Huawei Japan announced its Japanese release for 24 November 2023 at a suggested retail price of ¥65,780 including tax; that date and price are Japan-specific, not a worldwide release date or price.

Huawei Watch 4 key features
Huawei describes the Watch 4 as having a roughly 1.5-inch LTPO AMOLED display and a curved-glass design with a surgical stainless-steel case. Huawei Japan said the bezel was about 21.6% narrower than on the WATCH 3 and that the display occupied more than about 72% of the front area. These are manufacturer claims, not independent measurements.

Huawei Japan also claims that a 15-minute charge can provide up to a day of use and that a full charge takes about 60 minutes using the specified Huawei adapter and included wireless SuperCharger. Charging time and resulting runtime depend on the stated equipment and test conditions.

eSIM, Android and iPhone compatibility
The Watch 4 supports eSIM cellular functions, including standalone calling where supported. Compatibility is not universal: check the exact watch model, country, carrier, service type and plan in Huawei’s current carrier information before buying for phone-free calling. One-number and standalone-number services are not interchangeable.
Huawei says the watch is compatible with Android and iOS phones, but feature availability and battery estimates can differ by platform and region. Check Huawei’s current compatibility information for the phone and market you plan to use. Huawei Japan’s 2023 launch notice said its Japan model required a standalone-number service and did not support one-number service at that time; do not treat that old market-specific notice as a current worldwide rule.
Huawei Watch 4 price and availability
Huawei Japan announced a suggested retail price of ¥65,780 including tax for the Japanese launch. The company said the watch would go on sale in Japan on 24 November 2023, with Amazon Japan, Huawei’s official channels and other retailers among the launch sales channels. This establishes launch plans, not current stock or a global price.
At the time of research on 4 October 2026, Huawei Japan’s purchase page displayed ¥59,860 after a checkout discount and showed the watch as out of stock. Treat that as a dated store snapshot, not a dependable current price or proof of general availability. Check local retailers for live price, stock, warranty and regional feature support.
