This is a genuine Mandarin Orange strap for a Rolex Chameleon, originally set in the diamond bezel box. It's a very rare color, with white leather backing and no stitching. This stitch-less type in this color is relatively rare, so I highly recommend it. The color is officially Mandarin Orange, not just orange, and it's from the first edition. I decided to offer it because it's perfect for summer. The gold foil crown and ROLEX lettering are also very beautiful. As it's from the initial set for the bezel models, the thickness is carefully measured. It seems to have accurate thickness and width, so it shouldn't be difficult to fit into any watch case. Being an early strap, it's of high quality and should fit any watch. This item is new and unused. As mentioned, it's an original set strap, and because it was included with a diamond bezel, which tends to have a slightly narrower strap opening, it's less likely to be too thick, catch, or have poor sliding. It's genuine, so it slides well and is made of shiny calfskin, making it very sturdy. The colorful, vitamin-like color is perfect for adding a pop of color. I tried it with a buckle without a crown, and it fits perfectly, showcasing the quality of the original. There are no cracks or stickiness, and it has been treated for mold and water repellency, and has been maintained. I believe this strap is in a condition that will allow you to use it for a long time. For those who own diamond bezels or star dials, which are known to have narrower openings, this strap is particularly suitable. This is the Mandarin Orange color, among the initial sets, including Etoupe Grey (rare), Purple (to be listed), a very beautiful off-white, and white. It's different from the usual orange and is very close to Hermès orange. WG and YG buckles with crowns are also available; please inquire if you wish to purchase one. I will sell it. Please refrain from purchasing if you are overly sensitive, as it has been stored at home. I will sell it to those who understand the nature of antiques. *The buckle is not included in the listing.
