Which sports watch brand looks after you best?
A comparison of nine sports-watch companies judged on after-sales support, software updates, repairs, warranties, data practices and financial health as of 29 September 2026.
Useful takeaways from this story.
Polar is the only brand with a written five-year support commitment for devices.
Coros publishes clear paid repair options and refurbished swap policies beyond warranty.
Garmin is financially strongest among dedicated sports-watch makers but makes no written long-term support promise.
The useful part
One thing I'm including is a brand assessment because when you buy a sports watch, you are buying more than just the piece of metal/plastic in your hand. Garmin now owns TrainingPeaks, so rival brands that sync with TrainingPeaks now feed your training into a platform run by a competitor. Its auditor also drew attention to the company's going-concern discussion in the 2025 accounts.
How it works
- Samsung promises 5 OS upgrades and 5 years of security patches on the Watch 9 and Ultra 2, the longest published promise.
- Google forced Fitbit owners onto Google accounts, and has deleted unmigrated data since 15 July 2026.
- Suunto grew revenue 27% to 106.5m euros in 2025, but it cut research spending by 31% and staff by 22%.
- Garmin is the most financially secure of the dedicated sports watch makers, with $7.25bn in revenue and over $4bn in cash.
- It makes no written promise about how long it will support a watch you already own.
What to take from it
Coros has the clearest repair deal: a battery for $59 to $89, a screen for $79 to $119, or a refurbished swap, up to three years after the warranty ends. Garmin, Apple, Samsung and Google give 1 year in the US and rely on consumer law for the second year in the UK and EU. Every point answers one of nine questions, such as whether the company will still support your watch for as long as you own it, and whether it treats your data as yours.
