battery
320 mAh, roughly 1-2 daysWith typical daily wear use (checking time, occasional notifications), expect one to two days between charges; heavy activity shortens it to less than a day.
charging
Wireless Qi only, no wired optionYou'll need a Qi charger pad to top up; no cable charging means slower refill but works if you leave it on a dock overnight.
display
1.43 inch AMOLED, 60 HzSmall square screen is sharp at 461 ppi and will look crisp for watch faces and text, but 60 Hz means scrolling through lists feels standard, not smooth.
durability
IP68, fully submersible to 1.5mSealed against dust and water down to 1.5 meters for 30 minutes, so it survives daily splashes, pool days, and accidental dunks.
