It’s not too tight but I know it’s on my wrist, I sleep with it and it’s not a pain. It’s lovely, you can pick calls, play music, pick a custom wallpaper. You cant however reply messages.Basically I love it, I have had it for 7days now I think, I’ll let you know if it ever goes bad. ### ⭐⭐⭐⭐⭐ Pleasantly surprised—this watch exceeded my expectations! *by on Reviewed in the United Kingdom 19 May 2025* I was initially hesitant to buy this because I wasn’t sure if it would work well with my iPhone. But after reading so many positive reviews saying it’s fully compatible, I decided to give it a go—and I’m honestly blown away!First off, it’s incredibly light and thin. The screen is so bright and clear too—it really looks and feels premium. The design is sleek and minimal, and both the watch and the app are really easy to use. Everything just feels intuitive.What truly sold me was the promised 10-day battery life. Coming from an Apple Watch, I didn’t think that was even possible—but the Huawei Fit 4 actually delivers on that. No more constant charging!One of my favourite features has to be the warm-up guidance before workouts. It actually walks me through stretches and prep so I don’t injure myself, which I’ve never had on a watch before. Plus, the support for up to 100 different workout modes is just insane—I’m still exploring them all!If you’re on the fence like I was, give it a try. It’s packed with smart features and really impressed me more than I expected. ### ⭐⭐⭐⭐⭐ Lovely watch *by on Reviewed in the United Kingdom 15 May 2026* Lovely watch at a good price. It was easy to set up and link to the HUAWEI app. My husband bought the pro version but when I tried it on it felt a little large/wide for my wrist. This one suits a woman’s wrist perfectly ## Frequently Bought Together - HUAWEI WATCH FIT 4 Smartwatch for Men Women, Ultra Slim, iOS & Android, up to 10 Days Battery Life, Bluetooth Call, GPS Running Smartwatch, Aluminum Case, AMOLED Display, Fitness Tracker, Black - HUAWEI FreeBuds SE 2 Wireless Earbuds, Bluetooth In-Ear Headphones, 40Hour Battery Life Earphones, with IP54 Dust and Splash Resistant, Compact Design,Compatible with Android/iOS/Window, White --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.jp/products/727723676-watch-fit-4-smart-watch-ultra-slim-bluetooth-call-aluminum](https://www.desertcart.jp/products/727723676-watch-fit-4-smart-watch-ultra-slim-bluetooth-call-aluminum) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-09-19*
