The CZ Smart MX1017-50X offers comprehensive health tracking including heart rate, SP02, fitness activity, and sleep monitoring. It also uses the YouQ app to learn your unique Chronotype and provide personalised alertness forecasts.

The Citizen CZ Smart stands out with its unique YouQ app, developed with NASA and IBM AI, offering personalised wellness insights. While many smartwatches offer similar core features, the YouQ's focus on Chronotype and daily rhythms provides a distinct advantage for users seeking optimised daily potential.
What is the battery life of the Citizen CZ Smart MX1017-50X and how quickly does it charge?
The Citizen CZ Smart MX1017-50X offers over 24 hours of battery life, though actual usage may vary. It can achieve a full charge in approximately 40 minutes, allowing for quick power-ups throughout your daily routine.

Editor's take
The Citizen CZ Smart MX1017-50X represents a compelling entry into the competitive smartwatch market, leveraging Citizen's brand recognition with a feature-rich digital platform. This 44mm stainless steel model is clearly aimed at individuals who prioritise comprehensive health and activity tracking alongside seamless smartphone integration. Its round case design offers a familiar aesthetic, making the transition from traditional timepieces to smart wearables more approachable for many users.
Under the hood, the CZ Smart is powered by Wear OS by Google and a Qualcomm 4100+ chipset, providing a fluid user experience and access to a broad ecosystem of applications. Key technical features include integrated GPS, Wi-Fi, NFC, Bluetooth, and a suite of advanced health sensors such as heart rate and SP02 monitoring. The inclusion of a gyroscope, altimeter, and accelerometer further enhances its capability as a robust fitness and outdoor companion, tracking various metrics with precision.
While the watch offers a strong feature set, its "Water Resistant" rating and IPX6 certification indicate protection against powerful water jets, but not necessarily suitability for swimming or diving. Users seeking a smartwatch for extensive water activities might need to consider models with higher water resistance ratings. The 24+ hour battery life is standard for this category, though heavy usage of GPS and other sensors will naturally reduce this duration.
Ultimately, the Citizen CZ Smart MX1017-50X is an excellent choice for those seeking a versatile, stylish smartwatch that excels in health monitoring and smart connectivity. It's particularly well-suited for users embedded in the Google ecosystem or those who appreciate the CZ Smart YouQ app's personalised wellness insights. For individuals prioritising extreme durability or deep-water capabilities, exploring dedicated sports watches or higher-rated dive computers might be a more appropriate alternative.
