Our flagship screenless fitness tracker models — purpose-built for ODM & OEM partners in Chicago and across North America.
Over 10 years of production experience
Founded in 2016, Guangdong Eternity Electronics was born with a clear core mission: to become the world's trusted source factory for screen-free fitness trackers and craft smart wearables that blend practicality, quality and customizability — empowering brands to stand out in the fast-evolving wearable market with unique, user-centric products.
So what have we achieved since then? We've grown into a go-to manufacturing and R&D partner for global businesses, specializing exclusively in high-quality, fully customizable screen-free fitness trackers, alongside premium health monitors and smart wearables. Rejecting one-size-fits-all solutions, we focus on what we do best: bringing to life tailor-made screen-free fitness trackers (and beyond) that align perfectly with your brand's vision and your customers' needs — just like the functional, distraction-free design of WHOOP, and far more custom iterations.
Chicago's health-tech ecosystem is booming. Here's why local brands are choosing ODM screenless fitness trackers to lead the market.
With over 2.7 million residents and a deeply rooted sports culture — home to the Chicago Marathon, CrossFit communities, and hundreds of boutique fitness studios — Chicago represents one of the largest consumer markets for wearable fitness technology in the Midwest. Local retailers, gym chains, and wellness startups are actively seeking private-label fitness trackers to differentiate their offerings and build brand loyalty.
Chicago is headquarters to major corporations including Boeing, United Airlines, McDonald's, and Morningstar. These enterprises invest heavily in employee wellness initiatives — and screenless fitness trackers like WHOOP-style bands are increasingly distributed as part of corporate health benefit programs. ODM manufacturers allow HR tech companies and wellness platforms to white-label these devices under their own brand at scale.
Chicago's world-class medical institutions — including Northwestern Memorial Hospital and Rush University Medical Center — are exploring continuous biometric monitoring for patient recovery and sports medicine. Screen-free trackers that monitor heart rate, SpO2, sleep quality, and HRV provide clinical-grade data without the distraction of a traditional smartwatch display, making them ideal for clinical trial wearables and rehabilitation monitoring.
The global fitness tracker market is projected to surpass $114 billion USD by 2028, growing at a CAGR of over 15%. A significant share of this growth is being driven by screenless, minimalist wearables — inspired by the success of WHOOP — that prioritize continuous biometric monitoring over notification-heavy smartwatch features.
Consumers and enterprises alike are shifting toward devices that track health metrics 24/7 without interrupting daily life. This "invisible tech" philosophy — where the device disappears into your lifestyle — is reshaping product design priorities across North America, Europe, and Asia-Pacific markets. Chicago-based brands are at the forefront of adopting this next-generation wearable category.
As an ODM manufacturer with deep R&D investment in 6-axis motion algorithms, ECG sensing, SpO2 monitoring, and body composition analysis, Eternity Electronics is uniquely positioned to help Chicago brands ride this wave — with fully customizable hardware, firmware, and companion app solutions.
How Chicago brands and organizations are leveraging ODM screenless fitness trackers across multiple verticals.
Chicago Bears, Chicago Bulls, Chicago Blackhawks, and Chicago Cubs training staff are increasingly adopting wearable biometric tools for athlete load management and injury prevention. ODM fitness bands with 6-axis motion tracking and HRV monitoring provide coaching teams with actionable data. White-label solutions allow sports franchises to deploy branded devices across their entire roster.
Institutions like the University of Chicago, Northwestern University, and DePaul University run active kinesiology and public health research programs. Screenless fitness trackers serve as non-invasive data collection tools for longitudinal health studies. Our ODM models support custom firmware for research data export, making them ideal for academic partnerships and clinical research applications.
Chicago's growing insurtech and healthtech startup scene — fueled by organizations like MATTER health accelerator — is creating demand for branded fitness trackers tied to wellness incentive programs. Insurers can reward policyholders with lower premiums for meeting activity goals tracked by white-label ODM bands, creating powerful engagement loops and reducing long-term claims costs.
