Ultrahuman Healthcare Pvt Ltd, a global health technology company from India, released the smart ring "Diesel Ultrahuman Ring," created in collaboration with Italian apparel manufacturer DIESEL, on Wednesday, December 10, 2025.
This model brings together the comfort and scientific data for understanding body condition that Ultrahuman has cultivated through its expertise in developing wearable devices.
It is a specially designed smart ring born from the fusion with DIESEL's distinctive brand worldview, which is loved around the world.
The "Diesel Ultrahuman Ring" was designed under the supervision of Creative Director Glenn Martens (@glennmartens).
It achieves both a high-fashion design and functionality in an ultra-lightweight body of a minimum of 2.4g.
The specifications are on par with the existing model, "Ring AIR," which is recognized worldwide.
Many positive reviews for "Ring AIR" have been received, such as "Amazing," "Great piece of Kit for tracking your health and Bi," and "Powerful insights, useful for rest... not as useful for."
The "Diesel Ultrahuman Ring" supports users' health by measuring and analyzing their daily heart rhythm, heart rate graph, and sleep rhythm, and provides practical advice, such as suggestions for adjusting their internal body clock.
Furthermore, based on sleep data, it visualizes parameters such as at what time you should consume caffeine so you can stay refreshed throughout the day without compromising the quality of your sleep.
Coffee and energy drinks support activity during the day, but excessive consumption can lead to health damage and interfere with comfortable sleep.
Having advice on the appropriate timing, which differs for each individual, is helpful even for heavy gamers.
Most current healthcare wearable devices are either smartwatches or smart rings.
While smartwatches offer advantages such as messaging, calling, and music playback through linkage with a smartphone, the smart ring's greatest appeal is its overwhelming lightness.
Since it hardly affects sleep at all while reliably tracking your health status, this is likely a long-awaited product for users who cannot sleep soundly while wearing a wristwatch.
The "Diesel Ultrahuman Ring," which breaks the common notion of smart rings having a non-descript design, was released simultaneously worldwide on Wednesday, December 10, 2025!
It comes in two colors: Shiny Silver and Distressed Black, and the price is 499 USD.
The product can be purchased on the "Diesel Ultrahuman Ring" Product Page, the official DIESEL online store, and at some DIESEL direct stores!
Please inquire with the stores regarding exhibition and sales schedules at direct stores.
Please note that the ring sizes for the "Diesel Ultrahuman Ring" are different from typical sizes.
For your first purchase, you must measure your appropriate size using the sizing kit, which is delivered for free, then specify your size and wait for the product to arrive!
