The smaller and lighter Series 12 can fit thin wrists more securely than the heavier Ultra, which may also help sensor consistency.
Pros: value for money, heart rate accuracy
Cons: data privacy
Fit was praised in one outdoor-focused review for staying secure during daily use and activity.
Pros: battery life, voice assistant quality
Cons: value for money, mapping and navigation
Fit is generally good thanks to slimness and size choices, though one reviewer with smaller wrists found the larger case somewhat big.
Pros: battery life, value for money
Cons: coaching features, recovery insights
Fit mattered for sensor performance; the Sport Band was praised as adjustable and effective for running accuracy.
Pros: charging speed, display quality
Cons: battery life, water resistance
The large Ultra case can fit comfortably for some people, but thin or average wrists may need a tight strap for reliable heart-rate readings and can find the size excessive.
Pros: battery life, value for money
Cons: data privacy, comfort
Fit evidence was limited and mixed, with one reviewer saying the older body did not sit as flush as the Series 11.

Fit had a specific concern: the Trail Loop worked loose enough to affect sensor contact.
