Purchased in 2019. Used daily as a watch and also used the GPS function during marathon races. The battery still lasts for 1-2 weeks. * Depending on usage I think it's in relatively good condition, but the band, in particular, shows some signs of aging, so please understand this before purchasing. ---------- Here's some reference information: A 100m water-resistant, shock-resistant digital watch with a heart rate monitor and GPS function. - Brand: GARMIN - Model Name: INSTINCT - Water Resistance: 100m - Shock Resistance: MIL-STD-810G - Functions: Heart rate monitor, GPS - Color: Black - Country of Manufacture: Taiwan
