This is a special collaboration model with rag & bone. I purchased it used and have been storing it. I don't know of any other watches in Casio's premium series that use sapphire glass. They rarely appear on the used market, and I believe this watch will continue to increase in value. The design is the biggest appeal. It uses a 5-row metal bracelet, and this one has a gunmetal and orange color scheme, which I think is the coolest among Casio watches. I haven't come across a digital watch that's cooler than this. I used to own the black model, but this one is more versatile for everyday wear and matches any outfit. The inverted LCD display is honestly a bit difficult to read, but the excellence of the design is superb. Surface treatment: Black IP (band, case) ◇ Condition of the item As you can see in the photos, there are scratches on the case back, but there are no noticeable scratches on the other parts of the case or bracelet. It is currently adjusted for a wrist size of 17cm, but I will include all the extra links, so please adjust it yourself. It will be shipped in the original box. Thank you. Operation...Good
