  • Thin and Eco-Friendly AirTag Alternative with Cellulose Battery

    Thin and Eco-Friendly AirTag Alternative with Cellulose Battery

    Key Takeaways

    1. Nimble introduced four new tracker options as alternatives to Apple’s AirTag, including a keychain, luggage tag, passport holder, and card wallet.
    2. These trackers are compatible with both Apple’s “Find My” network and Google’s Find Hub.
    3. They feature an integrated, eco-friendly cellulose-based battery that offers wireless charging via a Qi pad.
    4. The new battery is slimmer than traditional coin cells, measuring just under 0.04 inches thick and is claimed to be biodegradable.
    5. Details about battery lifespan, release dates, and pricing for the new trackers have not been disclosed.

    At CES 2026 in Las Vegas, Nimble introduced four new options as alternatives to Apple’s AirTag, which is priced at $24 on Amazon. Each of these new trackers uses similar technology but features distinct designs. The collection includes a keychain tracker that resembles the AirTag, along with a luggage tag, a passport holder, and a wallet designed solely for cards, which doesn’t include a coin section.

    Compatibility and Unique Features

    These trackers are compatible with both Apple’s “Find My” network and Google’s Find Hub, allowing users to connect them easily whether they have an iPhone or an Android device. One standout aspect of these trackers is their integrated battery. It offers the convenience of wireless charging via a Qi pad, and it’s also a novel cellulose-based battery. This so-called “paper battery” has been created by Flint Labs and is currently in mass production.

    Battery Specifications

    The battery resembles a typical coin cell but is remarkably slim, measuring just under 0.04 inches thick. For comparison, the CR2032 coin cell found in the Apple AirTag has a thickness of 0.13 inches. Flint Labs claims that this cellulose-based battery is more eco-friendly than traditional lithium batteries and even asserts that these batteries are biodegradable, though specific details regarding their materials have not been disclosed.

    Nimble has not shared information about how long these batteries will last or their overall lifespan in the new trackers. Additionally, there has been no confirmation on the release date for these four new trackers that utilize Flint Labs’ batteries, and the official pricing remains uncertain as well.

  • Casio MR-G G-Shock: Inspired by Traditional Japanese Pagoda

    Casio MR-G G-Shock: Inspired by Traditional Japanese Pagoda

    Key Takeaways

    1. Casio has launched the MRG-B2100D-2AJR, a luxurious addition to its ultra-premium collection, reflecting fine Japanese watchmaking.
    2. The watch design is inspired by the Hagurosan Gojunoto pagoda, featuring a hanadai-iro finish that symbolizes the pagoda at dawn.
    3. The MR-G construction includes 27 individual parts for the bezel, showcasing exceptional craftsmanship and attention to detail.
    4. Made from advanced materials like Cobarion and DAT55G titanium alloy, the watch maintains G-Shock’s durability standards with features like shock resistance and Tough Solar charging.
    5. The G-Shock MRG-B2100D-2AJR is priced at ¥572,000 (~$3,632) and will be released in Japan, with potential for future global availability.

    Casio has welcomed 2026 by updating its basic range, introducing the enchanting GA-2100K series that reflects nightlife vibes, while also bringing back several beloved G-Shock models equipped with improved LED backlights. Now, the renowned Japanese brand is turning its focus towards its ultra-premium collection. After numerous leaks in the past weeks, Casio has formally launched the MRG-B2100D-2AJR, a luxurious watch that exemplifies the finest in Japanese watchmaking skill.

    Inspiration Behind the Design

    The new timepiece draws its inspiration from the Hagurosan Gojunoto, a five-story pagoda known as the oldest in the Tohoku area and recognized as a national treasure. This influence is prominently seen on the dial, which sports a hanadai-iro finish, a classic indigo hue historically linked to samurai armory. Casio states that this shade aims to mirror the pagoda at dawn, enveloped in morning fog. The blue tint, applied through a vapor deposition technique, changes subtly with light and perspective, symbolizing the mystical flow of time related to the pagoda.

    Fine Craftsmanship and Construction

    The careful attention to detail and build quality highlight why the MR-G is at the pinnacle of the G-Shock series. Typically, the bezel is crafted as a single piece, but this one is constructed from 27 individual parts. The bracelet’s dimples are also formed from separate pieces, with each part meticulously polished by expert artisans to achieve a flawless mirror-like sheen.

    Beneath the indigo face, the dial features a structure inspired by “Kigumi,” which is a traditional Japanese woodworking method that creates wavy patterns and tiny holes, letting light reach the solar cells for energy. Casio claims this elaborate craftsmanship employs Yamagata Casio’s advanced micro-machining technology.

    Material and Features

    The top bezel of the MRG-B2100D is crafted from Cobarion, a high-hardness alloy that boasts a platinum-like shine (reportedly four times harder than pure titanium), while the bracelet is made from DAT55G titanium alloy for enhanced resilience. Casio has integrated its Multi-Guard Structure along with internal buffers to ensure that all this sophistication adheres to G-Shock’s renowned rigorous shock-resistance criteria.

    This watch offers the latest MR-G features along with G-Shock’s promises of durability, including Bluetooth connectivity, Multiband 6 for automatic time adjustments, sapphire glass with an anti-reflective coating, a shock-resistant body and crown to safeguard the module, Tough Solar charging, and an impressive 200-meter water resistance. Plus, it includes a white LED backlight and standard timekeeping functionalities.

