TechRadar has published a first-person review of the Apple Watch Series 12, based on ten days of use by one of its writers. According to TechRadar, the reviewer could not stop thinking about one measurement the outlet described as slightly imprecise. The article does not specify which measurement was in question.
The review appeared on Monday, October 5, 2026, alongside other recent Apple Watch coverage from the same outlet. TechRadar also published a separate piece on the Apple Watch Ultra 4, written after a week of testing, in which the reviewer said the device looked set to become a genuinely impressive training watch.
Other outlets have weighed in on the Series 12 as well. ITavisen ran a piece suggesting many users will notice only one improvement, while Letem světem Applem focused on how the watch measures during a run against the Apple Watch Ultra 4.
Taken together, the coverage points to a familiar pattern for annual wearable releases: incremental gains that are easy to list but harder to feel, and at least one metric that draws scrutiny from testers. TechRadar's headline frames its concern as a lingering doubt rather than a failed test, and no full article text was available at the time of writing.
What to watch next: whether other reviewers report the same measurement issue, and whether Apple responds with a software update or an explanation.
