Garmin Quatix 8 specifications and in-depth review

Garmin Quatix 8

Manufacturer: Garmin

The Garmin Quatix 8 is a feature-rich sports watch designed for users who demand detailed tracking and broad connectivity in a single wrist-worn device. It carries a 1.4″ OLED/AMOLED screen protected by sapphire glass, with an always-on display mode and a pixel density of 458 ppi. Weighing 92 g with dimensions of 51 × 51 × 14.7 mm, it pairs a tactile touch screen with a 32 GB internal storage capacity and compatibility with both iOS and Android platforms.

On the technical side, the Quatix 8 is rated at 10 ATM water resistance and is explicitly designed for diving as well as golf, while its sensor suite covers GPS with fast lock, heart rate monitoring, pulse oximetry, barometer, gyroscope, compass, accelerometer, and body temperature tracking. Battery endurance reaches up to 29 days in smartwatch mode and 84 hours with GPS active, supported by a rechargeable non-removable cell. Connectivity options include Wi-Fi, NFC, ANT+, Bluetooth, and Galileo support, complemented by a comprehensive Garmin app ecosystem offering live tracking, coaching, maps, voice feedback, and extensive health metrics such as HRV tracking and VO2 max measurement.

Pros
  • Sapphire glass display offers strong scratch resistance for outdoor and water use
  • Battery lasts up to 29 days in smartwatch mode and 84 hours with GPS active, supporting extended use between charges
  • Comprehensive sensor suite includes GPS, heart rate monitor, pulse oximeter, barometer, gyroscope, compass, and body temperature sensor
  • Designed for both diving and golf, with a swim stroke counter and multi-sport mode covering a wide range of activities
  • 32 GB of internal storage allows maps and other data to be stored directly on the watch
  • Rated at 10 ATM water resistance, making it well suited for aquatic activities
Cons
  • No wireless charging support, requiring a physical connection every time the battery needs to be replenished
  • Lacks a cellular module, meaning the watch depends entirely on a paired phone for any connected features
  • Does not include a cadence sensor or wind speed sensor, which may be limiting for certain cycling or sailing use cases
  • No external memory slot, so storage cannot be expanded beyond the built-in 32 GB
  • Training mode battery life of 18 hours may be restrictive during very long endurance events
  • At 92 g and 14.7 mm thick, the physical size and weight may feel substantial on smaller wrists
Who is this for?

The Garmin Quatix 8 is well matched to serious outdoor and water sports enthusiasts who need a watch that can handle demanding conditions without compromise. Its 10 ATM water resistance and dedicated diving support make it a natural fit for swimmers, divers, and sailors, while the broad sensor suite — covering GPS, barometer, compass, and body temperature — serves hikers, trail runners, and multi-sport athletes who rely on accurate environmental and navigation data. Users who spend extended time away from charging points will also appreciate the 29-day smartwatch battery life and 84-hour GPS endurance, and the 32 GB of internal storage with uploadable maps suits those who venture into areas without reliable connectivity. The watch additionally caters to golfers and those who want detailed health oversight, including HRV tracking, VO2 max, readiness scores, and a full suite of sleep and recovery monitoring tools.

Who is this NOT for?

Users who prefer a lightweight, low-profile wrist presence are likely to find the Garmin Quatix 8 impractical, as its 92 g weight and 14.7 mm thickness can feel bulky, particularly during everyday wear or on smaller wrists. Those who rely on cellular connectivity for standalone use — making calls, streaming, or receiving notifications without a paired phone — will find the absence of a cellular module a significant limitation. The watch is also a poor fit for cyclists or sailors who specifically depend on a cadence sensor or wind speed sensor, as neither is present. Additionally, users who prefer the convenience of wireless charging will face friction, since the watch requires a wired connection every time it needs to be charged.
