Best Smartwatches for Fitness
We put this question to ChatGPT, Claude, Gemini and Perplexity every week — then check their pick against the people who actually used it.
Power ranking
The top products right now.
This week?
Garmin's Epix Pro Gen 2 and Samsung's Galaxy Watch 6 both climbed nine spots this week in the smartwatch fitness rankings, with the Epix Pro now at number five. The Forerunner 965 holds the top position while two new entries, the Forerunner 265 and Pace 3, landed at six and seven respectively. Galaxy Watch 5 Pro fell nine ranks to sixteen, and the Apex 2 Pro dropped eight to fourteen, signaling a shift away from last week's established favorites toward Garmin's newer lineup and Samsung's latest generation hardware.
What AI values here
GPS tracking is the foundation here, with most top picks including it to log your routes and distance accurately. Dual-band GPS and rugged builds show up often too, signaling that AI consensus values precision in variable conditions and watches that can handle harder use.

They agree, we say so. They split, we show you the gap.
Act one
What the machines think.
Three AI models read the category and rank every product. They agree on the very top — and split harder than anywhere else below it.
Model by model?
How each AI ranked it.
All three models open with the same #1 when they agree — below it their lists diverge. Each column is one model's own ranked picks; the lead pick sits a touch larger, and a lone tag marks a product only one model chose. The board below merges them into one machines-only top 10.

What reviewers say about Forerunner 965 for this question
Reviewers praise its fitness tracking and GPS accuracy but note it excels at nothing individually and costs more than capable alternatives with better battery life.
- Multi-band GPS maintains industry-leading accuracy across swim, bike, run activities
- Comprehensive training metrics including chronic training load, wrist-based running dynamics, and unified training status sync across devices
- Battery life falls short of transflective models like the 955 or dedicated endurance watches

Beyond this question
Where the winner shows up elsewhere.
context & history
You want a watch that tracks your miles and your heartbeat without becoming a burden on your wrist. The trade-off is simple: battery life versus screen size. Most people chase features they'll never use. What matters is whether the thing stays on your arm for days and gives you the data you trust.
The strong options separate on two points. Some watches run for a week on a charge and strip down the display to save power. Others give you a bright screen and a smart phone in miniature, but drain the battery by nightfall. Apple Watch dominates the smartwatch side. Garmin and Coros hold the fitness tracker side, where durability and battery win over bells. Pick based on what you'll actually look at each morning and whether you'll remember to charge every night.
