Galaxy Watch Ultra2 and Watch9 Official: Thinner, Record Brightness, and Advanced Heart Monitoring

Samsung

Samsung has officially unveiled, alongside the Galaxy Z Fold8 line, the new generation of its wrist devices dedicated to fitness and health monitoring: Galaxy Watch Ultra2 and Galaxy Watch9. The Korean company continues to push the integration of high-level hardware and AI-assisted software ecosystem, offering two smartwatches designed to meet the needs of both the most demanding athletes and users looking for daily monitoring of their physical condition.

Both models introduce significant evolutions in hardware platform and efficiency, essential for ensuring continuous diagnostics 24/7 without compromising user experience. The core of both wearables is the new Qualcomm Snapdragon Wear Elite (SW6100) platform, built using a 3-nanometer manufacturing process. The penta-core architecture guarantees a distinctly higher computing speed compared to previous generations, coupled with energy efficiency that can manage data volume captured by biometric sensors in real-time.

Both models debut the new Super AMOLED panel protected by sapphire glass, pushed to brightness levels never before seen on a smartwatch. The Galaxy Watch Ultra2 stands out as an industry leader, reaching a peak brightness of 5,000 nits, designed to ensure maximum readability even in direct sunlight in high mountain areas or desert environments. The Galaxy Watch9, on the other hand, has a display that reaches an excellent threshold of 3,000 nits.

Galaxy Watch Ultra2: Record Battery Life and 'Pro' Tilt

Available only in a 47 mm diagonal with a titanium case (in Titanium Gray and Titanium Silver finishes), the Galaxy Watch Ultra2 is designed for those who engage in extreme sports or demanding outdoor activities. Despite an internal architecture redesigned to reduce thickness by 12% compared to its predecessor, Samsung engineers managed to fit a generous 800 mAh battery (+35% capacity) inside the case.

Among the standout features dedicated to sports is the triple resistance certification: 10 ATM, IP69K, and the EN13319 standard, specific for diving equipment. The smartwatch can automatically track depth, water temperature, and dive duration as soon as you go underwater. This will be complemented, by the end of the year, with the Diving for Ultra2 app, developed in close collaboration with Mares, which will enable the calculation of ascent/descent times and management of safety limits.

For runners and trail runners, advanced metrics like Nutrition Alert (which estimates fluid loss based on body weight and suggests when and how much to drink) and detailed analysis of elevation changes over uneven terrain are introduced. Geolocation is entrusted to a dual-frequency GPS L1+L5 module, ensuring precise tracking even in deep gorges or dense forests.

KEY SPECIFICATIONS OF GALAXY WATCH ULTRA2:

  • Case: 47.4 x 47.1 x 10.7 mm (61.5 g) in Titanium
  • Display: 1.52" Super AMOLED, 498x498 pixels, 5,000 nits
  • SoC: Qualcomm SW6100 (3 nm, Penta-Core)
  • Memory: 2 GB RAM + 64 GB Storage
  • Battery: 800 mAh with fast charging WPC
  • Resistance: 10 ATM, IP69K, MIL-STD-810H, EN13319

Galaxy Watch9: The Ally for Daily Health

For users seeking a more classic and elegant form factor, Samsung offers the Galaxy Watch9, available in 40 mm and 44 mm variants with a lightweight aluminum case. The design echoes the appreciated cushion silhouette, refined in the rear curvature to ensure perfect adherence to the wrist and maximize the accuracy of biometric sensors.

The hardware features 2 GB of RAM paired with 32 GB of internal memory, with batteries of 390 mAh (40 mm model) and 445 mAh (44 mm model) respectively. Connectivity includes Bluetooth 6.0, dual-band Wi-Fi, NFC, LTE, and GPS.

BioActive Sensor and AI Algorithm Evolution

The turning point of Samsung's wearable offering lies in the reprocessing of vital parameters through artificial intelligence, managed by the One UI 9 Watch interface based on Wear OS 7. The BioActive sensor combines optical pulse measurement, electrocardiogram (ECG) tracking, and bioelectrical impedance analysis (BIA).

Among the main software innovations are:

  • Sleep Apnea Detection: FDA-approved, analyzes variations in saturation and respiration during sleep.
  • Vital Parameters: tracks the user’s baseline at night, notifying abnormal deviations from usual values.
  • Cardiac Wellness Score & Cardiac Load: immediate numerical assessments of cardiovascular health, with advice on recovery times and training intensity.
  • Hearing Monitoring: alerts when prolonged exposure to harmful noise levels is present.

KEY SPECIFICATIONS OF GALAXY WATCH9:

  • Case: 44 mm (34.0 g) / 40 mm (31.5 g) in Aluminum
  • Display: 1.47" (480x480) / 1.34" (438x438) Super AMOLED, 3,000 nits
  • SoC: Qualcomm SW6100 (3 nm, Penta-Core)
  • Memory: 2 GB RAM + 32 GB Storage
  • Battery: 445 mAh (44 mm) / 390 mAh (40 mm)
  • Resistance: 5 ATM, IP68, MIL-STD-810H

Prices, Availability, and Promotions

Both devices will be available for pre-order starting today, July 22, with distribution in physical stores and online platforms scheduled for August 7.
The Galaxy Watch Ultra2 will arrive in Titanium Silver and Titanium Gray colors, while the Watch9 will be available in Cream and Graphite (40 mm) or Graphite and Silver (44 mm), accompanied by a new line of straps (Marine, PeakForm, Trail, Misty, Fabric, and Sports).
Included with the purchase of the wearables, Samsung offers 60 days of free trial for the Strava service and 2 months of subscription to the guided training platform iFIT, along with the option to extend coverage against accidental damage through Samsung Care+ services.
