This is a genuine Panerai product. It's a limited edition color from the 2025 collection and features a quick-release mechanism. The size is 24/22mm and I used it on a 44mm Luminor. I purchased it at the Ginza boutique and it's in good condition as I've only used it a few times. I will not include the receipt in the photos as it contains personal information, but I've attached a photo of it to confirm when I purchased it from the boutique. Please feel free to ask if you have any questions.
