Apple Watch Series 12 is a major upgrade to the core health and fitness tracking wearable. That’s because of the new Health Sensing System that includes an even more capable heart rate monitor.

Revisiting Apple Watch Edition: Hands-on with the white ceramic Series 5

August 21, 2026: Apple Watch Series 12 is rumored to include a ceramic option for the first time since the Series 5 was discontinued. With that in mind, I’m resharing my hands-on post of my favorite Apple Watch from September 2019. Seven years later, it’s still the best version I’ve ever owned. I hope you enjoy!


Apple Watch Series 5 introduces the return of the ceramic Edition after being notably absent from the Series 4 lineup. That means this is the first time ceramic has been an option with the redesign that debuted last year, and the new look is stunning. Check out our initial hands-on with the Apple Watch Edition before our full Series 5 review later next week.
