Top developments
Apple Developing Screenless Fitness Band to Compete with Whoop
Apple is building a screenless health and fitness tracker to rival Whoop's wrist-worn device, according to Bloomberg reporting from late September. The tracker is part of Apple's effort to rethink its smartwatch lineup and introduce new wearable technologies. Apple executives including services chief Eddy Cue—who now leads Apple's health teams—are involved in the project, though the company has not decided whether to take the device past the prototype stage.
Oura Faces Privacy Backlash Amid IPO Delay
Oura has delayed its IPO plans following growing privacy concerns around AI wearables and health data collection. The delay reflects broader industry backlash against wearables' data practices, as companies including Apple, Google, and Meta push new AI devices amid heightened consumer scrutiny.
Sleep Staging Accuracy: Oura and WHOOP Confirm Leadership
Recent peer-reviewed validation studies show Oura Ring Gen 3 achieving 76–79.5% sensitivity and precision for sleep stage discrimination, while WHOOP 4.0 reaches 69.6% sensitivity. Apple Watch Series 8 achieved 50.7% sensitivity in the same cohort (Schyvens study), and Fitbit Sense 50.9%. A 2024 University of Tokyo study examined Oura Ring Gen 3 with the updated Sleep Staging Algorithm 2.0 (OSSA 2.0) against polysomnography gold-standard across 96 participants and 421,045 thirty-second epochs.
Huawei Launches Sapphire-Glass Watch in Japan
Huawei announced the HUAWEI WATCH FIT 4 with sapphire glass display on October 5, 2026, shipping the same day in Japan. The move emphasizes durability and premium positioning in a crowded market.
DC Rainmaker Apple Watch Series 12 Review: Mixed Upgrade Signal
Independent reviewer Ray Waliton (DC Rainmaker) published an in-depth review of the Apple Watch Series 12 three days ago, examining whether the sensor upgrades and new health features justify an upgrade. The review signals consolidation around health metrics as the primary differentiator across major platforms.
Local view
Japan (Smart Watch Life & Kakaku): Japanese tech media flagged Amazon sales momentum on October 2–3, with Apple Watch, CASIO, Fitbit, Galaxy Watch, Garmin, Huawei, Polar, and Suunto models on sale at up to 32% discount. Smart Watch Life editors highlighted cloud security vulnerabilities in the context of the 2020 Garmin ransomware incident, signaling renewed privacy awareness among Japanese consumers.
Context & numbers
Market consolidation: CNET's updated "Best Fitness Trackers of 2026" (published 8 hours ago) ranked devices across multiple price tiers, underscoring Apple Watch, Oura, Whoop, Fitbit Air, and Garmin CIRQA as the leading contenders. No single product has captured majority market share; segmentation by use case (running, general wellness, sleep science, medical clearance) persists.
Regulatory backdrop: FDA cleared Apple Watch hypertension notification as a Class II medical device (510(k) premarket notification K240929, updated September 21, 2026). The clearance does not require Apple to match measurement accuracy of predicates; instead, it demonstrates clinical utility for early detection. Sleep apnea notification feature also obtained FDA clearance in prior periods.
Japanese product expansion: Huawei shipped at least 6 smartwatch models (4 base designs with size variants) in its September 2, 2026 Munich announcement and is actively diversifying in Japan with premium materials.
