  • Oura Develops Smart AR Glasses Controlled by Smart Ring

    Oura Develops Smart AR Glasses Controlled by Smart Ring

    Key Takeaways

    1. Oura’s new patent (20260023426) outlines how wearable devices, like a smart ring and smart glasses, could connect and work together.
    2. The smart ring can collect heart rate data, which can be displayed instantly on the smart glasses, helping users adjust workout intensity.
    3. Users can manipulate the display on the smart glasses through hand gestures using the linked smart ring.
    4. The patent mentions potential applications in augmented reality (AR), mixed reality (MR), and virtual reality (VR), but clarifies that displaying heart rate data is not the same as full visual overlays.
    5. The technology is still in the patent stage, and it is uncertain if it will become a marketable product by mid-2025.

    In a newly released patent numbered 20260023426, Oura shows how various wearable devices could connect and work together. The company specifically mentions a smart ring and smart glasses in their plans. While this idea isn’t exactly revolutionary, the patent explains how heart rate data collected by the smart ring could be shown instantly on the smart glasses. This feature could help users adjust their workout intensity easily. Moreover, the display can be manipulated through hand gestures, thanks to the linked smart ring.

    XR Applications Mentioned

    The patent also touches on XR applications, which may include augmented reality, mixed reality, and virtual reality. This could mean adding virtual elements to real-world settings, although these terms are sometimes misused in practice. Simply put, displaying heart rate information is an extension of reality, but it doesn’t equate to visual overlays seen in real life, like translating a menu in a restaurant.

    Future of the Patent

    At this moment, it’s just a patent. It suggests that Oura has been developing this type of technology at least until mid-2025. As is often the case, it’s uncertain whether this idea and patent will eventually become a product that can be bought.

  • Wearables to Accurately Estimate Blood Sugar Levels Ahead of Apple

    Wearables to Accurately Estimate Blood Sugar Levels Ahead of Apple

    Key Takeaways

    1. Actxa’s smart ring estimates future blood sugar levels using AI and optical sensors, but results are not precise measurements, only a dynamic range after a one-minute assessment.
    2. The press release does not provide details on the extent of the dynamic range, which may limit practical use if it is too broad.
    3. The smart ring includes a “medical-grade” assessment for the risk of developing type 2 diabetes based on data collected over three days.
    4. The effectiveness of the risk evaluation may depend on both PPG sensor data and activity data, but specifics are unclear.
    5. The blood glucose estimate feature is not suitable for individuals with type 1 diabetes or those experiencing hypoglycemia and should not replace traditional blood testing or continuous glucose monitoring (CGM).

    Actxa has introduced a smart ring that aims to give an estimate of blood sugar levels in the future, though measuring blood glucose without invasive methods has been quite challenging. To fully understand how this feature is intended to function, the related press release needs to be examined closely.

    How the Technology Works

    The company claims to utilize AI and optical sensors to offer insights into blood glucose levels. It’s important to note that “insight” does not equate to precise measurement. Instead, a dynamic range is expected to be shown after a one-minute assessment. The press release lacks details on how extensive this dynamic range is. Generally, reporting values as a range is acceptable when precision is not possible, and scientific measurements often convey uncertainty in ranges. However, if the ranges for blood sugar are excessively broad, they may not provide practical information.

    Risk Evaluation Features

    Furthermore, the smart ring offers a “medical-grade” evaluation of the risk for developing type 2 diabetes. This assessment relies on data gathered over a span of 3 days. It’s not clear how much the PPG sensors contribute to this evaluation, as it could also depend on activity data. The manufacturers state that the blood glucose estimate should not be used by individuals with type 1 diabetes or those experiencing hypoglycemia, indicating that this feature is certainly not a substitute for traditional blood testing or continuous glucose monitoring (CGM).

As for the PRG-69B-1, its pricing and availability remain unannounced, but it’s expected to be in the same price range. These watches are likely to reach global markets, including Europe, around March. As previously mentioned, they are already available for preorder at the French retailer David et Philly for €200, with a shipping date set for March 20.

The new timepieces feature H500 solar and 8210 automatic calibres, with case sizes ranging from 40 mm to 43 mm and water resistance rated up to 10 bar.

    New Sports Chronographs

    The February 2026 release kicks off with the AT2137-50E and AT2137-50F, both sporty chronographs constructed from black-cased stainless steel. These watches are driven by the Citizen H500 Eco-Drive calibre, allowing for a standard 1-second chronograph function with a capacity of 60 minutes. They also include a 24-hour sub-dial and a date display positioned at 4 o’clock.

