I only tried it on after purchase. It's like new. This is a masterpiece that has won the Good Design Award. I want to sell it quickly, so I'm offering it at a low price. The following is quoted from the manufacturer's website: This is a Bluetooth®-equipped model of the MT-G, which features advanced technology in a shock-resistant body that combines metal and resin. The lugs that connect the band and the pipes are integrated, and the "core guard structure" protects the module. Carbon fiber reinforced resin is used for the center case, achieving both weight reduction and shock resistance. The MT-G series' first mid-size design and soft urethane band improve wearability, and the connection between the case and band has a vibration-resistant structure. Mirror polish is applied to each edge of the metal parts, and hairline processing is applied to each surface to pursue beauty. The case has been black IP treated. The use of sapphire glass and the delicate engraving by Casio Yamagata factory's processing technology enhance the texture. It connects to the dedicated app "CASIO WATCHES" via Bluetooth® communication to obtain time information. It also has practical functions such as a high-intensity LED light and world time, and these can be stably driven by "Tough Solar". Included items: Box, warranty Operation: Good Scratches/cracks: None
