12/24 hour setting on Samsung S3 Frontier not set able

All my digital watchfaces 12/24hour show only 12hour even done setting to 24hour on the phone. Why? Any solution?

Thanks

Normally you set that up in settings of a particular face, not the whole device.
You should have a little gear button in the view of that face on your phone.

Yes, I use the little button on phone. Setting to 24hour, phone watchfaces show 24hour BUT when sync to Watch it show 12hour…Maybe its the app problems???

Does it change into 24h on your phone’s preview?

Yes. When sync to s3 it show 12hour only.
