Citizen unveiled its second CZ smartwatch at CES 2023, and it uses NASA technology to predict how tired you'll be in the next 24 hours.
You'll find this advanced AI-powered health information in Citizen's Smart YouQ app, which the company calls a "self-service advisor."
The NASA department has passed the Alert Monitor test, which Citizen says is based on NASA's psychomotor warning mission test for astronauts. Maybe it doesn't look very interesting, but the process is "played" to make it seem a little tedious.
This test provides an alarm point, so it can be a fun way to identify when your brain isn't fully functioning.

There is another interesting part in the Citizen CZ watch software. After "seven to ten days" the clock will run the timeline.
This is a profile that represents your natural sleep tendencies in relation to your circadian rhythm. It tells you whether you like morning or night.
Citizen says this profile will be based on "alert results, history, sleep patterns, activity and heart rate monitoring" rather than whether you wake up late.
Energy upgrades are an active part of this process. You'll get tips on how to deal with annoying breaks, even before they happen. Fitbit added to Fitbit Premium in mid-2022 offering similar functionality in sleep profiles, hiding timers behind giraffe, bear, dolphin, hedgehog, parrot and turtle avatars.
Will the reception of citizens be easy to digest? This will be an important part of this article.
Software aside, the technology of the second-generation Citizen CZ smartwatch is familiar. It is a Wear OS watch with Snapdragon Wear 4100+ chipset and 8 GB of storage.
Sensors include a barometric altimeter and blood oxygen reader, as well as standard GPS, heart rate reader and motion sensors.
Battery life is at least typically rated at "24+" hours, and there are 41mm and 44mm variants, though both appear to have 1.3in OLED displays.
These two sizes have very different design personalities, with the larger size being more sculpted and more like a diver's watch. These lines are called sport (44 mm) and ordinary (41 mm).
Citizen says the second-generation CZ smartwatch will be available in the US starting in March 2023. The regular watch will cost $350, while the larger 44mm sports models will cost $375. Selling for $400.
