Thank you for viewing this product. My father does a lot of outdoor work, and I purchased this hoping it would have a heatstroke alert function. However, the model I selected did not have this feature, so I am offering it to someone who would appreciate it. The current Amazon sale/coupon price is 5,999 yen. I only performed the initial setup, and realized at that stage that it lacked the heatstroke alert function. I initialized it without ever using it. The language is set to Japanese. The product has never been worn. ▫️Product Name Smartwatch [2025 Industry New Release, ChatGPT Equipped, AI Watch Face, GPS Built-in] High-Brightness Flashlight, Military Grade, 2.01-inch Large Screen, Bluetooth 5.3 Calling, Sports Watch, 3ATM Waterproof, Shockproof, GPS Exercise Track Recording, Long-Lasting Battery, 100+ Exercise Modes, DIY Watch Face, Altimeter, Barometer, Compass, App Notifications such as Line, Step Counter, Compatible with iPhone and Android, Japanese Instruction Manual (Black) *I cannot post a link, so please search for it yourself.
