Japanese smartwatch wena X, the smallest in the world, starts crowdfunding at GREEN FUNDING

augment AI Inc., a Japanese company recently formed by former members of the team that developed the acclaimed wena smartwatch by The innovative device, which promises to transform the experience of using wristwatches by combining technology and design, will have its crowdfunding campaign launched on the GREEN FUNDING platform from 11am on March 20, 2026, seeking to engage technology and fashion enthusiasts who value the discreet integration of smart features into classic accessories, and who will now be able to support the project via the official website or email/LINE subscriptions for the latest updates.

This initiative represents a new chapter for wena technology, which had already set a crowdfunding record in the past. The team, led by Representative Director Teppei Tsushima, assumed the trademark and patents for Grupo Sony, establishing augment AI to continue and expand the original vision.

“wena Sua proposal is to improve the practicality of a smartwatch without compromising the elegance and aesthetics of the user’s favorite watch.

Innovation and compact design

The wena series has always been based on the unique concept of a “smartwatch that can be attached to your favorite wristwatch”, and the wena X takes this premise to a new level of sophistication. Sua’s most distinctive feature is the “bi-directional” structure, enabling a fluid transition between watch style and smart bracelet style, a functionality driven by a one-touch snap-on and snap-off mechanism that currently has an international patent application.

The miniaturization achieved by the wena X, which positions it as the smallest smartwatch in the world in its category, is the result of a complete redesign. Featuring an 8.5% reduction in overall length compared to the previous model, the wena 3, the new device combines hardware and software advancements, including a new patent-pending buckle structure and an ultra-low-power, RTOS-based wena operating system.

2 in 1 experience for everyday life

The versatility of wena X allows users to switch between different wearing styles depending on the situation, optimizing both functionality and aesthetics. You can wear it as a formal wristwatch during professional or social engagements, and easily remove it to use it as a smart bracelet during physical activity or sleep, ensuring that the technology adapts to the individual’s daily rhythm and needs.

Além In addition, compatibility with strap widths from 16 to 24 mm significantly expands the universe of watches that can be attached, making the “smart experience where the watch takes the lead” accessible to an even wider range of consumers. Essa adaptability not only improves convenience, but also ensures that personal style is never sacrificed for technology, reinforcing the philosophy that the beauty of the watch should be the priority.

Premium materials and intuitive interface

The philosophy of not compromising the beauty of a wristwatch is intrinsic to the wena X, extending to its construction, materials and user interface. The device incorporates a wide, curved AMOLED screen that ergonomically adapts to the wrist, significantly increasing the display area by approximately 1.7 times. Visibility and comfort are enhanced by an ultra-compact curved battery and 3D printed circuit board assembly, which optimizes the volumetric density of electronic components.

On the outside, the wena X uses SUS316L stainless steel, a common material in Swiss watches, applied to all its metal parts. Através of advanced manufacturing technologies such as MIM and CNC, augment AI seeks a high quality texture, surpassing that obtained with aluminum or resin. Complementarmente, a DLC (Carbon Tipo Diamante) coating provides wear resistance more than five times greater than conventional IP (Ion Plating) coating, ensuring durability and a sophisticated finish.

Wena OS: battery and advanced features

The heart of wena X is its proprietary operating system, “wena OS”, built on RTOS and meticulously optimized for ultra-low power consumption, stability and real-time performance. Esta architecture allows the smartwatch to achieve an impressive battery life of one week, freeing users from the constant worry of daily recharges and providing a freer, more connected day-to-day life.

Equipped with high-precision sensors, the device offers an intuitive experience and advanced features. The three-wavelength optical heart rate sensor, combined with a high-precision motion correction algorithm, raised the heart rate detection accuracy from 86.8% to 93.3%, ensuring more reliable health data.

Furthermore, wena Planned applications include:

• Exercise and well-being
• NFC payment (under development for international brands)
• Weather forecast
• Alarm, timer and stopwatch
• Calendar and camera shutter
• Music control and “Find phone”
• Integration with ChatGPT

Sleep and exercise optimization with AI

Wena X places particular emphasis on optimizing “sleep” and “exercise”, crucial components for daily fitness, completely restructuring the recovery process. Through a strategic capital and business alliance with ACCELStars, a neurotechnology and sleep startup with roots in Universidade of Tóquio, augment AI has jointly developed an AI-based sleep analysis function for wena X.

This partnership enables a transition from simple “logging” to comprehensive sleep understanding and optimization. The device now uses sleep analytics based on medical scientific research to visualize indicators such as the four stages of sleep with high accuracy. Funções like nap detection, smart alarms, sleep scores, and detailed analytics help users regulate their sleep effectively.

For exercise, wena X supports more than 130 types of activities and automatically detects the start of exercises such as walking and running, switching to sports mode with a single tap. Ele visualiza o efeito do treino (aeróbico e anaeróbico), carga de treino, nível de recuperação muscular, VO2 máximo e idade física, fornecendo feedback valioso para aprimorar a qualidade do treino e registrar as mudanças na condição física.

wena X transcends the function of a mere daily activity tracker; it integrates sleep, exercise and recovery into a seamless experience to optimize users’ daily performance.

Reliability and national production

Recognizing that smartwatches handle sensitive personal data such as sleep, exercise and health records, wena X prioritizes “reliability” as a central pillar of the user experience. augment AI adopts an operational policy that guarantees the storage of data collected on servers located exclusively at Japão.

All management of this data is carried out internally, ensuring that collection, storage and handling are entirely under Japanese control. Essa approach not only reinforces privacy and security from the design phase, but also provides an environment where users can use their devices with complete peace of mind, confident in the integrity and protection of their information.

Special 10th Anniversary Edition

Celebrating its 10th anniversary on June 30, 2026, the wena brand launches a special and limited edition, the “wena X – 10th Special Edition -“. Este mechanical skeleton watch will be offered in exclusive pre-sale through crowdfunding, with 200 units in silver and 200 in black, at a special price, marking the launch of the wena X.

The case design prioritizes comfort while maintaining the concave dial, a signature of the original design philosophy of wena watches. With a Swiss mechanical movement SELLITA SW200-2 S b Power+, it guarantees smooth hands (8 vibrations per second) and a power reserve of 65 hours.
