This Smartwatch Uses NASA Tech To Judge Your Wellness

Citizen introduced its second-generation CZ smartwatch at CES 2023 and is using NASA technology to measure when you'll be tired in the next 24 hours.

You'll get this AI-powered advanced health information in the Citizen Smart YouQ app, which features what the company calls a "self-care advisor."

The NASA division is successful when it passes the Alert Monitor test, which Citizen says is based on NASA's psychomotor alert test for astronauts. It may not sound like much fun, but the process is "written" to make it seem less labor intensive.

This test provides a measure of vigilance, which can be an interesting way to quantify when your brain isn't fully engaged.

There's an even more interesting piece of Citizen CZ watch software. After "seven to ten days", the clock will process its timeline.

This is a profile that represents your natural sleep patterns in relation to your circadian rhythm. This tells you if you are more of a morning or afternoon person.

Citizen says this profile will be based on "alert scores, timeline, sleep patterns, activity, and heart rate monitoring" and not just whether or not you wake up late.

Power Fixes are an integral part of this process. you'll get tips on how to deal with that frustrating silence before it happens. Fitbit offers similar functionality in sleep profiles that were added to Fitbit Premium in mid-2022, hiding timers behind cute giraffe, bear, dolphin, hedgehog, parrot, and turtle avatars.

In addition to this software, the second generation Citizen CZ smartwatch technology is known. This is a Wear OS watch with a Snapdragon Wear 4100+ chipset and 8GB of storage.

Sensors include a barometric altimeter and blood oxygen sensor, as well as standard GPS, heart rate sensor, and motion sensors.

Battery life is rated at a typically boring '24+' hours, and there are 41mm and 44mm options, though both have 1.3-inch OLED screens.

The two sizes have completely different design characteristics, with the larger being much more structured and more like a diver's watch. They are called the Sport (44mm) and Casual (41mm) lines.

Citizen says the second-generation CZ smartwatch will be available in the US starting in March 2023. Casual watches will cost $350, while the larger 44mm sports models will cost $375. This is slightly lower than the original price of the first Citizen CZ watch of 2020, which sold for $400.
