Professional reviewers commend the ScanWatch Nova for its exceptional 30-day battery, robust health suite (ECG, temperature, SpO₂) and premium dive-style construction with ceramic bezel and sapphire glass. They note the analog-hybrid aesthetic as a refreshing alternative to notification-heavy smartwatches, but criticize the tiny grayscale display, lack of built-in GPS and reliance on the app for full health insights.
Everyday users love the long-lasting battery, accurate wellness metrics and the classic analog look that disguises a smart device. Common praise centers on reliable swim tracking and overall durability, while recurring complaints focus on the heavy feel, difficulty reading the small hidden screen in bright light, occasional app sync issues, and limited notification capabilities.

Professional reviewers commend the Instinct 3 Solar for its class-leading battery endurance, rugged metal-reinforced construction, and highly accurate multi-band GPS. They also appreciate the improved solar panel efficiency and robust health-tracking suite, while noting the trade-off of a monochrome display and a bulkier form factor that may not suit users seeking a bright, sleek screen.
Everyday users love the watch's durability and the ability to go weeks without charging thanks to solar power. The reliable GPS and handy flashlight receive frequent praise, but many complain about the dim monochrome screen in shade, the watch's heft on smaller wrists, and occasional GPS or heart-rate hiccups in challenging environments.
“Long battery (weeks without charging)”
