- 1Colors may vary and change over time with use. Not all colors available in all regions.
- 2Recycled aluminum is at least 4% of product based on weight.
- 3Requires 4G LTE wireless service plan (sold separately) to use cellular functionality. Compatible cellular service and roaming may not be available on all carrier networks or in all areas. For full talk, text, and data functionality, Google Pixel Watch and Android companion devices must use the same carrier network. Contact carrier for details about current restrictions, network performance, compatibility, and availability. Watch connects to compatible 4G LTE networks but 4G LTE service, speed and performance depend on many factors including, but not limited to, carrier network capabilities, device configuration and capabilities, network traffic, location, signal strength and signal obstruction. Actual results may vary.
- 4Requires compatible device. Accuracy dependent upon distance, orientation, signal obstruction and other factors.
- 5Google Pixel Watch is not compatible with Android (Go edition). See g.co/pixelwatch/specs for technical and device specifications details.
- 6Not available for all apps or content.
- 7Maximum battery life is approximate and is based on testing conducted in California in 2025 on pre-production hardware and software, using default settings with a median Pixel user battery usage profile across a mix of talk, data, standby, and use of other features the use of features that are default in Battery Saver mode. Battery life depends on features enabled, usage, environment and many other factors. Use of certain features will decrease battery life. Actual battery life may be lower. Over time, Pixel software will manage battery performance to help maintain battery health as your battery ages. See g.co/pixelwatch/batteryhealth for more information on battery life.
- 8Based on use of in-box USB-C® Quick Charge Dock with 30W adapter (sold separately) plugged into a wall outlet. Actual results may be slower. Charging speed based on testing with fully drained device batteries. Charging testing in 2025 on pre-production hardware and software using default settings with the device powered on. Charging speed depends upon many factors including battery age and ambient temperature.
- 9Storage specifications refer to capacity before formatting. Actual formatted capacity will be less.
- 10Not available in all countries. Blood oxygen measurements, when available and enabled, are intended for general fitness and wellness purposes and are not intended to diagnose or treat any medical condition or for any other medical use, including self-diagnosis or consultation with a doctor. Please consult your doctor before beginning or modifying any exercise regimen or making health-related decisions. Use of the blood oxygen sensors may decrease battery life.
- 11The ECG app is only available in select countries. Not intended for use by people under 22 years old. See fitbit.com/ecg for additional details.
- 12Like all heart rate tracking technologies, accuracy is affected by physiology, location of device, and your movements and activity. Some uses may require the Fitbit mobile app.
- 13Some uses may require the Fitbit mobile app. Use of the cEDA sensor may decrease battery life.
- 14Not available in all countries. Significant changes in ambient temperature may negatively impact skin temperature tracking.
- 15Google Pixel Watch is designed to comply with a water protection rating of 5 ATM under ISO standard 22810:2010 and with a dust and water protection rating IP68 under IEC standard 60529 when each device leaves the factory, but it is not waterproof or dust proof. Water resistance and dust resistance are not permanent conditions, and will diminish or be lost over time due to normal wear and tear, device repair, disassembly or damage. Google Pixel Watch is not drop/impact proof and dropping your device may result in loss of water and dust resistance. Damage from drops, impacts, and other external forces are not covered under warranty. Google Pixel Watch is designed to be used in shallow water and should not be used for activities involving water at high velocity or high temperature. Some Google Pixel Watch bands are not water-resistant. See g.co/pixelwatch/water for details. After any exposure to liquid, we recommend drying the watch and band because, as with any wearable device, it’s best for your skin if the band is clean and dry.
- 16These recycled materials are at least 9% of product based on weight.
- 17Docking, speaker, and haptic magnets contain 100% recycled rare earth elements, but the majority of the magnet weight consists of other materials.
- 18Recycled tin is at least 80% of the solder paste based on weight.
- 19Based on retail packaging (excluding adhesive materials) as shipped by Google. To meet the request of some clients, plastic stickers are applied to some packaging variations.
