Minimal slick watch
I personally love it, small, slick, minimal, color is nice. Charging it once a day but it could last you 2 days tho if you use it just for time.

GREAT BUY!
I have no regrets in buying this! It fits comfortably and it works great, typical apple like. Personally I wanted something small, and this model was right for me, and even though the battery isn't like the other models, I can still get a full day and half with this. Highly recommend!

My Experience with the Apple Watch SE 3
I’ve been using the Apple Watch SE 3 for a while now, and I’m honestly really impressed with it. The performance is smooth and fast, apps open quickly, and notifications come in instantly, which makes it super convenient for everyday use. It’s also very comfortable to wear all day, even when sleeping or working out. I mainly use it to track my workouts, steps, and daily activity, and it does exactly what I need. The fitness tracking is accurate, the heart rate monitoring works well, and I like how it motivates me to stay active with the activity rings. The battery easily lasts me a full day, sometimes even more, which is perfect for my routine. Overall, the Apple Watch SE 3 feels like a great balance between price and features. It gives you the Apple Watch experience without paying extra for things you might not really need. I’m very happy with it and would definitely recommend it to anyone looking for a reliable and stylish smartwatch.
