Is Apple Watch Series 10 42mm Good?
Yes, the Apple Watch Series 10 42mm is a very good choice for people who want a small, light, and smart watch. It suits smaller wrists, narrow sleeves, and users who dislike bulky wearables. It still offers the same main health tools, safety features, apps, and fitness tracking as the larger model. The main trade-off is its smaller display.
I wore the 42mm model during office work and evening walks. It felt easy to forget on my wrist, even when I wore it overnight. I could read alerts, start a workout, and check my heart rate with ease. I did need to look a little closer when typing replies or viewing long messages. In this 42 vs 46 apple watch test, the 42mm won for comfort and lightness.
