Frequently asked questions
Samsung announced Heart Health Score in June and left out the part where it will not produce a number until you calibrate it against a cuff you do not own.
The declaration lists the Classic by name but gives it no model number, no date and no price. Anyone who wants the rotating bezel is still buying the Watch8 Classic.
Tom's Guide wore it two weeks and measured 60 hours of battery. Samsung fixed the dive rating and left the case just as chunky.
If you own the Watch 4 Classic and want a bezel that still turns, the Galaxy Watch 8 Classic is now the only one.

One of the four is not an addition. Heart Health Score replaces Vascular Load, the metric Samsung introduced with the Galaxy Watch 8.
Three generations on one squircle, no rotating bezel this year, and Samsung's own teaser pointed at the inside instead.
The case is the same 47mm titanium squircle. What moved is 12% of its thickness, a bezel font and a strap texture.
Jason C put Snapdragon Wear Elite in the Ultra 2 on 1 May. Samsung confirmed it 82 days later, without the part number.
A cellular watch is corrected while you run. Every other model waits for Wi-Fi or your phone, so the map improves afterwards.
Two beta builds turned up on Samsung's servers hours apart, for the Galaxy Watch 8 and the Galaxy Watch 7.
Gemini now opens over your watch face instead of taking the whole screen. Version 1.36 is rolling out, but Google switches the glowing new animation on from its own side.
Ninety-four minutes on a 45W brick, more than four hours on Samsung's own 25W adapter. The only thing that changed was the wall charger.
Galaxy Aero would run a real-time OS, priced between the Fit 4 and the Watch FE. The Galaxy Fit 3 runs the same software for almost two weeks a charge.
Distance and heart rate matched across all three trackers. Only the calorie figure split, and Google's help page already carries reports of it.
Galaxy Watch owners can finally save images from its browser. Took only five years.
Samsung Health v7.0 is reaching Galaxy Watches with a redesign, but sleep apnea detection, Heart Health Score and Fitness Index need One UI 9 Watch.
Samsung promises five Wear OS updates to 2031 on the Galaxy Watch 9 and Ultra 2, two more than the Pixel Watch gets, and the Watch 8 is unlikely to be included.
