09-08-2025I've had a 4 Classic since 2021 and there's enough to like about it that I haven't seen a watch I'd rather have. The battery life is the biggest downside. You can stretch it by running very few of its features continuously, but then what is the point of having it at all in that case? Using all the features to track your personal health journey, it is possible to get nearly full day charges, but you have to time a period of inactivity in which to fully recharge the watch in order to get through the night for sleep tracking and through the typical day. It charges relatively quickly, but this can still be hard to accomplish. Because of this, I bought a second watch here in refurbished condition. My plan is to let my day watch charge overnight while I switch to this watch for sleep tracking and use as a general backup. The Samsung Health App seems to deal with this well so far. I just turn the watch I'm going to charge off, then turn on the next watch. I never charge them while they are on. The condition of the watch was indistinguishable from new. It even came with a charger and a new band. The band is not my favorite, but it isn't uncomfortable either and will serve my purposes well. I looked at a new Watch 7 and Watch 7 Ultra, but even with longer battery life, the main problem that it eventually needs to be charged is not solved. I'm liking the solution of just having two identical watches best. As for the watch itself, I like it a lot. It isn't 100% accurate in all circumstances with all features, but it is close enough to be informative. If you need medical grade information, I'm sure you'll never find it on any watch to date. This is a heavy watch. If you don't like those, this isn't for you. My first Watch 4 Classic has survived over 3 years of use and I work blue collar type jobs. I've been surprised how tough and durable the screen is, mine still doesn't have a scratch. I think the dial bezel, which is a great feature in use, does a great job of adding protection. I got the silver color and it just looks like a classic watch with a modern flair. The grey on the band takes away from the crhrome a bit. A black band would put more focus on the watch itself.
