If you’ve been waiting for a smartwatch that doesn’t freak out at a little dirt or rain — or maybe a lot of it — Black Shark thinks it has the answer. Black Shark launched the GS3 back in May 2024 and has now added an Ultra model to the lineup.
The new GS3 Ultra still uses a 1.43-inch AMOLED display with a sharp 466 × 466 resolution, but now it sits in a beefier metal frame with four chunky buttons that look like they came off a gaming accessory. Gorilla Glass with a 9H hardness rating protects the screen, and there are said to be around 270 watch faces to choose from.
Where this smartwatch really flexes is durability. Alongside the usual 5 ATM water resistance, the GS3 Ultra also boasts a full IP69K rating — the same category used for heavy-duty industrial gear. That means the watch can withstand high-pressure, high-temperature water jets. In other words: drop it, splash it, bury it in sand… it’ll probably be fine.
Health and fitness tracking is covered with over 160 sports modes, including auto-detection for common workouts like running or rowing. It tracks heart rate, blood oxygen saturation, stress, and sleep in multiple stages, and yes — it logs naps too.
Black Shark has also upgraded location tracking with dual-band GPS (L1 + L5) and support for basically every satellite network you’ve heard of: BeiDou, GLONASS, Galileo, and India’s NavIC. Calls can be taken over Bluetooth, helped by ENC noise reduction so roads and crowds don’t drown you out.
But the biggest crowd-pleaser might be the battery. Black Shark claims up to 18 days of “normal” use and as much as 45 days in standby. That’s refreshingly far from smartwatch-as-daily-charger-accessory territory.
The GS3 Ultra comes in black or silver with the same aggressive, gamer-style look Black Shark loves. Pricing and release details are still under wraps, but based on the feature list alone, this one definitely deserves a spot on the radar for anyone who routinely destroys wearables.
