System Diagram

I want to make a watch, that can check my location and time. So I decide to make this watch using Wi-Fi module(WizFi250) and Cortex-M0 MCU(WIZwiki-W7500). For getting geolocation of this watch, I used ip-api.com which geolocation server and I used NTP server for getting current time. This picture is system diagram of my project.