    The G-Shock MRG-B2100D-2AJR is priced at ¥572,000 (~$3,632) and is set to hit the shelves in Japan later this month. While there’s currently no information regarding its global availability, it’s reasonable to expect that the watch will be released internationally. If and when that occurs, we’ll ensure to keep you updated.

  • Fitbit App Update: New Sleep Metrics Coming Soon

    Fitbit App Update: New Sleep Metrics Coming Soon

    Key Takeaways

    1. Introduction of New Sleep Metrics: The upcoming Fitbit app update will include new sleep metrics, such as Sleep Need, which provides a detailed breakdown of individual sleep requirements.

    2. Understanding Sleep Debt: Another new metric, Sleep Debt, will help users assess their energy levels based on sleep history, indicating if they need to rest more.

    3. Changes in Tab Organization: The app may revert to a tab structure that includes dedicated Fitness and Sleep tabs, moving away from the current three-tab layout.

    4. Beta Testing of Features: Both new sleep metrics were previously tested in the Fitbit Personalized Sleep Schedule Lab, indicating readiness for wider release.

    5. Uncertain Release Timeline: The release date for the updated app version remains unknown, with the current version only mentioning bug fixes and performance improvements.

    A significant update seems to be coming soon for the Fitbit application. Recently, two new sleep metrics and a revamp of the tab organization were found in the code of the Fitbit app version 4.60, which was released in early January 2026.

    New Sleep Metrics

    According to Gadgets and Wearables, users of Fitbit devices may soon have access to extra sleep metrics in an upcoming update. For instance, owners of devices like the Fitbit Charge 6 (curr. $99.95 at Amazon) can already monitor their sleep duration, stages, and schedule, along with a calculated Sleep score. It appears that a new feature called Sleep Need is being developed. Lines in the app’s code suggest that this metric will provide “a detailed breakdown to explain how your sleep need was calculated”.

    Understanding Sleep Debt

    Another new sleep metric is Sleep Debt. The code for the Fitbit app includes phrases such as “Less than usual may mean you’ve built up some ‘sleep debt’, and you may want to take it easy”. This indicates that this score will help users understand their current energy levels based on their sleep history. Both of these features were beta tested in the Fitbit Personalized Sleep Schedule Lab last year.

    Potential Tab Structure Changes

    In addition to these metrics, the app’s tab structure may be getting an update. Right now, the app consists of three tabs: Today, Coach, and You. This layout was introduced in an August 2023 redesign. According to another report from Gadgets and Wearables, the app’s code shows signs that dedicated Fitness and Sleep tabs could be brought back. Just to remind you, before the 2023 update, there were four tabs: Today, Fitness, Sleep, and Health. How these tabs will be organized in the future remains uncertain. Additional clues pointing to a design change include onboarding messages like “Ready to explore your new redesigned app?”.

    It’s still unknown when Fitbit will release this new version of its app for iOS and Android users. The change log for version 4.60 on both platforms simply mentioned that it included “bug fixes and performance improvements”.

  • Seiko Launches New Presage SPB537 Inspired by 1895 Timekeeper Design

    Seiko Launches New Presage SPB537 Inspired by 1895 Timekeeper Design

    Key Takeaways

    1. The Seiko SPB537, also known as SART013 in Japan, is inspired by the company’s first pocket watch, the “Timekeeper,” from 1895.
    2. The watch features a white enamel dial crafted by experienced artists, with design elements reminiscent of the original pocket watch, including elongated black Roman numerals.
    3. It has a sturdy stainless steel tonneau case and a multi-link bracelet, designed for a classic dress watch look, with water resistance of 5 bar (50 meters).
    4. The SPB537 is powered by the Caliber 6R5H movement, visible through an exhibition case back with a gold-finished rotor.
    5. Unlike many high-end Seiko models, the SPB537 is part of the regular Presage collection and not a limited edition, although pricing and availability details are not yet available.

    Seiko has broadened its Presage lineup with the new SPB537, known as SART013 in the Japanese market. This watch features a tonneau shape and draws inspiration from the company’s historical beginnings in watchmaking. It serves as a formal homage to the “Timekeeper,” the first pocket watch crafted by the Seikosha factory back in 1895.

    Elegant Dial Design

    The standout feature of the SPB537 is its white enamel dial. To guarantee the durability and shine of this finish, Seiko has brought in the skills of seasoned enamel artist Mitsuru Yokosawa. Kazunori Uchiyama, who has learned Yokosawa’s unique firing methods, oversaw the production of the dial, ensuring high quality.

    The design of the dial closely resembles that of the original from the 19th century, showcasing elongated black Roman numerals and a railway-style minute track. While the original “Timekeeper” was a pocket watch, this modern version is designed for the wrist, featuring blued steel hands and a crescent-moon counterbalance on the second hand.

    Sturdy Case and Bracelet

    The SPB537 boasts a stainless steel tonneau case with proportions that are well-suited for a classic dress watch. It comes attached to a multi-link stainless steel bracelet that combines brushed and polished surfaces. To protect the dial, a dual-curved sapphire crystal is used, and the watch has a water resistance rating of 5 bar (50 meters).

    Inside, the SPB537 is driven by the Caliber 6R5H, part of Seiko’s high-performance 6R series. The movement can be admired through an exhibition case back, which features a gold-finished commemorative rotor.

    Standard Release

    Notably, the SPB537 is being added to the regular Presage collection rather than being released as a limited edition, which is common for many of Seiko’s higher-end models. As of now, specific pricing and availability information has not yet been revealed.
