The overseas version and the domestic version of Jiaming are different in font, positioning system and service. First of all, there are no Chinese fonts in foreign versions, and only the Bank of China has Chinese fonts. This leads to the message reminder function of the watch. If it is an overseas version, it will become a pure display for domestic use because of the garbled code. Secondly, China Bank's products have more Beidou and QZSS positioning systems than overseas versions. This means that the domestic version supports five-star positioning, and the overseas version only supports Samsung positioning. Finally, the domestic version of the service guarantee is better. Therefore, the overseas version and the domestic version of Jiaming are different in font, positioning system and service.
