Alarm clock just vibrating without sound. Is it possible?
The first place to check about this type of questions is to take a look at the documentation:
https://www8.garmin.com/manuals/webhelp/forerunner245/EN-US/GUID-7D479786-D3AE-4F4B-AF46-35C245A56146.html
yes.
Instead of being a smart ***, why don't you actually help the OP and tell them how?
I have found it.
It was yes/no question. Second, my watch only vibrates for alarm but I did not know how I set up. Even I thought there is no sound for alarm. Last, I did not wear 245 now.
