Can I change the dial of Apple Watch s3?

Apple 3 watch should create a graphic dial. Apple Watch can only add text patterns to the color dial.

It can't be downloaded and installed from the Internet, and no third-party App can provide more dials. After WatchOS 2, Apple Watch will add a dial, such as a time-lapse photography dial and a photo wallpaper dial. But I haven't heard that I can download the dial. As for the third-party App, this can only be taken one step at a time.

One is to consider the safety of chemical production, and the other is related to the personal safety of instrument maintenance personnel.
