This is a GARMIN DUAL POWER watch with waterproof and shock-resistant features. I purchased it this year and used it for about two weeks, but it has been stored since then. As it is a multi-functional model released by Garmin this year, it feels very good to use, and its appearance differentiates it from common smartwatches. - Brand: GARMIN - Model Name: DUAL POWER - Color: Black - Features: Waterproof, Shock Resistance
