This is a 1988 model WHITE KNIGHT, model number GW110. It is currently a hard-to-find vintage item and a rare piece. I purchased it previously at an auction. The watch size is: case width 34.00 mm, case height 39.20 mm, case thickness 8.75 mm. For this listing, the battery has been replaced, and it is currently running, but ※the time is slow, so the exact time cannot be confirmed. Please consider it for display purposes or for parts. It is a used item, and there is a vertical scratch at the 1 o'clock position on the watch case, but otherwise, there are no noticeable scratches, so I think it is in good condition. The instruction manual and watch storage case are also included. ※The strap is not the original. It has been replaced with a new matte black strap. The replacement strap is a third-party product, but it is a Swatch-specific strap and is very flexible, so I don't think there will be any particular problems. Please confirm the above and consider purchasing only if you agree.
