and working. Sometimes the chronograph second hand doesn't move, and it has deviated from its original position, but the deviation could be corrected by pulling the crown out one step and using the lower right button. Once corrected, the second hand and the small upper right 1/10 second hand also start to move normally. The inner circumference of the belt is slightly deformed in one place, but I don't think it's a concern. Other than that, it's in beautiful condition with no noticeable scratches. The inner circumference of the belt is about 16.2cm and is elastic. I think it's a rare model. Thank you for your consideration. SWATCH CHRONO Swatch Chronograph Virtual Green Swatch. Ref.