    With a case width of 43 mm and a slim profile of just 11.2 mm, this watch could serve as a daily companion for those in search of a lower-profile chronograph. The main difference between the two models lies in their design: the AT2137-50E showcases gold-plated hands and indices for a striking contrast, while the AT2137-50F features red accents on the dial for a classic racing vibe. Both models come equipped with a tachymeter scale on the inner bezel and offer water resistance up to 100 meters.

    Elegant Mechanical Models

    The latter part of the launch features four mechanical models that take on a more classic dress watch appearance, confirmed by the inclusion of Roman numerals at the 12 and 6 o’clock marks. These timepieces are powered by the 8210 automatic calibre, a movement with 21 jewels that can be seen through an exhibition case back. It runs at 21,600 vibrations per hour and has a power reserve of around 40 to 43 hours.

    These watches boast refined dial finishes and case materials. The NJ0240-55A (white dial), NJ0240-55E (black dial), and NJ0240-55X (salmon dial) all feature brushed and polished stainless steel, complemented by matching multi-link bracelets. The NJ0242-50E stands out as the flagship of the series, showcasing a full gold-toned PVD coating on the case and bracelet, along with a matte black dial. Each of the four models maintains a diameter of 40 mm and a thickness of 11.6 mm.

  • Casio Unveils Three Green Watches with 10-Year Battery, From $39

    Casio Unveils Three Green Watches with 10-Year Battery, From $39

    Key Takeaways

    1. Casio’s new “Green Dial” series for February 2026 includes three existing models: MRW-210H-3BV, AEQ-110W-3A2V, and W-218HD-3AV, marking a strategic update to their entry-level lineup.
    2. The MRW-210H-3BV features a 52.6 mm analog design, 100-meter water resistance, and a battery life of about three years, but has quicker battery depletion due to its size.
    3. The AEQ-110W-3A2V offers a hybrid analog-digital display, a 10-year battery life, and classic features like a 30-entry Telememo database, while also maintaining 100-meter water resistance.
    4. The W-218HD-3AV is the only digital model, featuring a stainless steel band, 50-meter water resistance, and a 7-year battery life, making it the heaviest model despite its smaller size.
    5. Pricing for the models is set at approximately £39 for the MRW-210H-3BV, £50 for the AEQ-110W-3A2V, and £29 for the W-218HD-3AV.

    Casio has introduced a new “Green Dial” series for February 2026, featuring three already existing hardware modules. The models included in this release are the MRW-210H-3BV, AEQ-110W-3A2V, and W-218HD-3AV. Instead of being a special limited edition, this collection represents a strategic update to the brand’s entry-level lineup.

    MRW-210H-3BV Details

    The MRW-210H-3BV incorporates an analog three-hand mechanism within a resin case measuring 52.6 mm. It is designed for high visibility as a tool watch, showcasing a bi-directional timer bezel and a day-date indicator. This model is powered by an SR927SW battery, which has an expected lifespan of about three years. Although it boasts a standard water resistance of 100 meters, the trade-off for its larger visual size is a quicker battery depletion compared to the digital models in this series.

    Features of AEQ-110W-3A2V

    For those looking for additional features, the AEQ-110W-3A2V comes with a hybrid analog-digital display. Its standout feature is a 10-year battery life, courtesy of the CR2025 cell. This model includes classic functionalities like a 30-entry Telememo database and world time support for 30 cities. At 16.7 mm in thickness, it is the bulkiest option in this series, a necessity due to the internal space needed for both the LCD and mechanical hands. Nonetheless, it retains the same 100-meter water resistance as the purely analog model.

    W-218HD-3AV Overview

    The W-218HD-3AV is the sole digital model in the lineup and features a stainless steel band with a triple-fold clasp. It showcases a traditional square industrial design and has more compact dimensions compared to the larger designs of the other two. However, there are clear compromises: the water resistance is limited to 50 meters, and while a 7-year battery life is commendable, it’s a middle ground when compared to the analog and hybrid versions. The addition of a metal band raises the weight to 85 g, making it the heaviest model even though it has the smallest case size.

    According to @geesgshock on Instagram, the Casio MRW-210H-3BV will be priced at £39 (~$53.43), the AEQ-110W-3A2V will have a retail price of £50 (~$68.49), and the W-218HD-3AV will be the most affordable option at £29 (~$39).
