How often does Wyze Watch refresh its weather data, is there a manual refresh function?

Specifically, how does the weather information update? For instance, is it timed to update every XX minutes? Does it refresh in response to selecting weather on the screen? Is there a way to push the refresh on demand? Obviously, the linked phone must be nearby and connected to WiFi or data, but beyond that, is there any way to know when the weather stats are updated?
